A's left-hander Brett Anderson, working his way back from a stress fracture in his right foot, threw 40 pitches in Houston Wednesday in his second bullpen session of the week.
"He feels as good about this one as he did about the last one, maybe even better," manager Bob Melvin said, according to MLB.com. "I wasn't out there for this one, but he came in with a smile on his face and said he was nastier this time than he was last time."
Anderson will throw another bullpen session this week and the goal is to get him ready for a rehab assignment before a potential return to the A's rotation in mid-August.
Before being place on the disabled list on May 1, Anderson was 1-4 with a 6.21 ERA in 29.0 innings.
