Matt Lindstrom delays bullpen session

NEW YORK -- Houston Astros closer Matt Lindstrom still has a stiff back and his scheduled bullpen session has been delayed.

Astros manager Brad Mills says Lindstrom was scheduled to throw Saturday before heading out on a rehab assignment. He will be evaluated daily to see if he's ready to throw.

Mills said infielder Jeff Keppinger (left big toe) is expected to play a rehab game at Double-A Corpus Christi on Sunday.

Houston infielder Geoff Blum returned after missing three days with neck discomfort. He batted for pitcher Brett Myers in the top of the eighth and struck out to end the inning.
