Barnes, Martinez day to day with minor injuries

HOUSTON -- Astros manager Bo Porter said he doesn't anticipate having to make a roster move to bring a player up in time for Wednesday afternoon's series finale against the A's despite losing a pair of outfielders Tuesday night to injuries.

Starting center fielder Brandon Barnes left the game after six innings with a mild left calf strain he suffered running the bases in the fifth inning, and starting left fielder J.D. Martinez had a left lower back contusion following a collision with center fielder Justin Maxwell in the ninth inning.

Both players are considered day to day and will be reevaluated before Wednesday's finale.

"I think we should be OK," Porter said. "Both of those guys, it's a bruise and it's one of those things where you don't want to try to push the envelope, especially at the point we were at with J.D. It was the middle of the inning and you're out there holding up the game. It was more a question, 'Can you go right now?' Not, 'Can you go in the next 15 minutes?' We made a decision to get him out of the game, as well."

Barnes, who made yet another terrific diving catch in center field earlier in the game, said his calf was stiff and wasn't so sure it would have enough time to heal in order for him to play Wednesday.
