In case you weren’t convinced by the fact that he has a locker in the Yankees clubhouse, held an 11-minute “welcome to the team” interview session and is in tonight’s lineup against the Astros, it’s now really, really official — Vernon Wells has been acquired by the Yankees from the Angels.

Here’s the breakdown from the Yankees’ press release, and there will be more to come later on yankees.com.

“The New York Yankees today announced they acquired three-time All-Star and three-time Gold Glove Award-winning outfielder Vernon Wells along with cash considerations from the Los Angeles Angels in exchange for minor league outfielder Exircado Cayones and minor league left-handed pitcher Kramer Sneed.”

The Yankees said that a reciprocal 40-man roster move will be announced at a later time.

Derek Jeter’s surgically repaired left ankle was too sore to play in a Minor League game today and he will rest for the next two days, according to general manager Brian Cashman, who said it is looking more and more realistic that the Yankees shortstop will need to begin the year on the disabled list.

Cashman said that the reality of the situation is beginning to sink in to Jeter and that April 6 is being looked at as the new goal to get Jeter in a big league game. Cashman said that the Yankees need to see Jeter being able to play every day without discomfort and as a shortstop before they would have him on the active roster.

“We’ll obviously just have to continue to respond to how he feels,” Cashman said. “I think he felt really good from the [cortisone] shot, but this continues to tell you that it’s just not ready yet for the full duties. Obviously it’s looking more likely than not that he will start the season on the DL and a more realistic goal is April 6th.”

The Yankees have not fielded an Opening Day lineup without Jeter since 2001, when Luis Sojo filled in at shortstop while Jeter was mending a quadriceps injury. Cashman said that the Yankees can go with Eduardo Nunez at shortstop until Jeter returns.

Derek Jeter will not appear in another Grapefruit League game this spring, according to general manager Brian Cashman, because the Yankees want to be able to backdate his injury if the shortstop must begin the year on the disabled list.

Jeter will be limited to playing in Minor League games for the rest of the Yankees’ time in Spring Training. Jeter is still hopeful that he will be able to play on Opening Day, but if not, the Yankees can set the captain’s earliest return for April 6 at Detroit.

“I think we need to preserve the ability to backdate him in the event that he’s not going to make it,” Cashman said.

Teams can backdate the disabled list assignments of injured players to a date 10 days prior to the season opener. If that were to happen in Jeter’s case, he would be eligible to be activated five days (four games) into the season.

Jeter, 38, had a cortisone injection in his surgically repaired left ankle on Wednesday and is expected to be unable to play for at least a few days, though he said on Thursday that if this were the regular season, he’d fight to be in the lineup.

“If it ain’t broke, you can play,” Jeter said. “So yeah, if I had to play, I would play.”

The Yankees made the short trip this morning to Clearwater, where Derek Jeter was scheduled to start at shortstop for the fourth time this spring. But he had some trouble loosening up the area around his surgically repaired left ankle and was scratched from New York’s lineup after taking batting practice.

Before heading back to Tampa, Jeter reiterated what he said a few hours earlier in the Yankees’ clubhouse at George M. Steinbrenner Field: He was told that the area around his left ankle would be stiff and sore. Today, he said the “front” of his ankle was just a little stiffer than usual.

“Maybe if I wasn’t told it was going to happen, then I would be concerned. But from everything that I’ve been told from the doctors, it’s normal,” Jeter said. ”It’s just stiff. Stiffness. But once again, it’s not in the part that I broke. It’s just around there. That’s why I’m not concerned.”

Jeter termed this an “old-fashioned day-to-day” situation and said he could return to the lineup as soon as Wednesday.

“I wish I had an answer for you, but I don’t know. I’ll play as soon as I can,” Jeter said. “If I can play tomorrow, I’ll play tomorrow. If it’s the next day, it’s the next day. The luxury is it is spring training. Two weeks is plenty of time to get ready.”

TAMPA, Fla. — Yankees third baseman Ronnier Mustelier was forced to leave Friday’s game against the Marlins after colliding with a metal railing in pursuit of a foul ball.

