No Ties in EOBA Regular Season Games!

When the score is tied play cannot end unless there is a park curfew or a situation where the lights go out; the game continues regardless of inning or time until a winner is determined. If the tie is in game 1 of a scheduled doubleheader, game 1 should continue until a winner is determined before game 2 commences.


The Intentional Walk - 2019

The defensive team may intentionally walk a batter before or during at at bat by the manager / coach notifying the umpire. The umpire will call time and award the batter first base and advance any other runners forced to advance by the batter being walked. Only pitches thrown will be added to the pitch count.


When thunder roars, GO INDOORS!

Baseball Ontario follows Environment Canada guidelines with respect to lightning safety:
When thunder roars, GO INDOORS!

If you can hear thunder, you can get hit by lightning. Take shelter immediately. If you cannot find a sturdy, fully enclosed building with wiring and plumbing, get into a metal-roofed vehicle. Stay inside for 30 minutes after the last rumble of thunder.

Direct strikes are responsible for only 5% of lightning-related deaths and injuries. Two other types of hazardous phenomena are caused by lightning. Ground current and side flash account for 60 to 80% of lightning-related injuries and deaths. A ground current is set up when lightning hits the ground, spreads out and sends a current through a victim. Side splash occurs when lightning hits a tall object, travels partly down the object and then jumps to a nearby victim.
