As expected, Joba Chamberlain is likely to rejoin the Yankees when the 30-day deadline on his rehab assignment runs out on Aug. 6. GM Brian Cashman told ESPNNewYork.com today that the right-handed reliever "has been doing great'' in his rehab starts and would be back with the team the first week of August if not sooner.

Earlier in the day, Cashman told WFAN, “Joba’s out of control. The stuff he’s featuring is remarkable. He’s as high as 100 (mph) but upwards consistently (at) 96, 97, 98. He looks really good.”

Chamberlain underwent both Tommy John surgery and an appendectomy last June, then had a setback in his recovery when he dislocated an ankle jumping on a trampoline with his young son in March.

“He’s an amazing guy,” Cashman said on WFAN. “He’s been hurt, he gets hurt a lot, but then his recovery time is like super-human -- always beats the standard. So yeah, he’s due back here shortly. I mean, the worst-case scenario would be the first week of August, but he should be here ahead of that.”
