MNBA T-Ball Rules 1 Revised: May, 2015.
The Game of T-Ball: T-Ball is a game of baseball between two teams of players under the direction of a manager and coaches played in agreement with the playing rules under the authority of an Umpire or Umpires on a recommended T-Ball field. It is designed to get young children interested in the game of baseball by stressing and maintaining active participation of all the players: with mandatory alternation of players at a game with the offensive team utilizing their players as batters to score as many runs as possible and the defensive team using their players to make as many outs as possible in accordance with the rules.
The objective of MNBA T-Ball is to develop fundamental skills (i.e., hitting, running, fielding, throwing, and catching) and general knowledge of the game of baseball.
General Rules: If a rule is not found in this handbook, then Baseball Canada Official Rules of Baseball apply.

Senior T-Ball Teams must field a minimum of 6 players and maintain at least 6 players for the whole game. In the event that one team cannot field 6 players by the end of the grace period or either team drops below 6 players during the game, the Umpire will award the game to the non-offending team by default. The score will be recorded as 7-0.
There are no player minimums for Junior T-Ball.
If neither Senior T-Ball team can field 6 players it will be considered a no game and will be rescheduled. At the discretion of the two coaches, an exhibition game can be played.
Each game will consist of: 3 innings – Junior T-Ball | 4 innings – Senior T-Ball
Mississauga North Baseball Association | House League T-Ball Rules
MNBA T-Ball Rules 2 Revised: May, 2015.
Until the completion of the school year (3rd or 4th week in June), no new inning may start after 7:45 p.m. for Junior T-Ball games and 8:00 p.m. for Senior T-Ball games.
A regulation game will be considered complete if a minimum of 3 innings are completed or the go-ahead run is scored in the bottom of the third inning and the game is called by the Umpire.
If one complete inning or more has been played, and the game cannot be continued, it will be considered a suspended game. Suspended games will be continued at a later date. The same batting order, number of outs, positions of base runners, etc. will be followed. In the event new batters appear for the rescheduled game, they will be placed at the bottom of the batting order (before Last Batter). If previous batters are not at the rescheduled game, the batting order will be compressed as if they had never played and again new batters will be placed at the bottom of the order (before Last Batter).
In the event that one inning had not been completed, the rescheduled game will be considered a new game and will start from the beginning. The old line up need not be followed.
If a Senior T-Ball game is called during the fourth inning, it will be considered an official game. If the home team has tied the score or has scored the go ahead run in the called inning, the score will be recorded as it is then. If not, the score will revert back to the score at the end of the last inning.
If a player wishes to use a non-league supplied bat, the Umpire must approve it. If a player uses a non-league supplied bat (with the approval of the Umpire) the entire team may use that bat.
One (1) Umpire may umpire a game. In the event that no Umpires appear, the home team coach should notify the Director. One substitute Umpire may be chosen from each of the team’s parents, if no Umpires are present at the game. Upon late arrival, an Umpire is to take his/her place at the nearest half inning. A game is not in default if no carded Umpires attend. Exception: Does not apply to Junior T-Ball as no Umpires are supplied for these games.
The home team is responsible for diamond layout prior to each game. The visiting team should assist with the diamond layout. Home team must occupy the third base side of the field. Exception: During Senior T-Ball playoffs a coin toss determines home team.
Senior T-Ball, coaches should notify the Director in the event that no Umpire shows up to their game.
Coaches and Umpires shall meet at home plate at 6:10 p.m. regardless of the number of players to discuss rule interpretation and ground rules.
Verbal harassment of an Umpire before, during or after a game, will not be permitted or tolerated. Violation of this rule will result in immediate ejection and suspension of the next game (balance of current game and the next game) suspension for the coach. Based on the severity of the violation or for repeat offenders, the House League Board may increase the length of the suspension.
Physical abuse will not be tolerated and is an automatic suspension until further notice.
Mississauga North Baseball Association | House League T-Ball Rules
MNBA T-Ball Rules 3 Revised: May, 2015.
Junior T-Ball – all players field in any inning.
Senior T-Ball – a maximum of 11 players field in any inning.
The entire roster present will bat in each inning. The number of players on the team having the most players present will determine the number of batters. If team “A” has 13 players and team “B” has 12 players, 13 batters will bat. Team “B” will make up the shortage by using a make-up batter (See make-up batter rule). Batting lineups must be exchanged between teams before the game begins.
