Trio of relievers unavailable due to injuries

NEW YORK -- David Robertson, Boone Logan and Shawn Kelley have been integral parts of the Yankees' bullpen all season, but with 21 games remaining and the playoff race heating up, all of them are unavailable with injuries.

Logan left Friday's game after feeling something in his elbow, and an MRI taken on Saturday revealed he had inflammation in the area. Robertson was diagnosed with shoulder tendinitis on Friday and will be out for a few more days, and Kelley has been sidelined since Sunday with inflammation in his triceps.

Kelley is the closest to returning. The right-hander threw 12 to 15 fastballs and sliders in a bullpen session on Saturday and said his arm felt good, "better than it probably has in a few months, actually."

Kelley thinks he'll be available to pitch on Sunday, but said he'll attempt to convince the Yankees he's ready to get back out there on Saturday.

"I'll lobby for it," Kelley said, laughing. "Probably to no avail."

Robertson said he felt better on Saturday than he did on Friday. He plans to take another day or two off, then play catch, throw a light bullpen session and try to return sometime next week.

"I didn't feel anything pop or tear or anything like that. I just know when I got in here [after Thursday's game], I was pretty fatigued and sore," Robertson said. "I reached back for a little extra on some pitches, and my shoulder just didn't feel good the next day."
