Astros manager Bo Porter suggested Friday that Justin Maxwell (hand) may not be the starting center fielder when he returns from the disabled list. Maxwell is still locked into a starting job, but could be used in one of the corner outfield spots. "I'm going to say that he will start. I'm not going to say it will be at center field," Porter said. "Brandon Barnes has done a great job there. He will warrant some continued playing time. That's why we've had Maxwell play some places beside center field [during his rehab assignment]."
