Is Jhoan Duran Getting Even Nastier?

After I wrote about Red Sox outfielder Jarren Duran last month, consider this the next installment of my highly unrelated, only-for-the-joke “Duran Duran” series; today we take an entirely separate look at 25-year-old Twins closer and velocity king Jhoan Duran. This Duran was one of baseball’s best relievers as a rookie in 2022; this year, he returned to the Twins’ bullpen with a lot less to prove after his impressive rookie campaign. Nevertheless, he has made some significant tweaks to his already devastating arsenal, and he’s bringing more heat in his sophomore season than ever before.
Duran arrived on the scene in Minnesota last year at a rather uncertain time in his prospect journey. After registering on our Top 100 prospect lists as a high-velocity starter in 2020 and 2021, a forearm strain (and a global pandemic) limited the right-hander to all of five appearances across the river with Triple-A St. Paul in the last two years. The uncertainty around his health obscured his future outlook and called his potential as a starter into question. But he did enough in just seven Spring Training innings last season to show he was healthy and earn one of the final spots in the Twins’ bullpen, then made the absolute most of his first big league opportunity. In 57 relief outings, he allowed just 14 runs and limited hitters to a .251 wOBA, .187 xBA, .269 xSLG, and .232 xWOBA, all of which were in the top 10% of the league. His 34.7% whiff percentage was in the 94th percentile, and his 33.5% strikeout rate was in the 96th. Thanks in part to the trust he quickly earned from Twins manager Rocco Baldelli, he finished second among big league relievers with a 4.56 WPA. Read the rest of this entry »
