Andy Pettitte (trapezius) threw a successful bullpen session Saturday. Pettitte will next throw in an extended spring training game, though the Yankees will wait to see how he feels Sunday before deciding on when that will happen. If he can avoid a setback, Pettitte could be activated when first eligible on June 1.

Andy Pettitte (trapezius) played catch Thursday and Friday and is scheduled to throw a bullpen session Saturday. Pettitte was placed on the disabled list last week with a strained trapezius muscle, but he's currently throwing without any discomfort. The veteran left-hander expects to throw a simulated game rather than go out on a minor league rehab assignment. Either way, he should return around when he's first eligible on June 1.

Andy Pettitte (trapezius) will play catch either Thursday or Friday. It will be the first time he's thrown since landing on the DL last week with a strained trapezius muscle. "Then we'll do some long toss, a bullpen and hopefully work it up to a simulated game," Yankees manager Joe Girardi said. Pettitte is expected back on June 1, the first day he's eligible, or shortly after that.

Yankees placed LHP Andy Pettitte on the 15-day disabled list with a strained trapezius muscle. Pettitte suffered the injury during Thursday's start against the Mariners. It's believed to be minor, but the Yankees don't want to take any chances with the 40-year-old southpaw. Vidal Nuno is slated to replace him on the active roster and will likely get a start or two.

Yankees manager Joe Girardi said Andy Pettitte (shoulder) will likely be placed on the disabled list if he needs to miss a start. The good news is that there's a chance he might not have to miss a turn after exiting Thursday's outing with a tight left trapezius muscle. Pettitte obviously dodged a serious injury bullet, but the Yanks could still play it cautiously and put him on the shelf for a couple weeks.

The Yankees indicated after Thursday's game that they're not too concerned about Andy Pettitte's tight left trapezius muscle. It's good to hear, though it remains unclear whether he'll be able to make his next start. It appears that the Yankees will not sent Pettitte for an MRI. More details about his status should be available on Friday.

Andy Pettitte left Thursday's start against the Mariners with a tight left trapezius muscle. The trapezius is located in the upper back/neck area. It's not clear at this point how severe the ailment is, but it seems likely that Pettitte will have to miss at least one start. Ivan Nova (triceps, side) would be an option to replace him in the rotation.

Andy Pettitte left Thursday's start against the Mariners in the fifth inning with an apparent injury. Pettitte whiffed the first two batters of the fifth before Yankees manager Joe Girardi came to get the left-hander. He dealt with back spasms last month, but it's unclear if that's the issue this time. The club will provide an update on his status soon.

Andy Pettitte delivered seven strong innings in Saturday's victory over the Royals, surrendering just two runs. Pettitte fanned seven on the night while issuing only one free pass and allowing only five total hits. He yielded a run in the third inning on an RBI groundout off the bat of Lorenzo Cain, then Billy Butler tagged him for a solo shot in the fourth, but that was the extent of the damage. It was a nice bounceback effort from the veteran lefty, who was hit hard in his previous two starts. He'll carry a 4-2 record, 3.83 ERA and 1.28 WHIP into Thursday's home matchup against the Mariners.

Andy Pettitte struggled for the second straight start Sunday, allowing four runs -- three earned -- on four hits and four walks over five frames in a loss to the Athletics. Pettitte struck out just two, which is the same number of home runs he allowed. He needed 100 pitches to get through the five frames, and his four free passes represented more than half of his second total coming into the game. Pettitte's ERA has gone from 2.22 to 4.06 after a pair of clunkers. He'll try to rebound next weekend in Kansas City.
