what's the record for most home runs in a game?

Question

I've heard it was 4, but i'm not sure.

If someone knew who did it, when, and how many that'd be great.

Answer 1

The most in an 9 inning game is indeed four, and quite a number of players have done it.

Carlos Delgado played for Toronto and did it on 09-25-2003
