The last time Joba Chamberlain made news, he was being shushed by Mariano Rivera. Tuesday, the hard-throwing reliever was activated from the disabled list, giving him a chance to make some noise with his arm for the first time in a month.

Chamberlain missed exactly a month with a strained right oblique, an injury he suffered while warming up in the bullpen on April 30. Unlike a minor oblique issue he had a few years ago, this injury took significantly longer to heal than Chamberlain hoped it would. “It kind of just depends on the situation, and everyone reacts different,” Chamberlain said. “I’d rather get it done and over with now, than have it linger and have to fight and battle through it all year.”

Chamberlain appeared in 10 games in April, allowing four runs on 10 hits and six walks over 9.1 innings, striking out seven. Those numbers are deceptive, however, as all four of his runs and four of his six walks came in his first two appearances.

In his final eight outings before landing on the DL, Chamberlain didn’t allow a run over 7.2 innings, emerging as the clear-cut favorite in the seventh inning.

That may change upon his return, as Shawn Kelley and Preston Claiborne have both pitched well during his absence.

“I anticipate Joba getting there,” Joe Girardi said. “We’ll see how we use him right away. Sometimes when a guy comes back from an injury, you want to work him back slowly. We’ll see what the opportunity is.”
