Crosby hopes to return in four to six weeks, and though he hasn't seen a hand specialist yet, he said early indications from the X-rays were that surgery wouldn't be required. Still, it was a major letdown considering he missed 132 games to injury combined in 2005 and 2006 but finally seemed healthy this season.
"I don't know what to say. I did all I could in the offseason and during the season to stay healthy," he said. "It got worse and worse. I knew last night when I couldn't pick up anything, I couldn't hold anything, I knew at that point it was broken."
His injury, combined with the fact that third baseman Eric Chavez is still unavailable with a sore lower back, leaves the A's without their starters on the left side of the infield.
Marco Scutaro will continue to start at third base and Donnie Murphy was called up from Triple-A Sacramento and penciled in to start at shortstop Wednesday afternoon against the Angels.
