"All-Star right fielder Justin Upton says he'd like to participate in the Home Run Derby if given the chance, and manager Kirk Gibson expressed no reservations about Upton entering the contest.

The Derby will have a new twist this season. Each league has a captain - Milwaukee's Prince Fielder (National League) and Boston's David Ortiz (American League) - tasked with making three selections.

Upton was asked if he plans to talk with Fielder this week in Milwaukee, where the Diamondbacks open a three-game series this afternoon.

"I definitely would do the Derby in front of the home fans, but I'm sure he's got some big boppers in line that he's going to be taking," Upton said. "We'll see."

Managers occasionally express hesitation about their players participating in the Derby, the thinking being that their swings can get out of whack for the second half when they try to swing for the fences. Gibson didn't seem concerned.

"It's probably something that's pretty exciting to do," Gibson said. "It's a great stage to do it. If you had an opportunity to do it, why wouldn't you do it? It's an endurance test for sure.""
