Jarren Duran's Terrible Season Shouldn't Become A Common Occurrence, but the Red Sox Might Not See It That Way

[Yirsandy Rodríguez]

It is difficult to forget the recent image Jarren Duran left behind, being completely shut down by the New York Yankees pitchers for the second consecutive year in the Wild Card Series. His presence in the last two postseasons with the Boston Red Sox has been disappointing, finishing 1-for-14 with five strikeouts.

Look, I like Duran, and we all know that, given his tools, he can be a very useful player, but the problem here is that since his breakout season in 2024, he has declined every year. Just look at some of his percentile rankings over the past three years.

He is still an elite runner and a fielder who could once again outperform the average player, but in batting value, he has fallen from the 96th percentile to the 1st. Yes, Duran just finished his second 20-20 season in the last three years. But in 2026, he finished with the worst offensive line of his entire career, batting .207/.266/.361, with just a 69 wRC+ and .627 OPS. His fWAR of 0.5 is so much worse than 2024 that you might as well be talking about two different players.

The decline in his impact on the game in terms of consistency was too great. His strikeout rate fell to the worst mark of his career in qualified seasons, at 27.1%, which was combined with his worst regression in BABIP (.252), falling below his .300 standard for the first time.

The problem with his slugging comes from the fact that Duran has not been able to produce the same amount of extra-base hits, especially doubles and triples, as in his previous two campaigns, like when he led the league with 48 doubles and 14 triples in 2024. Last year, he again surpassed 40 doubles and led the league once more with 13 triples. This year, he hit just 15 doubles and five triples, and it is clear that the problem was not just his ability to put the ball in play. Duran maintained elite bat speed, continued to be the same hitter with high chase and whiff rates, and struggled against left-handed pitchers. None of that is new.

His ability to generate hard-hit balls did not completely collapse either, finishing in the 60th percentile in Barrel%. So, what made a notable difference was the results of his balls in play. Duran recorded the worst xBA (.273) and xSLG (.388) marks of his career, and he was unable to compensate for part of the decline in his on-base percentage because he finished with the second-worst walk rate of his career (6.7).

At this point, breaking pitches and off-speed pitches were responsible for most of Duran’s regression. His whiff rate exceeded 38.0% against both pitch groups, but when he hit them, the result was just as worse, finishing with just a .199 xBA against breaking pitches and .211 against changeups. In contrast, Duran was lethal against fastballs, producing 14 of his 20 home runs and a .479 xSLG.

As you can see in this graph, Duran was pretty good at crushing pitches down the middle and in the upper third of the strike zone and, in general, when he managed to pull any pitch, his production rose to a 159 wRC+. However, his reduced hot zone against the mix of breaking balls and changeups can be seen in the lower and outside part of the zone, far from his best contact point.

The power profile Duran offers has always been interesting, but his great ability to impact the game comes with his speed. So, a runner with his skills definitely needs to be more consistent at getting on base, especially in a Red Sox lineup that does not rely on power.

What I enjoy most about the conversation surrounding Duran’s 20-20 season, or any other player’s, is not exactly the numbers. Hitting home runs and stealing bases at that level is not easy at all, but doing it in situations that truly add greater value to the probability of winning also makes a difference in the game.

In Duran’s case, his 20-20 was really more like a solid 15-15, as he managed to produce 16 home runs that positively impacted the scoreboard for the Red Sox. He hit seven home runs with the game tied, four when the team had a lead of two runs or fewer, and the same number when they were trailing by three runs or fewer. Something similar happened with his stolen bases, recording 15 in situations when the team was tied, or trailing or leading by a margin of three runs.

If he can right the ship in any of these regards—more extra-base hits, better production against breaking balls and off-speed pitches, or performance in clutch moments—Duran can still be a valuable piece of the Red Sox. But when everything comes together like it did in 2026, it's a lot easier to find the flaws in his game.
