SAN DIEGO (AP) - The Houston Astros have activated left-hander Mike Hampton from the 15-day disabled list.
Hampton, who has been on the disabled list since June 14 with a left groin strain, was the starter Tuesday night against the San Diego Padres.
Hampton is 4-5 with a 4.70 ERA in 12 starts this season. He has started against the Padres 25 times, but has not faced them since 2005.
The Astros optioned left-hander Wesley Wright to Triple-A Round Rock following Monday night's game to make room for Hampton.
