"It felt amazing to get out there today," Aardsma tweeted. "Threw well, but the job isn't done. Need to #keepworking if I want to get to the #yankees."
The Yankees signed Aardsma in February, knowing he would start the season on the disabled list after undergoing Tommy John surgery last July. Aardsma tweeted he would pitch again Saturday for the GCL Yankees, but manager Joe Girardi is unsure of when the reliever could join the team in New York.
"I have not been given a time frame on him," Girardi said, "but obviously, he's a lot closer than when we left."
Although neither Aardsma nor Joba Chamberlain have specific time frames to return from their injuries, Girardi envisions both joining the bullpen at some point this season. Starter Michael Pineda, who will not return from his shoulder surgery this year, is rehabbing with Chamberlain in Tampa, Fla., and is impressed with the right-hander.
"He's been looking good," Pineda said. "I've seen a couple bullpens from this guy, and he looks good in the bullpen right now."
