Phillies outfielder Bryce Harper will undergo elbow surgery. His timeframe for return is currently undecided. Harper injured his elbow on a throw in April. He missed about a month. When he came back into the lineup he could only DH. The former MVP was able to continue hitting at a high level even with his throwing arm damaged. Harper was playing well until he broke his thumb in June against the Padres. This injury prevented him from hitting and took him out of the lineup completely.
