Lough can play all outfield positions and at a high level, having graded out at 3.1 DWAR in parts of 4 MLB seasons with the Royals and Orioles. His bat is less than ideal, but he's flashed promise here and there. In 312 games, he's posted a .255/.672 line, being buoyed by a solid 2013-2014.
He's going to have a difficult time cracking the Phillies 25-man roster, but could be a legitimate 5th outfielder option should the Phils trade Cody Asche. I am in favor of an Asche trade, because he is horrible defensively at both third base and left field. His bat is average and he is still young at 25, but I'd rather see other players getting playing time heading forward. Sending him packing for some sorta low level prospect might be what's best for Asche and the organization.
