Sosa was diagnosed with a left elbow contusion after being hit by a pitch in the fifth inning of Saturday's 12-1 win over the Diamondbacks, Brooke Destra of NBC Sports Philadelphia reports.
Though X-rays have cleared Sosa of a serious injury, he should be considered day-to-day heading into Sunday's series finale. He went 0-for-1 with a run scored prior to exiting.
