Feliciano, who has been rehabbing from left rotator cuff surgery in Tampa, Fla., threw a bullpen session at Tropicana Field on Tuesday afternoon, and Girardi was impressed with what he saw.
"His ball was moving all over the place," Girardi said. "It had good sink to it. He threw a few sliders. He threw some changeups that really dove. It was good to see. He's encouraged; I'm encouraged. ... It's something we have to be careful [with] and we can't rush, but he looks pretty good."
The 35-year-old left-hander has been throwing in the bullpen once every three days, and the plan is to have him throw once every two days going forward. Could that put him on track to join the Yankees' bullpen at some point this season?
"I do think it's possible if he doesn't have any setbacks, yes," Girardi said. "He has such a serious injury, we weren't sure what was going to happen. If we thought he was done, we wouldn't have brought him to Spring Training."
Feliciano hasn't pitched in the Majors since October 2010, when he was with the Mets. For his career, Feliciano is 22-19 with a 3.31 ERA and 341 strikeouts in 372 1/3 innings.
