NEW YORK -- Yankees left-hander Andy Pettitte has been dealt a setback as he attempts to return from a strained left groin, and will not throw off a mound again for approximately one week.
Pettitte threw approximately 40 pitches at Yankee Stadium before the Bombers' game Tuesday against the Tigers, and though he completed the session, Pettitte still has some hesitation to throw with full intensity.
A MRI exam taken Tuesday at New York's Columbia-Presbyterian Hospital revealed what the Yankees said is a "small, persistent strain" of Pettitte's left groin. Pettitte will continue throwing off flat ground, but will not set foot on a mound.
"I'm feeling good. I'm feeling better," Pettitte said before leaving Yankee Stadium. "But when I reach back 100 percent, like I'm trying to get a batter out in a game, the groin area grabs."
Pettitte has been on the 15-day disabled list since he strained the groin in a July 18 start against the Rays.
The veteran had been working out at the club's Minor League complex in Tampa, Fla., before rejoining the Yankees on Saturday in Kansas City. The initial diagnosis at the time of Pettitte's injury had been four to five weeks for a Major League return, but general manager Brian Cashman said that he does not have a definite timetable to expect Pettitte back.
"We've just got to give Andy the time he needs," Cashman said. "The time frame is taking longer than any of us would want, but it is what it is. We'll get him right and we'll get him ready, but we can't get it sooner than it'll be ready."
Cashman complimented the work that Dustin Moseley has done filling in for Pettitte in the rotation, while also mentioning that if they should need to dip into the farm system, right-hander Ivan Nova is knocking on the door for an opportunity at Triple-A Scranton/Wilkes-Barre. Cashman said that he does not foresee an August waiver-wire deal to bring in a starting pitcher.
"I don't anticipate any more moves," Cashman said. "I think this is the team we've got and we're looking forward to playing the string out and seeing where it takes us."
Low-grade strain keeping A-Rod day-to-day
NEW YORK -- An MRI exam revealed a low-level strain in a calf injury that forced Alex Rodriguez to sit out Tuesday's 6-2 win over the Tigers after leaving Monday's game early. Rodriguez is day-to-day, but does not expect to play Wednesday night, when the Yankees continue their four-game series against the Tigers.
Rodriguez said Tuesday he first felt something before Monday's game and received treatment. He then felt his calf worsen five steps out of the batter's box after his second plate appearance. He left the game after that.
"I have no idea right now," Rodriguez said when asked how long he would miss. "I feel surprisingly better than I thought. Hopefully, it's just a day-to-day thing."
The injury is similar to one sustained by catcher Jorge Posada earlier this season. Posada missed six games, but both Yankees general manager Brian Cashman and manager Joe Girardi seemed optimistic Rodriguez's version wasn't as bad.
"Everybody's different," Cashman said. "Posada had this, and he was about six days. This is not as significant as Posada's, as conveyed to me. It probably means less time -- doesn't mean it will be less time. It just depends. It's not a serious situation, but it's obviously serious in the case we don't have him."
"You got to treat the symptom, not what the expectation is," Girardi said. "He's day-to-day until he plays."
Rodriguez, who said he has never had a calf injury, suffered the injury days after a three-home run game against the Royals on Saturday.
"I'm not concerned," Rodriguez said when asked if the injury could derail his offensive momentum. "I'm going to be fine. I feel myself, our team, overall, we're going to have a good stretch here coming down the stretch."
Robinson Cano has moved up to bat cleanup from his usual No. 5 spot in the Yankees' order. Ramiro Pena has filled in at third base. On Tuesday, Cano went 1-for-4 with a walk and a home run, and Pena singled and hit a sacrifice fly in four plate appearances.
Girardi said it was too early to tell if Rodriguez would return as a designated hitter before he played the field.
"Obviously, if he can DH before he can play the field, that's something I'm definitely going to look at," Girardi said.
Rodriguez said the Yankees' medical staff described the MRI in a positive light and preached caution.
"Right now, we have really good news, and we don't want to prolong it or make it a serious situation," he said.
Swisher starts, vows to swing smarter
NEW YORK -- Nick Swisher has been living with a variation of tennis elbow for some time now, but the outfielder has no intention of allowing it to keep him out of the Yankees' lineup.
Swisher had to leave Monday's 3-1 loss to Detroit in the sixth inning with tightness in his right forearm, but he was back in the lineup for New York on Tuesday.
"I just have to be a little smarter," Swisher said. "I know it's late in the season and I just can't be taking all the swings that I would like to. I've got to work on that."
The switch-hitting Swisher especially feels the pain -- which he called a sharp "zing" -- when he extends his right elbow on an outside pitch, or swings hard and misses.
"He's better today," Yankees manager Joe Girardi said. "He's had this tennis elbow off and on for a while now. Really, the big thing is, don't swing and miss, and make sure you don't get the ball too far out front."
Glove mix-up has Cervelli with Wright's stuff
NEW YORK -- Francisco Cervelli backpedaled into foul territory down the third-base line Monday and put away a popup with relative ease. He may not play there every night, but at least he seemed to have the right equipment on hand.
The Yankees catcher took the field wearing a Wilson model glove that had "Wright No. 5" embroidered on the heel, appearing in play on the wrong side of the tracks from where the Mets' David Wright keeps his stuff stashed at Citi Field.
But there is an explanation how this glove wound up in the Bronx, Cervelli says, and the tale probably started with a mix-up in a Wilson warehouse miles and miles from Yankee Stadium.
"We have the same [glove] company," Cervelli said. "That's what they sent me, so I've got to use it. That's my glove. I don't know, maybe later when I've got more years in the big leagues, they'll put my name on it. I don't really care."
Cervelli has played three innings at third base this season, including one on Monday, but he takes ground balls nightly during batting practice to stay sharp. That led to some confusion when the Mets played the Yankees earlier this season.
"I left my glove outside, and the clubbies thought it was David's glove, so they put it in his locker," Cervelli said. "He's a nice guy. He got confused and said, 'I'm so sorry.' I want him to sign my glove when the season's done. I'm going to send it to him."
