The Boston Red Sox signed a little-known pitcher to add more depth to their pitching staff as spring training gets underway.
The Red Sox signed 23-year-old right-handed pitcher Harrison “Harry” Blum to a minor league contract this week, as reported by Baseball Now’s Andrew Parker. Boston later confirmed Blum’s signing on its official transactions page on Thursday.
Blum went undrafted in 2025 after spending five seasons playing college baseball. The 6-foot-7 hurler spent the majority of his college career in Division III with Luther College, but transferred for his final season of college eligibility to Division II to play for Augustana University in Sioux Falls, South Dakota.
Boston has heavily bolstered its pitching staff in the big leagues this offseason, bringing in Sonny Gray and Ranger Suárez, but continues to add talent to the team’s farm system as well. Blum is not the first towering pitcher the Red Sox have acquired in recent memory, with players like Garrett Crochet, Johan Oviedo and Payton Tolle all being 6-foot-6 or taller.
After spending much of his college career as a starting pitcher, Blum transitioned into more of a bullpen role at Augustana, posting a 4.91 ERA with 48 strikeouts in 47 2/3 innings pitched. The 23-year-old has also added nearly five mph to his fastball in the last eight months.
Despite only ever facing lower-level college hitters, Blum is getting a shot at professional baseball. The right-handed pitcher is projected to start the season in Low-A Salem, but he could be an interesting player in the minor leagues this season.
