"Hey, Milner," Wathan said. "You're going to The Show. And you can take your roommate with you."
The Phillies promoted Milner and Perkins to replace outfielder Michael Saunders and right-hander Jeanmar Gomez, who were designated for assignment on Tuesday.
Milner, 26, took an interesting route to the big leagues. The Phillies turned the left-hander into a reliever in 2015, only to suggest later that he try throwing sidearm to save his career.
It worked.
Milner went 5-4 with a 2.77 ERA in 49 appearances with Double-A Reading and Lehigh Valley in 2016.
