Aaron Judge’s Calf Strain Is the Cost of a Rushed Return

The New York Yankees are placing captain Aaron Judge on the 10-day injured list Saturday with a right calf strain. An MRI in Phoenix on Thursday confirmed the injury, seven games after he came back from a fractured rib, and manager Aaron Boone would not give a grade or say whether Judge will play in October.

The club is placing Judge on the injured list after he left Wednesday’s 5-4, 13-inning loss at Minnesota in the sixth inning. Utilityman Max Schuemann is coming from Triple-A Scranton/Wilkes-Barre as the matching roster move.

The Yankees Are Parking Aaron Judge for a Calf Strain

Judge felt stiffness in his lower right leg in the first inning at Target Field and tried to stay in because, as he put it, these games count down the stretch. He came out before his sixth-inning at-bat so he would not cost the team in the field or on the bases. The Yankees treated him through Thursday’s off day, then the MRI showed a strain, and Boone spoke Friday in Phoenix before the club opened a series at Chase Field.

I don’t have a timeline on him. I’m not going to predict anything. We’ll just obviously treat it and see what transpires.

Aaron Boone, Yankees manager, Friday in Phoenix

Asked if Judge would be back for the playoffs, Boone said, “I don’t know.” He also declined to give the grade of the strain. Infielder-outfielder Schuemann was already traveling to meet the club for Saturday’s game. Judge did not speak Friday.

THE WEEK THE CALF GAVE OUT

1. Sept. 16: Leaves the Twins game in the sixth after feeling tightness in the first inning.
2. Sept. 17: MRI in Phoenix shows a right calf strain; the Yankees treat him on an off day.
3. Sept. 18: Club says it will make the 10-day move Saturday and will not project a return.
4. Sept. 19: Official placement, with Schuemann taking the roster spot.

If the stay is backdated to Thursday, Sept. 17, the earliest Judge can come off the list is Sept. 27, the regular-season finale against Baltimore. The American League Wild Card Series is set for Sept. 29, with the Yankees, as of Friday, lined up to host Boston. He will sit the Arizona series and a four-game set with the Tampa Bay Rays at Yankee Stadium from Sept. 22 to 24.

Seven Games Was Not a Real Ramp-Up

Judge last played before the rib stay on May 31 against the Athletics in West Sacramento, then returned Sept. 8 against the Colorado Rockies. That is a 99-day gap from June 1 through Sept. 7. He skipped a minor-league rehab assignment, and Boone said Friday he would not second-guess that choice because “these things happen with a rehab assignment or without one.”

The seven games he did play were not a full build. He did not play complete games his first two days back, and the club was off on Sept. 10 and Sept. 15. In those seven games he went 4-for-23 (.174) with one home run, still trying to find timing after the long layoff. On Wednesday he compared the tightness to the little things that show up in spring training while a player is ramping up, except it is September and a wild-card series is less than two weeks away.

THE COMPRESSED RETURN

• The rib month: He first felt the right rib on April 26, his 34th birthday, on a diving catch against Houston, and he also mentioned a crash into the wall May 3 against Baltimore.
• The last swing: He kept playing about a month, until the pain became too much after the May 31 game in Sacramento, and general manager Brian Cashman later said playing through it probably made the fracture worse.
• The 99 days: He missed the summer, then bypassed minor-league games and walked back into big-league pitching on Sept. 8.
• The seven games: Partial early outings, two off days, then tightness in the first inning on Sept. 16 that he tried to play off.
• The player’s own line: After the Twins game he said that once you start ramping up, things pop up, and he hoped it was one little thing.

He had already answered the rehab question before the MRI. People blow out calves and quads on rehab assignments, he told reporters, so he did not think a game in Double-A would have changed that. The point is not that a few innings in Somerset would have saved the muscle. The point is that three months of lost running load, then seven big-league games, is a spring-training stress in a playoff month.

A Rib Layoff Leaves the Lower Leg Undertrained

Judge is 6-foot-7 and 282 pounds, one of the largest everyday players in the sport, and the calf is the first tissue that takes the ground when that frame runs, brakes, or starts the swing. A rib fracture on the right side kept him from rotating and from taking a full swing for months. Running and lower-leg strength were not the injury, so they were easy to treat as background while the bone healed. They are not background when a 282-pound right fielder has to sprint, stop, and drive off the front leg again.

A 2022 study in Sports Medicine – Open interviewed 20 expert sports clinicians who treat calf muscle strains and described the muscle as the first point of loading in the chain. Recurrence, those clinicians said, often follows a return before the tissue can take sprint load, plyometric work, and repeated decelerations. That is the job description of a Yankees right fielder in September.

