OAKLAND -- Astros manager Bo Porter admitted Thursday he was concerned about the sore right hamstring of starting shortstop Marwin Gonzalez, who was lifted in the seventh inning of Wednesday night's 9-7 loss to the A's to rest the leg.
Gonzalez was in the lineup Thursday out of necessity, considering the Astros' mounting injury problems. Enrique Hernandez can play shortstop, but he's been put in center field, with Dexter Fowler, George Springer and Alex Presley all on the disabled list.
"Marwin's hamstring is a concern of mine," Porter said. "Watching him run around and knowing he's not 100 percent, he's doing the best he can to get out there and gut it out and play. But it's something we have to be very mindful of and not blow his hamstring, and now you're looking at a considerable amount of time being missed."
Gonzalez injured the hamstring running the bases Saturday in Chicago and said Wednesday night he wasn't at 100 percent. The last thing the Astros need is another position player on the DL.
"You just pray that we're able to get healthy here soon and get some of these guys back and get some of these guys feeling better," Porter said.
