The Crimson Sox have had fairly the auspicious previous couple of weeks. Their 16-6 file since June 12 is one of the best in baseball, and so they’ve elevated their playoff odds to a season-high 48.0%, a wonderful efficiency for a crew that entered the 12 months with a sub-.500 projection. In a good AL Wild Card race, they’ve wanted each single certainly one of these latest victories, as Dan Szymborski just lately discovered that Boston’s playoff hopes are extra delicate to small modifications within the standings than these of another crew. Because the commerce deadline approaches, the Crimson Sox could discover themselves within the operating for large names. A lot of their present success, although, is due to main enhancements from gamers presently on the roster, corresponding to pitchers Tanner Houck and Kutter Crawford and catcher Connor Wong, whom Jay Jaffe wrote about yesterday. And no Crimson Sox participant has leveled up his sport greater than the present crew chief in plate appearances, runs scored, and WAR: Jarren Duran.
Duran’s breakout has come throughout his first season of full-time play; after cups of espresso in 2021 and ’22, he served because the sturdy aspect of a platoon final season, amassing a 120 wRC+ throughout 362 plate appearances. However there have been some indicators of future regression, as he outperformed his xwOBA by 35 factors and relied on a .381 BABIP to slash .295/.346/.482. And whereas these uncooked numbers from 2023 have really declined this season, to .275/.337/.473, Duran has put up an almost an identical 121 wRC+. Most encouragingly, he has a lot stronger peripherals backing up his slash line this 12 months, indicating that his present manufacturing is sustainable.
The most important change we’ve seen from Duran in 2024 is in his method on the plate. Beforehand, it appeared as if his purpose was to swing at something close to the strike zone and put the ball in play; he supplied on the first pitch almost 40% of the time. And whereas this technique labored for him as a result of he made loads of contact, regularly on a line, his success trusted well-placed balls in play and didn’t benefit from his energy. As a substitute, it usually felt like he sacrificed harm for contact, an pointless tradeoff given his stable bat-to-ball abilities, particularly on pitches within the strike zone. His energy numbers final 12 months – a twentieth percentile barrel price and thirty fifth percentile xSLG – had been removed from what he was able to.
Though Duran doesn’t seem like probably the most bodily imposing participant on the sphere, he has wonderful uncooked energy, with most exit velocities over 112.5 mph in every of the previous two seasons. He’s particularly deadly in opposition to pitches down and in, the place his bat velocity, exit velocity, and total manufacturing are all elite. Comparatively, he’s generated damaging run values in opposition to pitches on the outer third or prime of the zone, as his comparatively lengthy swing isn’t in a position to cowl the wanted distance in time. Understanding this, Duran has turn out to be extra selective. He’s lower his first-pitch swing price almost in half, watching such choices go by at almost Mike Trout ranges. He’s dropped his swing price on strikes in his chilly zones by 9 factors, along with a discount in chase price. The outcomes of those changes has been staggering, and Duran has regarded like a model new hitter this 12 months. Even with out a rise in uncooked energy, Duran’s give attention to swinging solely at one of the best pitches have vaulted his barrel price above the league common, alongside together with his xSLG and xwOBA. Moreover, his taking extra referred to as strikes has aided extra than simply his energy numbers: His strikeout and stroll charges have really improved together with his new method.
Remarkably, Duran legged out 34 doubles final 12 months, 10 extra two-baggers than he’s hit throughout 50 extra journeys to the plate this season. As we all know, as many younger gamers acquire extra expertise, they discover ways to flip these two-base hits into dwelling runs — or as Kiri Oler dubbed this improvement, “summiting Doubles to Dingers Mountain” — so it’s not all that shocking that Duran is hitting fewer doubles as he’s added energy. Besides, properly, he’s launching dwelling runs at almost the identical tempo as he did final 12 months, in 2.4% of his plate appearances this season, up barely from 2.2%. As a substitute, he’s managed to one-up his energy manufacturing in a far much less frequent method: He’s hitting far more triples. He’s nonetheless racking up loads of doubles (24, tied for the fifth most in baseball), however he leads the majors with 10 triples, eight greater than he hit final season. Altogether, he ranks fifth within the majors with 44 extra-base hits. He’s taking full benefit of the size of his dwelling stadium, as Fenway’s deep right-center discipline hole and the Inexperienced Monster in left make it probably the most doubles-friendly ballpark within the majors, particularly for left-handed hitters, and the fifth-most triples-friendly park. This season, Duran has 18 doubles in simply 133 balls in play at dwelling. Extra particularly, Duran’s capability to smack balls off the Monster is completely unparalleled. I checked out spray charts of different prolific Crimson Sox hitters in latest reminiscence – Rafael Devers, Xander Bogaerts, Mookie Betts – and none took benefit of their ballpark’s defining characteristic anyplace near as regularly as Duran has in 2024.
