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.
The NFL teams arrive at the stadium before the game. They leave when the game is finished.
Players usually arrive 3 or 4 hours in advance of the game. This gives them time to suit up, do a light workout, meet with coaches and managers, etc. One exception is when a west coast team travels east directly after a night game on the west coast. They may get to the park only shortly before the game.