Mustelier was chasing Juan Pierre’s fourth-inning pop-up when he hit the fence in front of the third base camera well, falling to the ground. He was helped to his feet by manager Joe Girardi and head athletic trainer Steve Donohue and walked off the field slowly.

The Yankees announced that Mustelier suffered multiple contusions to both legs, and said that further evaluations are to come.

Yankees general manager Brian Cashman has said that Mustelier’s live bat was giving him a chance to make the roster this spring, as the team searches for possible replacements for injured stars Curtis Granderson and Mark Teixeira.

A 28-year-old from Cuba who has played mostly outfield in the Yankees’ Minor League system, Mustelier has received more of a look at third base of late, with Kevin Youkilis playing some first base.

Mustelier also was involved in a scary outfield crash earlier in camp, colliding with prospect Slade Heathcott in right-center field as they chased a fly ball. Mustelier caught the ball and emerged unscathed, while Heathcott sprained his thumb.

Here at Florida Auto Exchange Stadium, right-hander David Phelps will make his fourth start of the spring. He’s still fighting for a spot in the Yankees’ rotation, a battle with Ivan Nova that has flown somewhat under the radar. 

“They’re both throwing pretty well. When I look at them, they’ve done everything that we wanted them to do,” Yankees manager Joe Girardi said this morning. “Phelps’ command has been very good. Nova’s command has been good. His curveball’s been excellent. They’ve both pitched well. It is an interesting competition, and we believe [Phil Hughes is] probably going to be ready, but it could become a moot point if he’s not.”

Adam Berry here, filling in for Bryan Hoch. I was told the big story today would be Phil Hughes and David Robertson throwing in the bullpen. For more updates from Yankees camp, check out Yankees.com or follow me on Twitter @adamdberry.

Mariano Rivera walked into the pavilion just outside George M. Steinbrenner Field, closely followed by Andy Pettitte and Derek Jeter and the entire Yankees team. He took his seat at a table in front of the assembled media, next to his wife, Clara, and two of his three sons, Jafet and Jaziel, with Yankees managing general partner Hal Steinbrenner and GM Brian Cashman nearby.

He opened with a joke.

“I would like to start by thanking Cashman for breaking his policy of giving extensions to a player. Thank you, Cashman, for giving me a two-year extension for 2014 and ’15,” Rivera said. “I know it’s your policy, but we need to start doing that. Cash, thank you, man. I appreciate that.”

The crowd responded with a laugh, then Rivera got to what everyone knew he was there for, officially announcing that he will retire after the 2013 season, bringing an end to his illustrious and storied career. He would have done so at the end of last year, he said, had he been able to finish the season healthy.

“Why now? Now is the time. Now is the time,” Rivera said. “I have given everything, and the time is almost ending. The thing that I have, the little gas I have left is everything for this year. After that, I’ll empty everything. There’s nothing left. I did everything and I’m proud of it. That’s why it’s time.

“I’m telling you the tank is empty. I think that’s enough. It’s been a journey. One thing I will say, that I will never stop missing the game or the action on the field and my teammates. After that, it’s nothing else. The traveling, hotels and all that, there’s no more in me. I’ll do what I have to do next.”

As for what’s next, Rivera said he wants to spend time with his family and go on a “long vacation” when he’s done playing, but he wants to stay involved in the game by working with Minor League players. 

Rivera said he knew when he came to Spring Training that he was going to make this announcement. He told the team’s ownership, Cashman, Girardi and a few of his teammates. 

He wanted Saturday to be a day of “celebrating,” not sadness. He wants to say goodbye to each city’s fans on what will quickly become the Mariano Rivera Farewell Tour this season, and the Yankees are helping him find and thank “special people in the game” who share his passion for baseball.

He said he wants to be remembered as a team player, someone who was there for others without thinking of himself. And under what circumstances does he want to make the last pitch of his career?

“The last game I hope will be throwing the last pitch in the World Series. That’s how I envision to be my last game of my last pitch on the mound,” Rivera said. “Winning the World Series, that would be my ambition.”
