-- Ken Griffey Jr. went on the 15-disabled list Sunday with a torn right hamstring and will miss the All-Star Game.

The Cincinnati outfielder was injured Saturday night while trying to run down Brady Clark's fourth-inning drive to right-center in the fourth inning of a 5-0 loss to Milwaukee. An MRI exam Sunday revealed a partial tear of the muscle.

Carlos Beltran of the Houston Astros will replace Griffey on the roster. Griffey plans to go to Houston to participate in ceremonies, but will not take part in the Home Run Derby or the game, Reds spokesman Rob Butcher said.

"He'll be reevaluated on a regular basis," Reds trainer Mark Mann said. "He told me he heard it pop. At the end of the 15-day period, we'll have a better idea of a time frame. It's a muscular tear, so this should heal on its own."

Griffey was voted an all-star starter for the 12th time last weekend. He missed more than a month with a torn hamstring that bothered him throughout the 2001 season. He spent two long stints on the 15-day disabled list with a torn patella tendon and a torn right hamstring in 2002, then went to the DL twice again last year for a dislocated right shoulder and torn ankle tendon.

Mann talked with Griffey on Sunday.

"He's doing okay," Mann said. "We've been down this road before."
