Mark DeRosa injured again; Giants seriously lacking infield depth

In the fourth inning of tonight's Giants-Dodgers game, during an at-bat against Clayton Kershaw, Mark DeRosa incurred a left wrist strain. He's said to be day-to-day, but given his history of wrist problems, there's reason to believe he won't ever fully recover...

This is the latest in a series of injuries that have hurt the Giants. Pablo Sandoval recently had surgery to remove a portion of his broken hamate bone, and Freddy Sanchez had been ailing earlier, though he started at second base in tonight's game. Emmanuel Burriss and Ryan Rohlinger were optioned on May 10, meaning they have to spend ten days in the minors before they can be called up; and Conor Gillaspie sprained his ankle yesterday. 

Right now, it's looking like Mike Fontenot and Miguel Tejada will be starting on the left side of the infield, with (presumably) Aubrey Huff, or maybe even Nate Schierholtz, as backup third basemen.

UPDATE: Mark DeRosa is headed to the DL. The Giants will most likely call up Emmanuel Burriss or Ryan Rohlinger (there's an exception to the ten-day rule for injuries).
