You just don't see injuries like this in baseball very often: Sean Casey will miss the next six to eight weeks with two fractures in his left lower back. From ESPN:
Casey took several strides toward the pitcher's mound with the ball before dropping to his knees in obvious pain. He was assisted off the field and needed help getting to the Pirates' clubhouse before being taken to a hospital for tests.
"He had a shooting pain that was really bothering him," Pirates manager Jim Tracy said.
The fractures occurred in an area of the lower back where the muscles attach to the vertebrae, but the 31-year-old Casey isn't expected to undergo surgery. He was injured in his first game back after missing three starts with a bruised rib.
With Casey out, first baseman-outfielder Craig Wilson is expected to get most of the playing time. Wilson, even in a platoon role to start the season, had a team-leading five home runs entering the game against the Cubs on Saturday.
As it turns out, I had already picked up Wilson (as a replacement for Aubrey Huff) in a mixed league last night, so he's obviously a solid pickup in any mixed or NL-only league today. Watch out for Wilson's batting average -- it's good right now, but he can be streaky -- but he will definitely offer some nice power.
