PHILADELPHIA -- The Phillies and Cubs will play a single-admission doubleheader Friday at Citizens Bank Park.

Rain postponed Thursday night's series opener between the two teams. The doubleheader will begin at 5:05 p.m. ET. Phillies left-hander Adam Morgan (5-5, 4.42 ERA) will face Cubs right-hander Jake Arrieta (18-6, 2.03 ERA) in Game 1. Phillies right-hander Alec Asher (0-2, 10.61 ERA) gets the start opposite Cubs right-hander Kyle Hendricks (6-6, 4.08 ERA) in Game 2.

Fans holding tickets to Thursday's game may exchange them for tickets to any remaining Phillies home game this season, including Friday's doubleheader. The tickets may also be exchanged for any 2016 home game, when single game tickets go on sale in February. Exchanges should occur by May 31, 2016.
