Sandoval was out of the lineup on Sunday after he suffered a bruised elbow as a result of getting hit by a pitch in Saturday's game against the Seattle Mariners. X-rays were negative on the injury, according to the Providence Journal's Tim Britton.
This wasn't the first time an errant pitch has put the Red Sox third baseman out of commission this season; he missed five games from May 19-25 after being hit by a pitch in the knee.
Missing time is nothing new for Sandoval, who missed 99 games between the 2011 and 2012 seasons with the San Francisco Giants, as Bleacher Report's Adam Wells noted.
Sandoval is a legitimate power threat, but he has struggled to find his form in his debut season at Fenway Park. He's hitting just .259 with 10 home runs and 39 RBI, as the Red Sox sit in the AL East cellar, 12.5 games back of the division-leading New York Yankees.
