ST. PETERSBURG, Fla. -- Baltimore Orioles second baseman Brian Roberts will undergo an MRI after injuring his right hamstring while stealing second base in the ninth inning of Thursday's 6-3 victory over the Tampa Bay Rays.
Roberts, limited to 17 games because of injuries last season, said he felt something pop behind his right knee during his last couple steps to the base.
Manager Buck Showalter said the infielder will be reassessed Friday in Baltimore, where the Orioles play their home opener against Minnesota.
Roberts was noticeably favoring his leg walking in the clubhouse after the game. He said he wasn't sure how serious the injury might be, adding "we'll just wait and gather some information."
