Rockies shortstop Troy Tulowitzki, who had returned from the DL only three weeks ago after missing 46 games, suffered a bad cut on his right hand after slamming his maple bat to the ground in frustration.
Tulowitzki took responsibility for the incident, calling it a "stupid injury that I could have prevented."
His regret is of little comfort to the Rockies who will be without their starting shortstop for an estimated two weeks.
This is only the latest in a long line of freak injuries for Rockies players. In 2005, second baseman Clint Barmes broke his collarbone in a fall while carrying a large slab of meat given to him by teammate Todd Helton up the stairs in his apartment building.
