Kemp was placed on the disabled list last week with a recurring hamstring strain and is expected to be out a month. He said the Home Run Derby would be "just like batting practice, get ready for the second half."
Kemp spent part of Tuesday at the MLB Fan Cave in New York with American League Home Run Derby captain Robinson Cano, a former teammate from winter ball.
"It's nice to see how far we both have come," said Kemp. "He's on top of his game, and I've done pretty good and we're both captains of the Home Run Derby. That's kind of special."
So is, Kemp said, being the league leader in All-Star votes.
"I didn't know until the press conference and they showed the clip of each player and the votes. Dang, that's a lot of votes," Kemp said. "I'm really shocked and happy the fans are supporting me. I'm surprised and happy at the same time."

Teammate Andre Ethier is fourth in outfield voting, the only other Dodger to be listed in the top five at any position.
Kemp, who led the NL with 39 home runs last season, returns for his second Derby appearance. The 2011 NL All-Star is just the fifth Dodger to participate in the Derby along with Steve Garvey (1985), Mike Piazza (1993-94), Raul Mondesi (1995) and Hee-Seop Choi (2005).
Among NL players this season, the outfielder is currently tied for sixth with 12 home runs, raising his career total to 140 in seven Major League seasons.
Kemp and Cano will select and invite the other three participants on their teams, as well as a charity for which to play.
Kemp has nearly two million votes, more than 600,000 votes ahead of Cincinnati first baseman Joey Votto, the next highest vote-getter.
