KANSAS CITY -- Center fielder Brandon Barnes was not in the lineup on Sunday because of tightness in his left hamstring.
Barnes tweaked the hamstring in the first inning of Saturday's 7-2 loss to the Royals while fielding David Lough's leadoff single. He exited the game prior to the bottom of the sixth.
"It's a little bit tight and I told Nate [trainer Lucero], there's no sense in pushing the envelope," Astros manager Bo Porter said. "Center field is a demanding position. You can get into some long runs and quick motion. I'd rather give it a day or so rather than having him look at 15 days on the disabled list and rehabbing."