Judge’s own at-bats after Sept. 8 already showed a body still catching up. The average (.174) is the public stat. The hidden one is the running and braking he had not done at game speed since May. Cody Bellinger, who has been through his own leg rehab this year, said Judge wants to be out there every day and called the news frustrating after so much work to get back. “Hopefully it’s something small and quick,” Bellinger said.

How Long a Calf Strain Keeps Him Out

Boone’s silence on the grade is the medical story. A strain that is not graded in public is a strain the club does not want on a calendar. Bryan Hoch, the Yankees reporter for MLB, wrote after the briefing that even a Grade 1 needs 2-3 weeks to recover, and that the club was not revealing a timetable. A 2025 review of calf strains in athletes put published 2 to 12 weeks to return, with milder injuries often in a 2-to-6-week band and severe ones at 6 to 12 weeks.

CALF STRAIN RETURN WINDOWS

Count the days from the night the calf tightened. Sept. 16 to the wild-card opener on Sept. 29 is 13 days. Even the short Grade 1 window of 2 to 3 weeks lands on Sept. 30 through Oct. 7, after Boston would already have been in the Bronx. The 10-day list can make him eligible on Sept. 27. Eligibility is not the same as a calf that can sprint, stop, and drive a 282-pound swing against playoff pitching.

His Right Calf Already Cost a Month in 2020

This is not a new muscle for him. In the short 2020 season, after a stress fracture of the same first right rib that had lingered from a dive in 2019, Judge strained the right calf, went on the injured list with what Boone then called a very mild Grade 1, and missed 28 of 60 games. He had begged the club not to make the first IL move, saying he could have been back in a couple of days. He came off the list, felt the calf tighten again while running the bases, and went right back on it.

I tried to kind of play it off and see how long we could go, because these games are important down the stretch. But kind of talking it over, I thought it’d be the right move to come out, so I don’t cost the team on the field or cost the team on the basepaths.

Aaron Judge, after leaving the Twins game on Sept. 16

The 2020 lesson sits next to that quote. He still tried to play this one off in the first inning. The club still needed an MRI a day later to name the muscle. A mild calf that is rushed back has already shown, in his own history, that it can become a second stay in the same month. Parking him for 10 days is the move they would not let him talk them out of in 2020, and it is the move they are making now.

Giancarlo Stanton Has Already Paid This Bill

The same clubhouse has been living with calf tissue all year. Designated hitter Giancarlo Stanton, another oversized right-handed slugger, has been out since late April with a chain of calf strains: a right calf that landed him on the list April 28 (retroactive to April 25), a setback in that same calf in June, then a moderate strain in the left calf in August while he was running during rehab. The Yankees moved him to the 60-day list on Aug. 25. Boone said as recently as Sept. 13 that Stanton was still hitting and that nothing was imminent.

That is the quiet context for Judge’s MRI. Two of the largest hitters on the roster have now had their seasons bent by the same muscle group, and Stanton’s third strain came during the running work that is supposed to prove a player is ready. Center fielder Trent Grisham is already on the 10-day list with a Grade 2 right hamstring strain and is a maybe for October. Second baseman Jazz Chisholm Jr. went on the list Sept. 10 with a sprained right thumb. The Yankees have been building lineups without their captain for most of the summer. They will do it again through the Rays series.

On the season Judge, the reigning American League MVP and a three-time winner of that award, is batting.241/.360/.511 with 18 home runs and 41 RBIs in 66 games. The Yankees entered Friday’s play at 88-64, five games behind the Rays at 93-59, with a playoff spot already in hand. Bellinger said missing Judge hurts, called him the best hitter in the game, and said the talent in the room still has to find a way.

When Can Aaron Judge Return for the Playoffs?

The honest answer is the one Boone kept repeating. He does not know. The list creates a date, not a medical clearance. Sept. 27 is the first day the roster rules allow him back. Sept. 29 is the first day the bracket is scheduled to need him. Thirteen days after a calf strain is not a Grade 1 rehab, and it is not a 2-to-6-week mild-to-moderate rehab. It is a date on a pocket schedule.

WHAT WE KNOW

• The diagnosis: MRI-confirmed right calf strain after tightness on Sept. 16, with the 10-day IL dated for Saturday.
• The floor: Earliest activation is Sept. 27 at Baltimore if the stay is backdated to Sept. 17.
• The build that failed: 99 days off after the rib, no rehab games, seven big-league games, then the calf.

WHAT IS UNCONFIRMED

• The grade: Boone would not say whether this is Grade 1 or worse.
• October: No club projection for the wild-card round or anything after it.
• How he trains: No public plan yet for running progressions, hitting, or whether he will be limited to DH when he does return.

Shutting him down for the postseason is the loud take, because a calf that still cannot take a full sprint is a liability against Boston. The quieter reading of the same facts is that the 10-day list is the first load management that matches the muscle. Boone still will not grade the strain. The wild-card round is dated Sept. 29, 13 days after the night the calf tightened in Minneapolis.
