11U (Mosquito) division is for youth who are 10 and 11 years of age, and is the first division in which players begin to pitch and catch. A real baseball is used for the first time. Players are not permitted to sit out for extended periods of time. All players are kept in the batting lineup and rotated by position.
Teams are usually 12-15 players. At this level, games will be defaulted if the required number of players are not at the field at game time. Eight players are needed to start a game and seven to finish.
Games are played Mondays and Wednesday nights at St. Peter's Field at 6:00pm and 8:00pm.
Mount Pearl Minor Baseball recommends that when one team is short players at the beginning of a game, that they borrow players from the opposition, or both teams may be combined to play a game. A practice session may also take place instead of a game
In the event of rain, an announcement concerning the scheduled games for that evening will be posted to the website at 4:00pm
