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."
Yanks: Consider Jeter day to day for rest of '13
BALTIMORE -- Yankees captain Derek Jeter remained in a "holding pattern" on Tuesday, according to manager Joe Girardi, and did not participate in baseball activities for a third consecutive day.
Jeter is continuing to receive treatment on a sore left ankle, and the Yankees have given no timetable for Jeter's return to the lineup. He was removed from Saturday's 13-9 loss to the Red Sox and had a CT scan, which was negative.
"I think he's making progress, but we just feel like it's not time yet," Girardi said.
Jeter, who is batting .190 with one home run and seven RBIs in 17 games this season, has not spoken publicly since before Saturday's game.
Yankees general manager Brian Cashman said that the club is still waiting to hear back from Dr. Robert Anderson, the Charlotte, N.C.-based specialist who performed Jeter's October ankle surgery.
Anderson has been sent a copy of Jeter's CT scan for review, but Cashman said that Anderson's diagnosis was not holding up the Yankees in any way because they are confident in team physician Dr. Christopher Ahmad's assessment.
"The bottom line is, his mobility was definitely becoming more limited with the pain he was receiving, so we backed off," Cashman said. "And when he's feeling better, we'll turn him loose again."
Girardi said that Jeter, who typically detests missing games, understands that he needs to rest in order to allow his ankle to get stronger and feel better.
He added that it is "fair to say" that the Yankees will consider Jeter day to day for the rest of the season, and cannot say for sure if Jeter actually will return.
"It's just hard, because we want him to feel good about going out there and not having some pain -- being able to move the way we need him to move and the way he wants to move," Girardi said.
Cashman reiterated that there has been no consideration given to shutting Jeter down for the year.
"We don't think that. It's nothing like that," Cashman said. "If it becomes that, I'll tell you, but otherwise we're more in a day-to-day mode."
Robertson progresses, hopes to return this week
BALTIMORE -- David Robertson threw 11 pitches in the bullpen on Tuesday and reported no issues with his pitching shoulder, giving the Yankees reliever optimism that he will soon be able to return to duty.
Robertson has not pitched since Sept. 5, and said that though he feels he could probably pitch on Tuesday, the right-hander expects the Yankees to rest him until Wednesday against the Orioles, at the earliest.
"I understand why they want to give me the extra day. They don't want to rush me back out there," Robertson said. "Today was a good step forward. I threw a bullpen, cut the ball loose and didn't have any problems."
Robertson is 4-1 with a 1.85 ERA in 61 appearances this season.
"I just needed a few days," he said. "I needed to get some strength back in my shoulder before I went out and pitched. I didn't want to go out there, stink in a game and get injured, something like that."
• The Yankees continue to plan to start Huff on Thursday, assuming they do not need to use him in relief on Tuesday or Wednesday, Girardi said.
• Chris Stewart returned to the Yankees' lineup Tuesday after missing Monday's game with a bruised left foot. Stewart was hit by a pitch in Sunday's 4-3 win over the Red Sox.
• On this date in 1922, the Yankees played their final regular-season game at the Polo Grounds, defeating the Philadelphia Athletics, 2-1.
