"If you can throw 95, 96 [mph] at 10:30 in the morning, usually it should be OK," Chamberlain said. "It's one of those things where we wanted to make sure in between the innings, see how it reacted, just in case that would happen. I feel great."
Yankees manager Joe Girardi said that the team's plan is to restore Chamberlain to his seventh-inning role in the bullpen, and could also use him in the eighth inning on days that David Robertson needs rest.
Girardi indicated that Chamberlain's return would supplement a group that has also received contributions from right-handers Shawn Kelley and Preston Claiborne.
"It just gives us more depth," Girardi said. "With a lot of the close games that we've been in, it's good to have another power arm like that [to] share the workload with."
