Do you know if the game will get cancelled for tomorrow night game due to the Rain???

Richmond Lori said it perfectly

Actually the game will stay scheduled up to first pitch - the rain may causes a delay - and the game will continue. If the game is called it will be sudden, they want to play the game and rain isn't going to stop them. UNLESS the flood waters rise too high and puddles on the field are too dangerous.

Check the Giants website tomorrow and you'll find out.

Game time decision

Its a game time decision
