When do players usually arrive at Fenway for a game?

Answer 1

Like most MLB teams, batting practice starts approximately 3 hours before gametime. There are certain situations, (noon start following a late game, rain delay) where BP is later than that.

Fenway Park's gates open two hours before game time. One person reported that the Red Sox take the field about 20 minutes before gates open, and stay out for approx 30 minutes after gates open. The visiting team then take BP for approx another hour.

Another perspective; I went to batting practice and I was there before it even began. They worked with some young guys at first at like 3 and than started in with the whole team at 4 they all stop at 5:10 for the away to start.
