Jeter slotted at DH; Nunez starts at short

NEW YORK -- About the only thing Derek Jeter detests discussing more than a future away from the Yankees organization is injuries; in this case, the lingering bone bruise on his left ankle.

"[It feels] great," Jeter said on Friday, echoing what he has been telling manager Joe Girardi for some time.

Still, Girardi opted to use Jeter as the Yankees' designated hitter on Friday, offering him a half-day of rest as the Yankees opened a three-game series against the Athletics. Eduardo Nunez was tabbed to start at shortstop.

"It's something that we're going to have to manage," Girardi said. "It's not 100 percent. You could say, why don't you give him a week off? I'm not so sure it'd be 100 percent if you gave him a week off. We'll have to manage it. I'm going to pick my days and just kind of go day by day."

Girardi said that there was nothing in particular from Thursday's 10-7 victory over the Blue Jays that made him decide to keep Jeter out of the field on Friday.

"You have to pick your times," Girardi said. "He said he feels better but, as I said, it's not 100 percent. I know that. He knows that. He'll never admit that, but you've got to pick your times to [rest] it."

Jeter not wearing Yankees pinstripes 'comical'

NEW YORK -- Derek Jeter said on Friday that it seems "comical" to suggest that he would want to finish his career anywhere else than with the Yankees, going on to clarify comments that the captain recently made in a published interview.

Jeter said that he told ESPN's Rick Reilly that he could see himself playing for another franchise, the way Peyton Manning parted ways with the NFL's Indianapolis Colts and latched on with the Denver Broncos, if the Yankees decided that they no longer wanted him.

"You understand what the reference is: Peyton had no choice, so if he's going to continue to play, he's got to go somewhere else," Jeter said. "I think it's comical that we're talking about it after I've told you guys time and time again that I can't picture myself playing anywhere else. Have fun with it."

The New York Daily News nodded to Reilly's Q & A for a front page splash on Friday, blaring a large type headline, "Say What!"

But Jeter, who signed a three-year, $51 million deal after the 2010 season that includes a player option for the 2014 season, said he has no intention of packing his bags.

"It seems pretty obvious though, when you're talking about that situation, what I'm talking about," Jeter said. "It's a business. There's two sides to a business. That's what the reference was."

Alex Rodriguez said that he can't imagine Jeter ending his illustrious career with anyone but the Yankees.

"That'll never happen," Rodriguez said. "I never see Derek playing in [another] uniform. I see him, forever, for the next 1,000 years, in pinstripes. Even when he's 50 or 60, who knows, he'll still be helping out and being a leader and captain to the Yankee franchise."

The negotiations between Jeter and the Yankees grew contentious for that last deal, following a 2010 season in which Jeter batted a career-low .270, but Jeter said that the situation never changed the stance that he wanted to finish his career with the Yankees.

"That's what I've told you my whole focus has been since day one," Jeter said. "Why are we even talking about this?"

Bombers bits

• The Yankees have not yet activated Brett Gardner for pinch-running duty, though manager Joe Girardi said that their intention is still to do so before the end of the season.

"Nothing yet," Girardi said. "I keep saying, it's going to happen, it's going to happen. I just can't tell you exactly what date. ... I don't really want to get into it. We're just not quite ready to make the move."

 • Girardi said that the Yankees expect Andy Pettitte to be ready to throw 85 to 90 pitches in his next scheduled start on Monday against the Twins at Target Field. David Phelps would also likely be available if needed in long relief that day.

 • On this date in 1955, boxer Rocky Marciano knocked out Archie Moore in the ninth round, retaining his world heavyweight title in a bout held at Yankee Stadium.
