when does practice for the dodger usually end on game days?

A couple of hours before the game starts.

90 minutes before game time

Gates open at 9,1130 practice ends

I believe gate opens at 10? There was only one entry into the stadium itself from what I understand so the line was long. But I think the practices are at the fields adjacent to the stadium field so you can walk in and hang out watching and looking for autograph opportunity!
