CINCINNATI — Infielder Jerry Hairston Jr. went on the 15-day disabled list today with a strained hamstring, prompting the Cincinnati Reds to activate infielder Jolbert Cabrera off the disabled list.

The Reds also reinstated left-hander Bobby Livingston from the 60-day disabled list and optioned him to Double-A Chattanooga. Livingston had surgery last September to repair a torn labrum in his shoulder. Infielder Norris Hopper, who is recovering from reconstructive elbow surgery, was transferred from the 15-day to the 60-day disabled list.

Hairston pulled his right hamstring while running out a bunt on Sunday. He's batting .351 with 15 stolen bases, second on the team to Brandon Phillips' 19 steals.

"I tried running on it, and it didn't feel right," Hairston said today. "We all got together and decided that it'd be better if I shut it down instead of trying to run something out and maybe blowing it out and missing a month."

Cabrera dislocated the index finger on his left hand while sliding into second base against the Yankees on June 21.