All players (including call-ups) must play at least half of each game and no player shall sit out twice before all other players have sat out at least once. Unlimited substitution rules will apply. If a violation of this rule is discovered, the Umpire should be notified at the time of the occurrence so the situation can be rectified immediately. A warning will be issued to the coach violating the sit-out rule. A second offense in the same game by the same team will result in ejection of the head coach. If the violation is not identified at the time it occurs, the infraction is nullified.
Sit-Out Exceptions:
a) a player who is injured
b) a player who is being sit out for disciplinary reasons
c) a player who has requested it
A coach must justify to the House League Director any player discipline in relation to Rule C3 (b). In any of the above cases coaches must notify the Umpire and the opposing coach of any of the above exceptions are invoked.
Team players arriving while their team is in the field are allowed to enter the field at the next stoppage of play.
Team players arriving while their team is at bat can be inserted at the bottom of the line up, directly before the Last Batter, if their team requires make-up batters or it is the first half of the inning. The other team should be notified immediately so that they can adjust their own batting order (i.e., they now need a make-up batter or to delete a make-up batter on their roster).
Both teams must have an equal number of batters. Make-up batters placed directly before the Last Batter will be used to equalize the number of at-bats.
Mississauga North Baseball Association | House League T-Ball Rules
MNBA T-Ball Rules 4 Revised: May, 2015.
The order of make-up batters starts at the top of the batting order and proceeds through the batting order from one inning to the next, excluding the Last Batter. The Last Batter cannot be a make-up batter. For example: 2 make-up batters are required. In the 1st inning use your 1st and 2nd batters. In the 2nd inning use your 3rd and 4th batters, etc. If your make-up batter is on base, replace him/her with a pinch runner. This should be the Last Batter who has returned to the dugout and is not scheduled to bat again in that inning.
Each defensive team shall have the following players:
a catcher, playing behind home plate far enough back to avoid interfering with the batter’s swing;
a pitcher, who must assume a position on the imaginary line running from first to third and directly in front of home plate;
a first baseman;
a second baseman;
a short stop;
a third baseman; and
two to five outfielders.
Additional players (i.e., 2 short stops and/or 2 second basemen) may be placed in the infield during the regular season only. This is to encourage more defensive player contact with the ball and not have four or more kids play the outfield where the ball is infrequently hit. Should additional players be placed in the infield, they may not be repositioned for Last Batter as noted in C.8.
Once a player assumes a defensive position at the start of an inning, he/she may not be assigned another position in the field during that inning except to replace a player removed due to injury or sickness.
All infielders must be placed in fair territory in the infield and behind the Pitcher’s Line.
All infielders shall not cross the pitcher’s line until the ball is hit.
Players must be given the opportunity to experience all infield and outfield positions.
The pitcher must throw the ball to a base or home plate. The pitcher cannot make a force out or tag out a runner that is running to a base (1st, 2nd, or 3rd base) or home plate. The purpose of this rule is to encourage the players to learn the fundamentals of baseball (i.e., throwing and catching the ball). All other defensive players on the field can make force outs or tag outs at any of the bases and home plate.
All players must throw the ball overhand, except in situations when the receiving player is too close to the throwing players. If the ball is thrown underhand or rolled when in the Umpire’s judgement, it should have been thrown overhand, the runner shall be called safe.
Mississauga North Baseball Association | House League T-Ball Rules
MNBA T-Ball Rules 5 Revised: May, 2015.
Outfielders must play in fair territory beyond the infield area. Outfielders must position themselves at least 10 feet behind the baselines until the ball is hit. Once the ball is hit, outfielders can enter the infield area to participate in the play.
The pitcher must wear an approved helmet. A face cage is recommended for player's batting helmets. These can be purchased and affixed to most standard CSA approved batting helmets.
The catcher must wear all equipment as supplied by the League and assume the normal catcher’s position.
Three defensive coaches are allowed in the field for Junior T-Ball throughout the entire season and up to and including the 6th regular season game for Senior T-Ball. The three coaches may take their positions on the playing field while their team is on defense in order to verbally encourage, direct players towards a play or keep players alert to the game. The coaches may not interfere with the ball, and may not physically assist a defensive player in making a play while the ball is in play.
Penalty – If, in the Umpire’s judgement a coach intentionally interferes with the ball or provides any physical assistance, the ball is dead and the Umpire awards bases if required.
Exception: Defensive coaches are allowed on the field up to and including the 6th game of regular season play for Senior T-Ball.
All players shall bat in each inning.
