Joba Chamberlain's rehab hit a snag, though not one that Joe Girardi was ready to call significant. "He's just not quite ready yet," he said.
Chamberlain, on the disabled list with a right oblique strain, pitched in a rehab game Tuesday night for Triple-A Scranton. The expectation was he could be ready to return by Thursday night, but that wasn't the case. Instead, Girardi said, Chamberlain will play catch and "we'll go from there," which probably will include another rehab outing.

"Rib cages are tricky," Girardi said. "A lot of times you'll see where guys can throw or swing but you don't feel they're at 100 percent full power. We don't think he's quite there yet, so we're going to make sure he's ready."
Good news on Jeter
Derek Jeter, recovering from left ankle surgery, received good news from his doctor. "It's healing," Girardi said. "I think he'll be out of the boot sometime shortly and we'll go from there."
