NEW YORK -- Yankees right-hander David Robertson expects to pitch on Sunday for Triple-A Scranton/Wilkes-Barre and could rejoin the Yankees in Washington in a week.
Robertson said that he would anticipate making at least two Minor League rehabilitation appearances to hone his command coming back from a left oblique strain.
"I'm trying to make sure it's ready," said Robertson, who said he threw hard in a bullpen session on Thursday at Yankee Stadium. "The last thing I want to do is come back and say I'm fine and then have something else happen."
Yankees manager Joe Girardi said that he does not necessarily think Robertson would need to pitch in back-to-back games before he could be activated from the disabled list.
"We'll evaluate it after each one, see how he does," Girardi said. "I thought he threw OK [Thursday]. You've got to make sure that he has his command before he comes back, but it shouldn't be too many [appearances]."
Jeter feeds off unique energy of Subway Series
NEW YORK -- Derek Jeter has always done some of his best work against the Mets, so it is no stretch to think that the Yankees' captain feeds off the electricity of the Subway Series.
Jeter entered play on Friday with a career .381 batting average against the Mets, the highest all-time mark among players with a minimum of 150 plate appearances against the Bombers' crosstown rivals.
"I think the biggest thing is the atmosphere," Jeter said. "The fans get into it, whether it's here, the old Stadium, Shea Stadium or the new Mets stadium. The fans get into it. There's a lot of energy in the stadium, which makes it fun for us as players, regardless of what either teams' record is.
"It seems like the atmosphere is a little bit higher, similar to when we play Boston. The atmosphere is great, and that always makes it fun for us."
That is not to say that Jeter would be upset if Major League Baseball carries through on a proposal to reduce the Subway Series from six games, editing the Interleague schedule next season to accommodate the Astros' move to the American League. It is possible that the Mets and Yankees might meet just three times in 2013, and Jeter said he'd prefer to see the Yankees go back to playing only AL clubs.
"I've always been kind of old school anyway," Jeter said. "I liked it when you didn't even face the National League. When I first came up, that's how it was. You'd play in the World Series, or hopefully you'd play in the World Series, and you hadn't seen the team. I understand it's great for the fans getting an opportunity to see players they don't normally see, but I kind of like it the other way."
Jeter seems to be in the minority among his Yankees teammates. Mark Teixeira said he'd like to see the Mets and Yankees play at least three times each season, and manager Joe Girardi opined that three meetings would be a perfect number.
"I've always thought there should be only three because I think there should be a winner every year for sure," Girardi said. "I would actually be in favor of that."
Joba throws for first time since ankle injury
NEW YORK -- Yankees reliever Joba Chamberlain threw 25 pitches on Friday at the club's complex in Tampa, Fla., his first time on a mound since sustaining a right ankle injury in March.
"It felt good," Chamberlain told The Associated Press. "Another step forward. That's all you can do."
Chamberlain dislocated his right ankle bouncing on a trampoline with his son on March 22. He has also resumed running sprints in the outfield and told the AP he will pitch this season.
"Is that even a question?" he said.
David Aardsma threw 40 pitches during his third batting-practice session and might be ready to pitch in a simulated game late next week. Aardsma is recovering from Tommy John surgery performed last July.
Jeter said he is not concerned with his at-bats, despite a recent 0-for-13 stretch that saw him go hitless during the club's series against the Tampa Bay Rays.
"You just try to get comfortable again. It's not the first time. Sometimes all it takes is one at-bat," Jeter said.
Yankees outfielder Brett Gardner was set to play in a Minor League rehabilitation game for Class A Charleston on Friday. Gardner could rejoin the Yankees on Monday in Atlanta; he has not played in a Major League game since April 17.
The Empire State Building will be lit this weekend in the honor of the Subway Series, with its north/south sides in Yankees blue and white and its east/west sides lit in Mets orange and blue. The winner of the series will have its colors displayed on Monday.
On this date in 1969, Mickey Mantle Day was celebrated at Yankee Stadium as the Mick's No. 7 jersey was retired and a plaque was unveiled in his honor. The Yankees then swept a doubleheader from the White Sox by scores of 3-1 and 11-2.
