ST. LOUIS -- Albert Pujols will not be participating in this year's Home Run Derby, the slugger told Fox Sports Midwest on Monday.

"I don't have any problem doing it, but I want to concentrate on the second half," Pujols told B.J. Rains of FSM. "I enjoyed every moment that I did it. I don't regret it, and that doesn't mean I would never do it again. I wouldn't mind doing it again. I just feel that, right now, this is not the time."

Although Pujols has not been officially invited, the eight-time All-Star was leading the fan-participation ballot, and competed in last year's contest in St. Louis.

Pujols is currently tied for first on the Cardinals with 16 home runs, leads the club with 51 RBIs and is second in slugging with a .542 percentage.
