Collateral Damage Daily for September 25

David Freese sprained his right ankle during batting practice yesterday and had to leave the game early. It does not appear to be a serious injury; he is day-to-day. … Mike Olt took batting practice yesterday but appears to be several days away from returning. … Carlos Gonzalez had an MRI yesterday on his strained left hamstring, and the Rockies may keep him out for the rest of the season as a precaution. … Fernando Abad left the game yesterday with a strained right oblique and is day-to-day. … Jason Giambi is dealing with his viral illness again and was unavailable yesterday. … Michael Brantley was out of the lineup yesterday because of groin soreness and is day-to-day. … Dexter Fowler is dealing with right wrist tendinitis and is day-to-day. He did come in as a defensive replacement yesterday. … Randy Wolf will get an MRI on his left elbow tomorrow after feeling soreness following his Saturday start.

Additions

• J.D. Martinez will undergo surgery on his left wrist tomorrow in order to repair a small fracture in his hamate bone that has been bothering him throughout the season. The procedure will remove the hook of the hamate bone. The injury was not a constant pain—it was relieved with treatment—but the pain recently increased. Rehab is fairly straightforward, and the Astros hope he can make it back in time for winter ball.

Subtractions

• Matt Capps was activated from the 15-day DL after missing 69 days with right shoulder inflammation.
• David Aardsma is expected to be activated from the disabled list today after spending the last two years recovering from hip and elbow surgeries. He has missed over 300 days in the last two years rehabbing from surgeries and looks to be part of the bullpen down the stretch.
