Pomeranz (biceps) will start against the Orioles on Tuesday, Pete Abraham of The Boston Globe reports.
Pomeranz hasn't started a big-league game since May 31 in Houston as he's spent the majority of the past two months recovering from left biceps tendinitis. He was able to partake in a sixth minor-league contest in recent days, tossing a tidy six innings for Triple-A Pawtucket. He will take the spot of Eduardo Rodriguez (ankle) in the rotation.
