BALTIMORE -- Yankees left-hander Boone Logan has seen no improvement in his sore left arm following a cortisone injection, and the club is preparing to send his medical records to Dr. James Andrews in Pensacola, Fla., for further evaluation.
Logan felt discomfort near his pitching elbow in a Sept. 6 outing against the Red Sox and had an MRI, which the Yankees said showed inflammation. General manager Brian Cashman said that Logan had requested Andrews see his results.
"He's still stuck at zero," Cashman said of Logan. "I don't think he's made any progress."
Because of Logan's uncertain situation, Cashman signed free agent left-hander Mike Zagurski. The 30-year-old posted a 3.08 ERA in 26 1/3 innings at Triple-A Scranton/Wilkes-Barre this season before opting out of his Minor League contract.
He pitched in six games this season for the Pirates and had been with the Athletics organization before opting out on Sept. 2. Cashman said the Yankees wanted another lefty to join David Huff on New York's staff.
"It's concern enough that we decided, let's go get another lefty reliever and try to give [manager] Joe Girardi as many weapons as possible to match up late in the game," Cashman said.
In a corresponding roster move, the Yankees transferred designated hitter Travis Hafner to the 60-day disabled list. Cashman said that though Hafner technically could return for the last series of the year against the Astros, it would be "an outside shot."
