NEW YORK — The soleus muscle is small enough that most people barely know it exists—until it makes itself felt.
Located beneath the larger calf muscle at the back of the lower leg, it is engaged with every push-off and weight transfer, including the rotation and follow-through of a swing that requires a hitter to drive through his back foot and finish upright.
For a hitter such as Aaron Judge, the muscle is activated on nearly every swing. It was involved in the 13 strikeouts he recorded during his abbreviated return from a broken rib. Now, apparently, it is the reason the Yankees are entering the most consequential week of their regular season without their captain.
New York placed Judge on the 10-day injured list Saturday with a right calf strain in the soleus, retroactive to Thursday. He will not be eligible to return until September 27, the final day of the regular season. That date is not a plan. It is a calendar technicality.
Judge said he felt tightness in his lower right leg during the first inning of Wednesday’s game in Phoenix. An MRI confirmed the strain. When manager Aaron Boone spoke Saturday, he offered no timeline for his return, and the decision not to put a number on it was more telling than a projection would have been.
“We just don’t know right now,” Boone said. “He’ll continue to be evaluated.”
What the Yankees know is this: they host the Tampa Bay Rays starting September 22 in a four-game series that represents their best remaining chance to close a five-game gap in the AL East. At 88-64, five games behind Tampa Bay at 93-59, New York needs near-perfect results from that series just to put pressure on the division leader. And they will do it without the man who has, by most accounts, been the difference between the two teams’ records.

The injury has also pulled the lens back to a decision made three weeks ago: Judge chose to return from a 99-day absence for a stress fracture in his right rib without completing a minor-league rehabilitation assignment. Boone backed that call. The Yankees put him back in the lineup on September 7 and watched him go 4-for-23, with 13 strikeouts, across seven games before the calf gave way.
“Not really,” Boone said Saturday, when asked whether he second-guessed skipping the rehab. He paused before answering.
Whether a rehab assignment would have revealed what the soleus was dealing with or forced more careful conditioning before the calf reached its current state is a question the Yankees cannot answer. What they do know is that Judge returned diminished, played through that state, and is now on the injured list again with the postseason ten days away.
Judge himself was direct. “I’d like to be back by the postseason,” he told reporters. “That’s definitely the plan.” The plan has no date attached.
Max Schuemann, a 26-year-old utility infielder with a career .234 average, was recalled from Triple-A Scranton/Wilkes-Barre to fill the roster spot. He is a capable defender and a useful piece. He is not what the Yankees are missing.
The Wild Card Series begins September 29. New York is the top AL wild-card seed, 5.5 games ahead of the Boston Red Sox, meaning their postseason berth is secure. What is not secure is the seeding, the matchup, or whether their captain plays in October at all. As CBS Sports reported, the earliest a full return can be expected is September 27, and a player recovering from a soleus strain who has also spent most of the season navigating rib and calf injuries is not the same as a player who has been healthy.
As Yahoo Sports noted, the timeline makes Judge’s playoff participation more uncertainty than assumption. He is eligible for the Wild Card roster if activated in time, but the calculus changes if the soleus does not respond to treatment inside the 10-day window.
The Rays series beginning Tuesday is the Yankees’ most concrete test of whether any of it matters. Tampa Bay holds the head-to-head tiebreaker, meaning a one-game New York advantage in the standings at the end of that four-game set would still leave the division in the Rays’ hands unless New York sweeps. That is the mathematical reality Judge is missing.
The broader playoff picture only intensifies the stakes. The Atlanta Braves clinched a postseason berth Friday, locking in the NL East while the AL East remains unresolved. In the NL West, Shohei Ohtani is expected back from his own IL stint as early as Wednesday. The Dodgers are managing their captain’s return with precision and a clear target date. The Yankees are managing the absence of theirs with a shrug and a hope.
Nobody in the Bronx will say when Aaron Judge comes back. They are hoping he does before it stops mattering.
