Astros SS Jeremy Pena, 1B Christian Walker exit with injuries

Astros shortstop Jeremy Pena and first baseman Christian Walker departed with injuries on Saturday against the Baltimore Orioles.

Pena displayed discomfort during his second plate appearance against Orioles left-hander Trevor Rogers before striking out in the bottom of the third inning. Pena, visited by Astros manager Joe Espada and a member of the training staff during the at-bat, was replaced defensively by Nick Allen for the top of the fourth.

The Astros announced that Pena sustained a hamstring cramp. He missed 32 games earlier this season with a Grade 1 hamstring strain.

Walker was visited by Espada and a trainer during his second at-bat in the bottom of the fourth. He departed immediately and was replaced by pinch-hitter LaMonte Wade Jr. According to the club, Walker left with right hip tightness.

This season, Pena has posted six home runs, 22 RBIs and .357 on-base percentage in 52 games. Walker has recorded 20 home runs and 58 RBIs in 97 games.
