OBA Constitution & Playing Rules 

http://www.baseballontario.com/Admin/SideMenu/About.aspx?TopmenuID=10001

Some additional Notes....

*Call ups must be identified on line up card

*Pitch Count violations are still forfeits except when pitch counter does not notify ump, When pitch counter notifies ump after max # is reached, then pitcher is removed & manager is ejected

*Select substitutions are between innings only, except pitchers or injuries

*Jewelry is allowed except for pitcher. Pitchers cannot wear jewelry, exception for pitchers is medic alert type bracelet

*Warming up pitcher, requires a mask when

1) pitcher is on rubber (field or bullpen)

2) person catching is behind plate

3) person catching squats (anywhere)

Rep rule - One warning per team, then immediate ejection 

Select rule just says when warming up a pitcher, a mask must be worn 

I would suggest do the same as rep - one warning per team, then toss them

Rookie Rep 

*game becomes official at 5 innings or any point where the opposing team is unable to win or tie the game

Rookie at bat

*Rep no change 5 strikes as called, not out if 5th strike is foul, unless caught before it touches the ground
