Upton missed the Padres' three games against the Giants over the weekend, and he is set to begin his second half Monday night. He was in the starting lineup, leading off and playing center field.
"We talked about it yesterday if it was best to get [Upton] a day off and take BP," Padres manager Andy Green said. "But we felt pretty good about getting out here and getting to work today. Everybody, over the All-Star break, takes three, four days off. His was twice as long because of what he's been through, but he wants to get back on the field and play baseball."
Upton batted .262/.311/.454 during the first half with several highlight-reel plays, including three walk-off home runs, three robbed home runs and a straight steal of home.
