SCOTTSDALE, Ariz. -- Cubs shortstop Starlin Castro underwent an MRI Friday on his left hamstring, which showed mild inflammation, and he was not expected back in action until mid-next week.
Castro had to leave last Wednesday's game after feeling some tightness in his hamstring running to first base. He was able to hit in the batting cage the next day but had an MRI Friday.
Cubs manager Dale Sveum had said Castro could be back in a game Monday, but now it seems more likely next Wednesday, at the earliest. The good news is Castro doesn't feel any pain in his leg now.
"I think we might be a little more cautious than normal," Sveum said Saturday. "We might see him on the field in three or four days."
Castro was expected to take ground balls on Sunday, and might do some running as well.
