The right-hander was back with the big league team Thursday after he was recalled from Triple-A Scranton/Wilkes-Barre following Wednesday night's win over the Blue Jays.
"We've seen the last couple of weeks, there were times we would use him," Yankees manager Joe Girardi said of Phelps in key spots. "Some of our guys down there are mix-and-match. Sometimes they've thrown a couple of days in a row where, Cory [Wade] was that guy for the last year for us, that you would go to and I'd say, 'I need five outs from him. I don't want to mix and match today because I've used these guys too much.' Here's a guy that I feel you can do it with."
Phelps, 25, is 1-3 with a 3.05 ERA in 15 games (three starts) this season. Girardi said he wants to use Phelps more frequently than he would a long man, but Phelps could nonetheless pitch two innings. Phelps also serves as rotation insurance.
