Red Sox Video
Since signing a five-year, $90-million contract in December 2022, Masataka Yoshida has mostly lived up to his profile, but failed to deliver on the great ceiling that his seven-year run in the NPB with the Orix Buffaloes portended: a .327/.421/.539 slash line with 133 home runs. Over his first two seasons with the Red Sox, the former outfielder has played in 248 of a possible 324 games, accrued 2.8 WAR, posted an OPS of .775 and OPS+ of 111, and produced 82 extra-base hits. That’s hardly a porous performance, but for a guy making $18 million per year — tied for the third-highest figure on the team last year, behind only Rafael Devers and Trevor Story — it pales in comparison to what the team needs.
Of course, Yoshida was dealing with multiple injury issues this past year, including a left thumb strain that sidelined him for nearly six weeks during the first half. Over the past month, fans have also become privy to a previously undisclosed shoulder injury that required Yoshida to get an MRI in late-September. On Wednesday, we found out the severity of that injury, as the team announced that Yoshida had shoulder surgery nearly two weeks ago.
Naturally, shoulder injuries are a big deal for hitters, and the timeline for previous labrum surgeries offers a wide range of possible outcomes for Yoshida’s recovery. Baseball Prospectus’s Recovery Dashboard, lists six position players who underwent shoulder labrum surgery since 2016, as well as how long it took for them to return to game action in the major leagues.
| Year | Player | Days |
| 2016 | Greg Bird | 183 |
| 2019 | Miguel Andujar | 140 |
| 2023 | Brendan Rodgers | 128 |
| 2023 | Garrett Mitchell | 162 |
| 2023 | Logan O'Hoppe | 119 |
| 2023 | Vinnie Pasquantino | 114 |
| Average | 141 | |
| Median | 134 |
The average player rehabbed for roughly 4.5 months, so assuming an average recovery, that would put Yoshida’s return at February 21, 2025. That’s exactly one week after pitchers and catchers report on February 14, and two days after the first full-squad workouts begin on February 19. Now, there’s a wide range of outcomes in that table, and the best-case scenario appears to be a sub-four-month rehab period, while the longest recovery window was more than six months. That means Yoshida could be ready to roll before Spring Training starts, or he could be out until late April. Most importantly, this is a small data set of players with similar surgeries. The severity of Yoshida’s injury is unknown to the public, and his exact timeline could differ for any number of reasons.
Thus, fans should expect the Red Sox to act in accordance with the information they have. If they know Yoshida will be out for longer, a free agent move for another big bat (Alex Bregman? Teoscar Hernández?) would be even more advisable than it already is, and could also put Boston squarely in the trade market for a big bopper to slot in alongside Devers and Tristan Casas in the heart of the order. Alternatively, if there's reason for optimism about Yoshida’s health prior to Spring Training, the BoSox could use that as an excuse to not open up the purse strings this Winter.
This news also further wrecks Yoshida’s trade value, which was already a huge question mark last offseason, when the then-primary left fielder was deemed to have an “untradeable contract”. Yoshida simply won't command much in a trade as a designated hitter without a ton of over-the-fence power. However, improved plate discipline (his strikeout and walk rates improved from 2023 to 2024), and an increased fly ball rate (19.4% in 2023, 24.4% in 2024) could have at least given the Red Sox some added leverage in discussions. There's an argument to be made that Yoshida managed an above-average season at the plate despite playing hurt all year, and that he could improve once he's fully healthy. Still, no team will be champing at the bit to acquire $54 million in remaining salary for a player who went under the knife just two weeks ago.
For now, Yoshida will remain in Boston while rehabbing his injury, and the Red Sox will wade into one of the most important offseasons in recent memory with one of their highest-paid players as a gigantic unknown.
