PHILADELPHIA -- The Los Angeles Dodgers added two starting pitchers before last week's trade deadline in part so they could stash Mike Bolsinger at Triple-A, giving them some protection against another injury to their starting rotation.

That plan could be in jeopardy now, because Bolsinger left his Tuesday night start at Triple-A Oklahoma City after three innings after he was hit on the forearm by a pitch, according to the minor league team's Twitter feed. The Oklahoma City game notes say Bolsinger left the game with an "apparent injury," and was replaced by David Huff. Bolsinger had a 2.83 ERA in 16 starts for the Dodgers this season, though he averaged barely more than 5 1/3 innings per outing.

Dodgers general manager Farhan Zaidi did not immediately return a text message asking about the severity of Bolsinger's injury.

Alex Wood, acquired from the Atlanta Braves, made his Dodgers debut in Philadelphia Tuesday, allowing four runs in 6 1/3 innings. Mat Latos, acquired from the Miami Marlins, gave up one run in six innings on Saturday.
