May 7: INF Oswald Peraza, RHP Nick Burdi on rehab assignments; OF Taylor Trammell outrighted to Triple-A Scranton/Wilkes-Barre
Peraza began his rehab assignment with Single-A Tampa on Tuesday, while Burdi had his rehab assignment transferred to Triple-A Scranton/Wilkes-Barre after his first rehab game at Double-A Somerset was rained out on Sunday.

Burdi is only expected to need one to two rehab outings before he's ready to return to the Yankees' bullpen. Peraza is further away from a return to the big leagues.

Manager Aaron Boone said the infielder will need to go through a multi-week ramp-up. That will start in Tampa with Peraza playing four or five innings for a few games, with off-days mixed in, before potentially being transferred to Double-A Somerset or Scranton/Wilkes-Barre, where he would build up to playing full games and back-to-back days.

The 26-year-old Trammell has played in five games for the Yankees this season, mainly as a pinch-runner and defensive replacement, and has a hit and a walk in two plate appearances.

10-DAY/15-DAY INJURED LIST

INF DJ LeMahieu (non-displaced fracture of right foot)
Expected return: Possibly May
LeMahieu has resumed baseball activities. He started hitting in the batting cage on May 4 and started taking ground balls in the infield on May 7. He was previously throwing and doing dynamic warmups moving around the field.

There is not yet a set timeframe for LeMahieu's return, but he will travel with the Yankees on their upcoming road trip to play the Rays from May 10-12, so he can take live at-bats and do infield work at the team's complex in Tampa.

"DJ's had a good few days," manager Aaron Boone said. "I know he's feeling really well. ... We'll be kind of ramping him up, baseball activities all week."

After that, LeMahieu could potentially start a new Minor League rehab assignment, Boone said.

"With the time he's missed now, it's about, when we get to the point of getting back in games, how many games does he need?" Boone said on May 5. "So we'll see."

LeMahieu has yet to play in a big league game this season after sustaining a non-displaced fracture of his right foot on a March 16 foul ball. He first began a rehab assignment on April 23, but that was shut down after only one inning when LeMahieu experienced soreness in his foot.

Boone said on May 1 that no re-imaging will be necessary for LeMahieu because "it’s a tolerance thing at this point." (Last updated: May 7)

RHP Nick Burdi (right hip inflammation)
Expected return: May
Burdi was transferred to Triple-A Scranton/Wilkes-Barre to continue his rehab assignment on May 7 and is scheduled to pitch one inning in his first game there. The right-hander started his rehab assignment on May 5 with Double-A Somerset, but the Patriots were rained out, so Burdi threw an inning of live batting practice against the Yankees' Double-A hitters instead of pitching in the game.

Burdi is only expected to need one or two rehab outings before returning to the Yankees' bullpen. Manager Aaron Boone said Burdi is "champing at the bit" to return to game action.

Burdi received an injection on April 22 after feeling discomfort near the end of an April 16 appearance at Toronto. Boone said that because of Burdi's lengthy injury history, club medical personnel were wary of the hurler overcompensating in his delivery, which could lead to an arm issue. (Last updated: May 7)

INF Oswald Peraza (right sub-scapular strain)
Expected return: Possibly late May
Peraza began a Minor League rehab assignment with Single-A Tampa on May 7. He is still expected to be several weeks away from being ready to play in Major League games.

Manager Aaron Boone said Peraza will need to build up before he would be an option to rejoin the club. He'll start by playing four to five innings for a few games in Tampa, with days off in between, before the Yankees potentially move him to Double-A Somerset or Triple-A Scranton/Wilkes-Barre.

"He's kind of got to go through a full Spring Training of games now. So he'll have a pretty long runway," Boone said on May 7.

Peraza had been hitting and going through a throwing program at the Yankees’ complex in Tampa. He began throwing regularly during the first week of April following his injury, which began as tightness in his shoulder on Feb. 25. Peraza briefly returned to Spring Training action in early March, but the issue persisted when he threw across the diamond. (Last updated: May 7)

RHP Tommy Kahnle (right shoulder inflammation)
Expected return: Possibly May
Kahnle is nearing a rehab assignment. He is expected to need only one or two more live batting practice sessions before pitching in Minor League games, manager Aaron Boone said on May 3.