A player must be listed to bat in the same batting position for each inning. When it is recognized that a batter misses his turn at bat, the batter should bat at the first opportunity without penalty. After the play begins, changes or additions to this line-up must be made before the Umpire calls “play” for the first batter at the beginning of an inning, except in the case of injury or sickness. All line-up changes must be reported to the plate Umpire, the scorekeeper and the opposing manager.
Batting Orders: must be followed for each inning.
All rained out, cancelled, or suspended games must be rescheduled and played within two weeks of the original date if possible or be forfeited by both teams (i.e., no game). Rescheduling is the responsibility of the home team coach and arrangements shall be reported to the House League Director to allow the appointment of Umpires. This must be done at least 3 days prior to the game.
Exception: Does not apply to Junior T-Ball
Rescheduled games normally take precedence over the use of diamonds for practices. The House League Director will arrange to have another team’s practice cancelled, if necessary.
Any game can be ended during any inning at the Umpire’s discretion (i.e., thunder, etc.) If lighting is seen, the game must be called immediately, no exceptions. Play may
Mississauga North Baseball Association | House League T-Ball Rules
MNBA T-Ball Rules 6 Revised: May, 2015.
resume, at the Umpire’s discretion, a minimum of 15 minutes after the last lightning is seen.
It is recommended that scorekeepers for both teams compare and agree to the number of runs scored after every half inning played. Any discrepancies should be addressed at that time and clarified before the next inning starts.
All game scores to be reported on the House League website after each game. House League coaches will be given a password for access to enter scores. The winning team is responsible to report the score. Game score sheets should be retained to resolve any score discrepancies.
Exception: Scores are not reported for Junior T-Ball.
Note: Definitions are listed in alphabetical order.
Appeal – must be made before “PLAY” is called for the next batter. In the case of the Last Batter, it must be made before the last defensive player has left the playing field.
Appeals may be made by the defensive team for:
(a) base runners missing any base, or
(b) Base runners failing to tag-up on a caught fly ball.
Base Distance:
Junior T-Ball 45 feet
Senior T-Ball 50 feet
If park dimensions are such that these distances would put the bases on the grass, then they will be moved to one foot inside the grass.
Batter Box – is an area on each side of home plate in which the batter shall have both feet during his/her time at bat. It is 3 feet by 6 feet and 4 inches from, and centered on, the sides of home plate.
Catcher’s Area – an area around home plate into which no player, other than the pitcher and catcher are allowed after the Last Batter has hit the ball.
For Senior T-Ball, the Catcher’s Area can be determined by measuring a point fifteen (15) feet up the first base line, a point fifteen (15) feet up the third base line, and a point 15 feet in front of home plate directly in line with second base.
For Junior T-Ball, the Catcher’s Area can be determined by measuring a point ten (10) feet up the first base line, a point ten (10) feet up the third base line, and a point 10 feet in front of home plate directly in line with second base.
An arc is drawn to join these three points (same as Dead Hit Line). The Catcher’s Area also includes the foul territory immediately behind the Dead Hit Line. The lines that
Mississauga North Baseball Association | House League T-Ball Rules
MNBA T-Ball Rules 7 Revised: May, 2015.
extend beyond the foul lines that define the Catcher’s Area are perpendicular to the foul lines.
On Last Batter, the catcher must stay in the Catcher’s Area and cannot cross the Dead Hit Line. On the Last Batter, the ball must be thrown by an offensive player over the Dead Hit Line to the catcher. Should the catcher cross the Dead Hit Line on Last Batter to obtain the ball, all runs score.
Dead Hit Ball – is a legally batted ball,
(a) which in the Umpire’s opinion did not cross the dead hit line or could not have crossed the Dead Hit Line firmly, even if fielded in front of the Dead Hit Line.
(b) If the ball is caught in flight, the batter is out and the ball is live.
Dead Hit Line – Two points are established by measuring fifteen (15) feet (for Senior T-Ball) and ten (10) feet (for Junior T-Ball) from Home Plate towards first base and third base. A third point is established 15 feet (for Senior T-Ball) and 10 feet (for Junior T-Ball) from home plate, directly in line with second base. An arc is drawn connecting these three points. Refer to the Catcher’s Area. D7. Encroachment Area – Refer to the Catcher’s Area (See F.4).
Fair Hit Ball – is a legally batted ball that, in the Umpire’s opinion, did or could have firmly crossed the dead hit line in fair territory, even if it is fielded before crossing the dead hit line. On a fair hit ball that does not leave the infield, runners may not advance more than one base. On a fair hit ball that leaves the infield, runners may advance to the closest empty base once the ball enters the infield. The infield/outfield areas are defined by a theoretical line that connects first base and second base, and second base and third base.
