Astros SS Lowrie placed on 15-day DL

The Houston Astros have placed shortstop Jed Lowrie on the 15-day disabled list with a sprained right thumb.

The Astros had hoped that Lowrie would be ready for opening day on Friday against Colorado, but he wasn't quite healthy enough to play.

He was injured March 28 and his time on the disabled list is backdated to March 29. He is eligible to come off the disabled list on April 13 and he says he is confident that he'll be able to play then.

Lowrie, who was traded to Houston from the Boston Red Sox in the offseason, hit .333 with two home runs and seven RBIs in 14 games this spring.

The Astros purchased the contract of infielder Brian Bixler to take Lowrie's spot on the roster.