Lots of Duran’s 34 mixed doubles and triples this 12 months have resulted from his velocity on the basepaths, combating to take the additional bag at each alternative. He’s all the time possessed plus-plus velocity, and utilizing Statcast’s new baserunning worth leaderboard, we will see the run worth of each single he’s stretched right into a hustle double or base taken on a teammate’s hit. Duran ranks third within the league in such runs generated due to his aggression, and whereas a handful of speedsters have produced damaging worth from being overly cautious, Duran’s fearlessness has paid off. Aggressive baserunning has been an necessary a part of Boston’s total offensive enhancements this 12 months. The Crimson Sox have climbed to seventh in additional base taken price in comparison with twenty fifth a 12 months in the past. Statcast views them because the fourth-best baserunning crew in baseball. If you mix this with Duran’s 21 steals on 24 makes an attempt, the top consequence is without doubt one of the most precious runners within the league; moreover Duran, solely Corbin Carroll and Elly De La Cruz are on tempo to accrue 1 WAR from baserunning alone.
Whereas Duran has solidified his method on the plate and maintained his excellence on the basepaths, the world the place he’s seen probably the most dramatic enchancment this 12 months is together with his glove. Regardless of his ninety fifth percentile dash velocity, Duran’s earlier efficiency within the outfield, particularly in heart, left a lot to be desired; he totaled -5 FRV from 2021-23. Most of his poor performs occurred when he needed to cowl lengthy distances on environment friendly routes; it was so unhealthy that he made an look in a bit I wrote final 12 months because of his terrible route operating. In that piece, I discovered there was a damaging correlation between route effectivity and total OAA, as an outfielder’s preliminary response and burst velocity proved to be extra necessary elements. Duran has been a key instance of this: His routes are nonetheless tough, however the remainder of his defensive sport has improved tremendously. His +5 FRV ranks within the 89th percentile (although second to Ceddanne Rafaela in his personal outfield), whereas solely Daulton Varsho has extra DRS than Duran’s 12 amongst outfielders.

Duran’s reactions and first steps have improved to the purpose the place his routes haven’t impacted his capability to get to balls. Final 12 months, he didn’t make each of the difficult-but-possible performs that concerned protecting over 100 toes of floor to make the catch; this 12 months he’s an ideal 4-for-4. Nevertheless, the performs which have turned his defensive metrics from under common to wonderful aren’t the long-distance runs however the line drives, the place instincts and preliminary reactions are all the things. In 2024, Duran has had 11 play alternatives on balls between 30 and 50 toes away from him with fewer than 4 seconds to make the catch. He’s transformed 10 of them, contributing to half of his whole OAA. Whereas he was equally profitable at catching these arduous liners in earlier seasons, he had just a few such play alternatives. Duran isn’t doing something completely different together with his positioning this 12 months, so it stays to be seen whether or not he’ll proceed to get so many catch alternatives on these arduous liners. Regardless, it’s protected to say that he’s made the many of the fielding possibilities he’s been given.
Nearing the All-Star break, the Crimson Sox have as near coin-flip playoff odds as another membership, and the excessive stakes they’ve performed below mixed with their meteoric efficiency over the previous few weeks have made them one of the crucial thrilling groups in baseball to observe. And in the course of it’s the homegrown All-Star Duran, whose enhancements have manifested in each single side of his sport.
