Pineda making strides on rehab assignment

NEW YORK -- Right-hander Michael Pineda's next Minor League rehabilitation start will come on Thursday for Class A Advanced Tampa in Dunedin, Fla.

Yankees general manager Brian Cashman said that the 24-year-old is expected to throw about 80 pitches in the outing against the Blue Jays' Florida State League affiliate, and Pineda's reports have been positive coming off right labrum surgery.

Cashman said that Pineda has been sitting around 92 mph with his fastball, topping out at 94-95 mph. It is possible that he would be available to make his Yankees debut in July.

"The reports have been really good," Cashman said. "He's had a very good rehab process without issues. I think, over time, you're going to get a chance to see more [velocity] if there's more there as he gets stretched out, but that's where he's at so far."

Teixeira could be headed to disabled list

NEW YORK -- Yankees general manager Brian Cashman said Monday that he is leaning toward placing first baseman Mark Teixeira on the 15-day disabled list, but a final decision has not yet been made.

Cashman said on a conference call that he has been told Teixeira will not be available to play for at least seven days after having a cortisone injection to treat inflammation in his right wrist.

"I'm leaning, personally, toward the disabled list there, just because as I've been informed, he took the shot and he'll be down because of the shot for a few days," Cashman said. "Then you've got to get him going slowly with tee work and building up to batting practice.

"He wouldn't be a player for us for seven days at the minimum, and that only takes you through batting practice. Given what he's going through, giving him the extra week is going to make a lot more sense."

Teixeira, 33, removed himself in the fourth inning of Saturday's game against the Angels in Anaheim, saying that he did not feel the proper "snap" in his wrist while batting. An MRI taken in New York revealed no new tear in his tendon sheath.

The injury has affected Teixeira most when batting from the left side; hitting coach Kevin Long revealed in Anaheim that Teixeira has been unable to perform his usual tee drills from that side of the plate because of the discomfort, a comment that took Cashman by surprise.

"It's alarming in the fact that K-Long would say that to the group of reporters, but he never said that prior," Cashman said. "This is a lot of times how things work out when things go bad. If K-Long felt that way, he should have been saying that from Day 1, but we never heard that from K-Long.

"Am I mad at Kevin Long because of that? No. But do I think that that commentary jibes with Kevin Long's comments internally in that clubhouse regarding this player prior to him going down? The answer absolutely is not."

Teixeira is batting .151 (8-for-53) with three home runs and 12 RBIs in 15 games for New York this season, and his struggles from the left side were no secret: he has just three hits in 35 at-bats against right-handed pitching.

Teixeira initially suffered a torn tendon sheath in March while preparing to play for Team USA in the World Baseball Classic. Cashman said that the Yankees were as conservative as possible with his recovery, but the 30 percent chance that he will need season-ending surgery has not changed.

"Like before the season started, when this injury hit, he'll either get through it or he'll have to have surgery," Cashman said. "The MRI showed no new tear, it's not a reinjury there. It's inflammation of the tendon.

"But is this something that's a recurring theme because of the previous injury that's going to prevent him from being all he can be? If that's the case, he'll have to have surgery."

Cashman added that if Teixeira will be a limited player from the left side of the plate all season, his preference would be that Teixeira have surgery rather than play part-time or abandon switch-hitting.

"I would think that if it's something that is going to prevent him from playing, that would make him a part-time player, I'd rather he just go get it fixed," Cashman said.

Lyle Overbay will return to regular duty at first base with Teixeira sidelined. Cashman said that he still believes it was the right decision to have Teixeira rehab his wrist injury rather than have surgery in the spring.

"Certainly the way this year is going so far, the odds haven't been in our favor in terms of injuries and how they respond," Cashman said. "At the end of the day, I have no regrets on that aspect.

"He wouldn't have played all year, and if he has the surgery, he won't play the rest of the year. If he had the surgery back then, we wouldn't have had him all year regardless. This still gives him a chance to fight through it."

Cashman not counting on Youkilis to return

NEW YORK -- Kevin Youkilis is on the 15-day disabled list for the second time this season with a back ailment, and Yankees general manager Brian Cashman said that the team cannot count on his return.

"Back issues usually don't get better," Cashman said on a conference call Monday. "They can, but they're very debilitating and hard to get a handle on. It's definitely a concern. As of right now, I'm not planning on him [returning] until they tell me I can plan on him."

The 34-year-old Youkilis was scheduled to see back specialist Dr. Robert Watkins on Monday after complaining of numbness in his right foot and calf, and Cashman said that the Yankees had not yet received results of that visit.

"I just know he's not the player that he can be, because of the back right now," Cashman said. "Are we going to be in a position to get that player back at some point throughout this season? It would be nice."

Youkilis is batting .219 (23-for-105) with two home runs and eight RBIs in 28 games for the Yankees this season, and he was 6-for-41 since returning from his first DL stint for a lumbar spine sprain.

Cashman said that Youkilis passed his physical with "flying colors" before inking a one-year, $12 million deal in January, and that he had been comforted by also knowing the White Sox -- with whom Youkilis ended the 2012 season -- offered the veteran a two-year contract.

Bomber bits

• Alex Rodriguez (left hip surgery) will advance to facing live pitching under simulated conditions on Tuesday at the Yankees' complex in Tampa, Fla. Rodriguez took three rounds of batting practice and ground balls with slow rollers on the field Monday.

• Derek Jeter (left ankle fracture) took 15 swings in a batting cage on Monday, as well as 20 ground balls on the dirt with movement to the side and throws to first base.

• Eduardo Nunez (oblique) hit off a tee, performed long toss and took ground balls on the dirt with throws on Monday. He could rejoin the big league club before the All-Star break.

• Curtis Granderson (fractured right hand) will have a pin taken out of his hand on Thursday before advancing to a week of grip and strength exercises.

• Francisco Cervelli (fractured right hand) did long toss and receiving drills on Monday. He is scheduled to begin swinging a bat under water in about a week and could rejoin the big league club in mid-July.