The right-hander will throw the first of those live sessions on May 4. After that, the Yankees will determine whether he is ready to proceed directly to rehab outings or needs one more live BP first.

Kahnle tossed 15 pitches over one simulated inning on April 27 in Tampa, Fla., according to Boone, which represented his first time doing so since Spring Training. Boone said that he has exchanged text messages with Kahnle, who is said to be "pretty excited about where he’s at now physically. He feels like it’s getting to where it needs to be."

Kahnle was slow-played during the spring after right shoulder inflammation ended his 2023 season and delayed his winter throwing program until Dec. 12. Though Kahnle was aiming to rejoin the Yankees when eligible on April 9, he experienced soreness after a throwing session on or around April 1, prompting the club to delay him further.

60-DAY INJURED LIST

RHP Gerrit Cole (right elbow discomfort)
Expected return: Possibly June
Cole resumed throwing off a mound on May 4 at Yankee Stadium, throwing 15 fastballs in a significant step in his recovery from right elbow discomfort. He threw another bullpen session on May 7.

"We've still got a ways to go on it. But exciting that he's getting back out there again," manager Aaron Boone said. "I think he's going with us to Tampa and will hopefully get back on the mound this weekend, and maybe over to our complex to do some things on the pitching side. I continue to be encouraged with how he's doing."

The reigning American League Cy Young Award winner is expected to need at least four to six weeks to ramp up once he begins pitching, and the Yankees do not have a specific timetable for their ace yet.

“I think everyone in this room understands Gerrit, who he is, how much he loves what he does, and obviously, how good he is at it,” Boone said on May 4. “So it’s just the process of getting back, another step along the way to getting him back. Glad we were able to get to this point today. Onward and upward.”

Cole is expected to travel with the Yankees to Tampa for the team's series against the Rays from May 10-12, where he can do some rehab work at the Yankees' complex there.

The right-hander underwent an MRI on March 11 after relaying difficulty bouncing back between his spring outings, likening his level of fatigue to what he usually would feel after throwing 100 pitches during the regular season. Cole had more testing performed on March 12, then visited Dr. Neal ElAttrache in Los Angeles on March 14. ElAttrache confirmed that there was no damage to Cole’s ulnar collateral ligament.

OF Jasson Domínguez (right UCL tear)
Expected return: June or July
Domínguez is expected to be ready to start playing in Minor League rehab games by mid-May, manager Aaron Boone said on May 7.

"I think he's inside of two weeks," Boone said. "Probably the first two weeks will be all DH, but yes, he's getting close to starting games."

Domínguez has been taking live batting practice and doing defensive work, and was throwing from 135 feet as of the end of April.

The 21-year-old was diagnosed with a partial tear of the ulnar collateral ligament in his right elbow on Sept. 10, 2023. He underwent Tommy John surgery 10 days later, which included the addition of internal bracing. Dr. Keith Meister performed the procedure in Arlington. He resumed hitting right-handed on Feb. 26, then began taking swings from both sides of the plate in mid-March. (Last updated: May 7)

RHP Lou Trivino (recovery from Tommy John surgery)
Expected return: Summer 2024
Trivino is about two weeks away from beginning live batting practice sessions, manager Aaron Boone said on April 21. Boone remarked that Trivino has been “doing really well,” noting that his bullpen sessions during Spring Training were encouraging. Trivino is recovering from Tommy John surgery performed on May 3, 2023. (Last updated: April 21)

RHP Scott Effross (Tommy John surgery, back surgery)
Expected return: Summer 2024
Effross underwent Tommy John surgery in October 2022 and began a throwing program on March 6, 2023. According to manager Aaron Boone, Effross began experiencing back discomfort in the fall, which prompted a microdiscectomy of his L-4 and L-5 vertebrae in December. Boone said on April 21 that Effross has been “doing pretty well,” though his recovery has been marked by a few minor hiccups. (Last updated: April 21)

RHP Jonathan Loáisiga (right UCL tear)
Expected return: 2025
Loáisiga said on April 6 that he has a torn UCL and needs season-ending surgery. Dr. Keith Meister will perform the procedure, which Loáisiga said has an estimated recovery time of 10 to 12 months. Loáisiga was placed on the 60-day injured list on April 5, retroactive to April 4. (Last updated: April 6)
