If Philadelphia defeats the Milwaukee Brewers Wednesday in Milwaukee, and the Atlanta Braves lose to the Cincinnati Reds, the Phillies will have secured a playoff spot for the third consecutive season. The Phillies haven't had a run of success like this since Philadelphia won five straight National League East titles between 2007 and 2011.

Philadelphia faces Milwaukee at 7:40 p.m., Wednesday at American Family Field. Philadelphia right-hander Aaron Nola (12-8, 3.62 ERA) will face Milwaukee right-hander Freddy Peralta (11-8, 3.75 ERA). The game will be on NBCSP and MLB Network for those out of market. The radio broadcast will be on 94WIP and WDEL 101.7 FM/1150 AM.
