The Philadelphia Phillies reinstated right-hander Taijuan Walker from the 15-day injured list on Tuesday.
Walker, celebrating his 32nd birthday, will start Tuesday night's game against the visiting Miami Marlins.
Walker (3-3, 5.60 ERA) landed on the injured list June 23 with inflammation in his right index finger.
The Phillies optioned right-hander Yunior Marte to Triple-A Lehigh Valley in a corresponding transaction.