Fielder’s Choice – when any defensive player has control of the ball, in the infield area, and in the judgement of the Umpire there is no attempt to make a play on any of the base runners or batter, TIME will be called, and the base runners, in the judgement of the Umpire, will be held on the base they last occupied or will advance to the base they were approaching when time was called. A player holding up the ball will not automatically attain a call of time.
Illegal Swing – when the batter does not take a full swing or chop swings downward on the ball. This is considered bunting. The ball will be considered a foul ball. The ball is dead and no runners may advance.
Infield Area – is an area encompassing the bases and a few feet beyond, normally to the grassed area in most diamonds. It also includes the adjacent foul territories.
Lead-off – when a runner is off the base before the batter hits the ball.
Pitcher’s Line – an imaginary line extending from 1st base to 3rd base on which a pitcher must stand before the batter makes contact with the ball. The intention of this line is to ensure the pitcher and infielders play in their proper positions. After the ball is hit, the pitcher and infielders are allowed to move off the line to make a play.
Playing Field Boundaries – the playing field includes all of fair territory to the outfield fence, or in the absence of an outfield fence, an imaginary line representing one; and foul territory to the backstop, adjacent fence extensions and an imaginary line extending
Mississauga North Baseball Association | House League T-Ball Rules
MNBA T-Ball Rules 8 Revised: May, 2015.
from the end of the backstop and fence to the outfield fence. The Umpires and coaches will review playing field boundaries prior to the start of each game.
Playing Line – Refer to Pitcher’s Line
Strike – Definition
(a) the ball is swung at and both the ball and tee are completely missed.
(b) the ball is dead hit or fouled when the batter has less than two strikes.
Thrown Bat – when the batter releases or throws the bat in such a manner, in the opinion of the Umpire, it could cause either the catcher or the Umpire to be hit with said bat.
Penalty: The first occurrence will result in a warning. On the second occurrence the batter is out. However, play continues and the ball is live until time is called, all outs and legal advancements will stand. After time is called, the Umpire will call “Batter Out – Thrown Bat”.
Example: Runners on 1st and 2nd and the batter hits to short-stop and then throws the bat and hits the catcher with it. Short stop throws to 3rd and gets the runner from 2nd out, runner from 1st is safe on 2nd and the batter is safe on 1st. The Umpire calls the batter out, the lead runner is out at 3rd and the base runner is safe at 2nd.
Advancing Bases – runners may only advance to another base as a result of the ball being hit off the tee or catcher’s interference or obstruction. If a play is made to 1st base or 3rd base, runners cannot advance any further. For example, if a runner is on 2nd base, and the batter hits the ball to an infielder that makes a play at 1st base, the runner from 2nd advances to 3rd base. Runners may advance bases if the ball is in the outfield or a play is being made on them. Once the ball enters the infield, runners should hold at the closest base. The advancement of runners is at the discretion of the Umpire. The exception to this is the Last Batter.
Minimum Roster Rule - Teams playing with a minimum roster where outfield positions are vacant.
(a) Any ball hit to an unoccupied (undefended) outfield area through the infield on the ground will be deemed a single and the batter and any base runners will be entitled to one base.
(b) Any ball hit to an unoccupied (undefended) outfield area in the air will be deemed a double and the batter and any base runners will be entitled to two bases.
(c) Any ball hit in the air to an unoccupied (undefended) outfield area beyond the limits of the predetermined playing field boundaries (see F.13) will be deemed to be a home run.
Exception to above: None of G.2 applies to the Last Batter. The Last Batter must be retired in accordance with G.14 (a), (b), (c) or (d).
Bunting and stealing are not permitted (see F.9).
Mississauga North Baseball Association | House League T-Ball Rules
MNBA T-Ball Rules 9 Revised: May, 2015.
The Infield Fly rule does NOT apply.
Runners may tag-up and advance on caught fly balls.

(b) he/she has three strikes on him/her; or
(c) he/she throws the bat a second time in a game. (see F.16).
