Justin Maxwell not a lock to start in center field upon return

Justin Maxwell is not a lock to start in center field for the Astros when he returns from the disabled list, MLB.com reports.

"I'm going to say that he will start. I'm not going to say it will be at center field," manager Bo Porter told MLB.com Friday. "Brandon Barnes has done a great job there. He will warrant some continued playing time in center. That's why we've had Maxwell play some places beside center field [during his rehab assignment]. It gives us the luxury of having the option for both guys."

Maxwell, who has been out since April 23, is recovering from a fractured left hand.
