Orioles shortstop J.J. Hardy will undergo an MRI on his left oblique on Monday. Early indications have the team fearing they could be without him for up to six weeks. "It's not good," former Brewers teammate Corey Hart said of Hardy's diagnosis. "They thought mine was going to be minor, and here we are six weeks later. Maybe I'm not a quick healer. It's a tough thing -- you try to push it and all of a sudden you're pushed back three days. It's crazy how everybody is getting them." In six games, Hardy is hitting .200 with an OPS of .294.