A batter becomes a base runner when:

(b) he/she is tagged off a base;
(c) he/she runs more than 3 feet off the base path to avoid being tagged unless this was done to avoid interference with a fielder fielding a batted ball;
(d) after touching first base, he/she leaves the baseline, obviously abandoning his/her efforts to touch the next base, e.g., returns to the dugout (see Official Rules of Baseball Section 7.08);
(e) he/she is hit by a fair batted ball, either on or off the base, before it touches or passes an infielder other than the pitcher;
(f) he/she fails to return to his/her base following a fair fly ball caught by a fielder, before the ball is returned to that base;
(g) he/she is tagged, on or off a base, BEFORE returning to his/her original base following a fair caught ball;
(h) he/she interferes with a fielder attempting to make a play on a hit or thrown ball;
(i) when, while approaching home plate, a member of his/her team interferes with a defensive player attempting to make a play;
(j) he/she is physically assisted by a Coach while the ball is live;
(k) he/she occupies the same base as the runner ahead of him/her and is tagged by a defensive player. It two runners occupy the same base, time will not be called until one runner has been put out or one runner has reached another base.
Mississauga North Baseball Association | House League T-Ball Rules
MNBA T-Ball Rules 10 Revised: May, 2015.
Overthrows – if a ball is thrown by a defensive player or batted ball touched by a defensive player leaves the playing field, the base runner(s) will be permitted to advance to the base they are approaching plus one base, AT THE TIME OF THE THROW. If a ball is thrown to 1st or 3rd base in an attempt to force or tag a runner out and the ball goes out of play, the runners may not advance.
On Last Batter, all legal runs score. Runners must continue around and touch each base. If, on Last Batter, a fly ball is hit and caught, only those runners legally tagging up at their original base are allowed to score (i.e., the runners must be touching the base at the time the ball is touched and then advance to the next base). On Last Batter, if the ball goes beyond the playing field boundaries then all runs score. The limits of the playing field should be established during the pre-game meeting at home plate with the Umpire(s).
Lead-offs – when any base runner has taken a lead-off, time will be called immediately and the player will be sent back without penalty.
No member of the defensive team, while not in the act of receiving the ball, may impede a runner on the base path. If, in the Umpire’s judgement, this occurs, and the runner is out, the Umpire will award the runner the base he/she was going to or the base the Umpire feels the runner would have reached had he/she not been interfered with. Even if the runner is not put out the Umpire can award extra bases to the runner.
A team’s turn at bat ends when:
(a) the Last Batter strikes out;
(b) the Last Batter hits the ball illegally;
(c) the Last Batter’s fair hit ball is returned to the Catcher and he/she touches home plate; or
(d) the Last Batter’s fair, foul or dead-hit ball is caught in the air and there are no runners on base.
Base runner with Last Batter Status
(a) offensive players on base when Last Batter is at bat are regarded in the same manner as Last Batter. They are all forced to home plate when Last Batter hits the ball fairly. No defensive play can be made on them other than at home plate. Exception: a throw to a base for an appeal (example: runner failed to touch a base. That runner will be declared out and the run will not be counted).
(b) in the event that the Last Batter’s fair, foul or dead hit fly ball is caught, the batter is out, and the base runners are allowed to score provided they have tagged up after the ball was caught. The runner(s) must score before the ball is returned to the catcher and he/she touches home plate.
Defensive Fielding on Last Batter
(a) If the Last Batter’s fair hit ball is hit across the dead hit line, it must be thrown over the dead hit line at least once on its return to the catcher. Play will continue. All legal runs will score. Please note that the catcher cannot cross the dead hit line to retrieve the ball.
Mississauga North Baseball Association | House League T-Ball Rules
MNBA T-Ball Rules 11 Revised: May, 2015.
(b) If the ball is fielded in front of the dead hit line it may go directly to the catcher. On Last Batter situation, the catcher must make the out at home by touching home plate with the ball or any part of his/her body while holding the ball.
(c) If the Last Batter’s ball is caught in the air, only those runners who tagged up on their original base are allowed to score and only if they have not touched a base in front of their original base or have not left their base path. They must touch home plate before the catcher (with the ball) does.
The offensive team shall announce “Last Batter” to the plate Umpire. The plate Umpire will announce “Last Batter, READY IN THE FIELD” to the defensive team. Failure to announce this does not nullify the play.
In the event that the Last Batter of the offensive team, or any runner on base during the Last Batter status is obstructed in any manner, by a member of the defensive team, while running the bases, it shall be at the discretion of the Umpire as to how far he/she should have advanced had there been no obstruction.
In the event that any offensive player or Coach, in the opinion of the Umpire, interferes with any defensive player making a play on the ball on Last Batter, TIME will be called and no further runners will be allowed to score.
See MNBA House League Rules
Home team will be determined by the Umpire’s coin toss.
Both teams are responsible for the diamond layout.
