According to the San Francisco Chronicle Oakland A's beat writer Susan Slusser, A's third baseman Scott Sizemore has suffered a left knee injury within the first hour of team's first full-squad workout. Slusser says that Sizemore is getting an MRI today to asses the damage to his knee, and according to an onlooker, there was "an audible pop" when the third baseman planted his foot. It is currently unclear exactly how Sizemore injured his knee and what the extent of the damage is, if any, but Slusser did say on her Twitter account that he appeared to be in significant pain.
Sizemore, who was acquired via trade from the Detroit Tigers in 2011, finished the season for the A's with .249 batting average, 76 hits and 42 runs including 11 home runs in 93 games. If his knee injury proves to be one that would keep him out for an extended period of time, his primary backups, Eric Sogard and Adam Rosales, could get some playing time, though Slusser believes that the A's would be more likely to look outside the organization for a replacement at third base.
