The Houston Astros have placed shortstop Jed Lowrie and catcher Jason Castro on the disabled list, the team announced Sunday.
Lowrie suffered a sprained ankle and nerve damage in his lower leg after a collision with Giants OF Gregor Blanco at second base Saturday night. Lowrie's leg bent as he turned away when Blanco slid into his foot.
Infielder Marwin Gonzalez, who returned from a rehab assignment this weekend, will get most of the playing time at shortstop.
Castro's move is retroactive to July 8 because of swelling in his right knee. It's the same knee that was surgically repaired last season.
"I've been told that this is somewhat normal for coming off the surgery I had," Castro said. "Up to this point, I haven't had swelling or anything like this before, and with the amount of playing time I was having before the All-Star break, it was a fairly common thing to happen."
Lowrie has a .253 batting average with 14 home runs and 36 RBIs. Castro is hitting .254 with two home runs and 20 RBIs in 54 games.
Castro will be replaced by catcher Carlos Corporan, who had his contract purchased from Class AAA Oklahoma City.
