Marlins pitcher Anthony DeSclafani was forced to leave his start against the Athletics Friday, after taking a ball off his right forearm.

DeSclafani took a line drive off his arm during the third inning, and was replaced by a reliever to start the fourth. He was diagnosed with a right forearm contusion, and the team says he is officially listed as day to day.

DeSclafani was charged with two runs on five hits in three innings, while striking out two batters before leaving the game. His ERA fell slightly, to 7.40 in the game, with his next start scheduled for Thursday against the Phillies.
