Red Sox promote pitching prospect Jeremy Wu-Yelland to Double-A Portland

The Red Sox have promoted pitching prospect Jeremy Wu-Yelland from High-A Greenville to Double-A Portland, as was first reported by Hunter Noll of Beyond the Monster.

After pitching for China in the World Baseball Classic qualifiers in February, Wu-Yelland opened the 2025 season in Greenville’s bullpen. The 25-year-old left-hander posted a 3.09 ERA (1.96 FIP) with 20 strikeouts to five walks over seven relief appearances (11 2/3 innings) for the Drive. He went 2-for-2 in save opportunities and held opposing hitters to a .222 batting average.

Among 133 South Atlantic League pitchers who came into play Thursday having thrown at least 11 innings, Wu-Yelland ranked fifth in strikeouts per nine innings (15.43), sixth in swinging-strike rate (18.3 percent), seventh in FIP, 10th in strikeout rate (39.2 percent), 13th in xFIP (2.60), 50th in ERA, 64th in groundball rate (43.5 percent), 65th in walk rate (9.8 percent) and batting average against, and 66th in walks per nine innings (3.86), per FanGraphs.

Wu-Yelland was originally selected by the Red Sox in the fourth round (118th overall) of the COVID-shortened 2020 draft out of Hawaii. The Spokane, Wash. native signed for $200,000 and made his professional debut in May 2021 before undergoing Tommy John surgery the following April. He then missed the entirety of the 2022 campaign and was limited to just three outings in the Florida Complex League as a result of being shut down in 2023. He returned to the mound in May 2024 and finished with a 5.67 ERA (3.77 FIP) in 23 appearances (33 1/3 innings) for Greenville last year.

With 54 career innings at the High-A level to his name, the Red Sox likely figured it was time to present Wu-Yelland with a new challenge in the form of a promotion to Portland. The 6-foot-2, 210-pound southpaw has been up to 98 mph with his upper-90s fastball this season and has also featured a cutter and slider. He is currently regarded by SoxProspects.com as the No. 57 prospect in Boston’s farm system, which ranks 31st among pitchers in the organization.

Wu-Yelland, who turns 26 next month, will join a right-handed heavy bullpen mix in Portland that includes the likes of Jack Anderson, Jonathan Brand, Zach Bryant, Yovanny Cruz, Alex Hoppe, Gabriel Jackson, Reidis Sena, and Christopher Troye. It should be interesting to see if he makes his Double-A debut at Hadlock Field before the end of the weekend.
