Jake Bennett’s Rookie Season With Red Sox Was Even Better Than the Numbers Suggest

While the end of the 2026 season didn’t go how the Boston Red Sox wanted, that doesn’t change how good their pitching staff was throughout the year. They allowed the second-fewest runs in all of baseball, giving up just 611 over the course of the season. That’s an especially impressive number when you consider the fact that Garrett Crochet missed most of the year with shoulder issues. The Red Sox had plenty of different pitchers step up when they needed them, and one of the biggest contributors was rookie left-hander Jake Bennett.

Bennett was acquired by Boston from the Washington Nationals this past winter in exchange for fellow pitching prospect Luis Perales. At the time, it was an interesting swap of two talented prospects, but so far, the Red Sox are looking like the clear winners. After posting a ridiculous 1.60 ERA across nine starts with Triple-A Worcester to begin the season, Bennett earned his first opportunity in the majors. He didn’t look like a rookie once he got there, either; the southpaw quickly established himself as a reliable part of the rotation and wound up putting together a very impressive first season in the big leagues.

He finished the year with a 3.65 ERA and a 1.10 WHIP across 113.1 innings, along with 91 strikeouts and just 21 walks. Those are some pretty sharp numbers for a rookie pitcher, especially one who was making the jump from Triple-A to the majors for the first time. And the truth is, Bennett actually pitched even better than those numbers would indicate.

Both his expected ERA (xERA) and FIP came in lower than his 3.65 ERA, suggesting some positive regression might be coming his way in the future. Bennett also didn’t put up the kind of strikeout numbers that immediately jump off the page, but that’s not really what his game is about. Instead, he found other ways to make hitters uncomfortable. His chase rate was in the 98th percentile among all qualified pitchers, with more than 37% of the pitches he threw outside the strike zone generating swings. That's the kind of blue-chip skill that can carry a profile at the highest level.

Bennett’s arsenal isn’t necessarily designed to overpower hitters. It’s built around keeping them off balance, changing speeds and generating weak contact. He leaned heavily on his changeup and sinker as his primary secondary pitches off his four-seam fastball, and all three pitches have similar horizontal movement. They all tail in on left-handed hitters and away from right-handed hitters, but they do so with different speeds and vertical profiles. That makes it extremely difficult for hitters to sit on one pitch, especially when Bennett threw all three of them at least 24% of the time. He also has a sweeper with a lot of bite, giving him another pitch capable of generating swings and misses below the strike zone.

But there’s another important reason he was able to generate so many chases: how much he works within the zone. Bennett’s 4.6% walk rate ranked in the 99th percentile among all pitchers. It’s one of the biggest reasons why his approach worked so well. It’s a lot easier to get hitters to chase pitches outside the zone when you’ve already established that you’re capable of throwing strikes consistently. He didn’t give hitters many opportunities to simply wait him out. He attacked the zone, avoided free passes, and then used his secondaries to get hitters to expand once he got ahead. It's all a rather mature approach for someone who spent the entire season as a 25-year-old.

On top of limiting the walks, Bennett also did a pretty good job of limiting hard contact. He finished the season with above-league-average marks in both hard-hit rate and average exit velocity, while also doing a good job of keeping the ball on the ground. That’s another promising sign for a pitcher whose game isn’t built around simply blowing hitters away.

The foundation of what made him so successful throughout his minor-league career translated extremely well to the major leagues. His command, pitch sequencing, ability to change speeds, and knack for getting hitters to chase all carried over almost immediately. Of course, there are still things Bennett will need to prove as he gets more experience. Major-league hitters will have more information on him heading into 2027, and they’ll have a better idea of what to expect. He'll need to make the necessary adjustments and show he can keep delivering the same kind of results. But this was only his first taste of the big leagues, and there’s already a lot to like.

The Red Sox appear to have found a keeper. Despite the sour ending to the season, this is the kind of development that can make the organization a true championship contender in the future.
