UPDATE: Joe Stiglich of the Contra Costa Times reports that the preliminary diagnosis is a left knee sprain, though we’ll learn more once the MRI results are known.
3:15 PM: Bad news from A’s camp.
According to Susan Slusser of the San Francisco Chronicle, Scott Sizemore appeared to be in “significant pain” after tweaking his knee during a fielding drill this afternoon.
In fact, one onlooker told Slusser that they could hear an audible “pop” sound at the time of the injury. The team has yet to provide an official update on Sizemore’s status.
Sizemore, 27, was acquired from the Tigers last May for left-hander David Purcey and batted .249/.345/.433 with 11 home runs, 52 RBI, four stolen bases and a .778 OPS over 93 games with Oakland while serving as the primary third baseman. If the injury is significant, the A’s would likely have to go with some combination of Adam Rosales or Eric Sogard at the hot corner.
