Jeter gradually ramping up spring workouts

TAMPA, Fla. -- On the eve of the Yankees' first Grapefruit League game, Derek Jeter provided a brief update on his progress as he works his way back from offseason surgery on his left ankle.

Jeter has been taking regular batting practice and taking ground balls with the rest of his teammates, but he still has not run the bases. He doesn't know exactly when he'll begin doing so, but he has been running indoors, as he's on a different workout program than the rest of the team.

Jeter has been doing more agility drills and more running, gradually ramping up his workouts the same way he'd do any other year.

"I've been stepping it up every day," Jeter said. "Every day is more and more. I've been increasing the workload since I started."

Jeter has said several times that he will be ready to start come Opening Day, and he repeated that on Friday.

"You have to be smart. ... We've still got close to 40 days," he said. "There's no reason for me to go out there and jump all around and do things that I shouldn't be doing at this particular point."

Girardi sets travel roster for Grapefruit opener

TAMPA, Fla. -- The Yankees have set their travel roster for Saturday's Grapefruit League opener, against the Braves in Lake Buena Vista. As manager Joe Girardi said on Thursday, the starting lineup will include first baseman Mark Teixeira, second baseman Robinson Cano and infielder Eduardo Nunez behind starter David Phelps.

Catchers Francisco Cervelli and Austin Romine, both battling -- along with Chris Stewart -- for two spots on the roster, will make the trip, with Cervelli getting the start. Also hopping on the bus will be outfield candidates Juan Rivera and Matt Diaz, and corner infielder Dan Johnson.

Phelps is expected to throw two innings or 35 pitches, and he will be followed in some order by right-handers Brett Marshall, Mike O'Brien, Kelvin Perez, Branden Pinder and Chase Whitley, and left-hander Nik Turley.

Girardi is eager to see Cervelli and Romine finally get behind the plate in a game situation. He admitted earlier this week that they couldn't do much to put themselves in position to win a roster spot in drills, although he cautioned once again that he won't judge their performances too closely this soon.

"You want to see the competition," Girardi said. "They've got to get their bodies physically in shape. They've got to get their timing down offensively, get to know the pitchers. They're going to catch a lot of pitchers early on that they don't know."

Jay-Z, Timberlake to perform at Stadium in July

TAMPA, Fla. -- Jay-Z and Justin Timberlake announced a summer tour on Friday that will bring them to Yankee Stadium on July 19.

The "Legends of the Summer" stadium tour will visit 12 cities in North America, with the first stop at Rogers Centre in Toronto on July 17. The tour will visit, among other locations, Chicago, San Francisco, Baltimore and Boston before wrapping up on Aug. 16 at Sun Life Stadium in Miami.

Tickets for the shows, save the Yankee Stadium performance, will go on sale to the public on Thursday at LiveNation.com. The on-sale information for the New York show will be announced soon, according to a LiveNation release announcing the tour.

Bombers bits

• Right-hander Phil Hughes said on Friday he is "way better" and noticed a "significant" difference in the way his back feels compared with earlier in the week, when he was sidelined with a bulging disk in his upper back. Hughes expects to finish his anti-inflammatory medication over the next two days and perhaps begin working out in a pool as early as Sunday.

"I think you've got to see him get on the mound to feel that you're through it and that it's not going to be an issue that pops up all the time," manager Joe Girardi said. "I think we have to see him get on the mound, but that's a good sign."

• CC Sabathia threw another bullpen session and Andy Pettitte pitched batting practice on Friday morning, and Girardi reported that both outings -- as well as right-hander David Robertson's BP session -- went well.

• Having previously announced that right-handers David Phelps and Adam Warren will start the Yankees' first two Grapefruit League games, Girardi said on Friday that lefty Vidal Nuno and right-hander Jose Ramirez will start the next two.
