Devastating news here. Losing a .320 hitter, our best hitter with RISP and our only true SS on the roster is just awful. I doubt Janish is called-up to start so we might very well see Hairston moved to SS... which I am not looking forward to considering how strong Kepp has been out there with the glove.Keppinger appeared to hurt himself in the second inning when he fouled a ball off the inside of his leg. Corey Patterson pinch hit for him in the fourth. In the fifth, Jerry Hairston Jr. moved to short stop, Ryan Freel moved to right field, and Patterson moved to center field.
UPDATE: An X-ray revealed that Keppinger fractured the patella in his left knee. He will have an MRI tomorrow.
