How did Red Sox pitching prospect Jose Bello (part of return for Rafael Devers) fare after trade?

After writing about James Tibbs III over the weekend, it feels like an appropriate time to examine how the other prospect the Red Sox acquired from the Giants in the Rafael Devers trade — Jose Bello — fared in the wake of the blockbuster deal being made in June.

Unlike Tibbs, Bello was not subsequently flipped at the trade deadline the following month and still remains in the organization. The 20-year-old right-hander was originally signed by the Giants for $47,500 as an international free agent coming out of Santo Domingo in January 2023. He spent the better part of his first two professional seasons in the Dominican Summer League before making his stateside debut in the Arizona Complex League last July.

Bello returned to the ACL Giants for the start of his 2025 campaign and posted a 2.00 ERA (1.89 FIP) with 28 strikeouts to three walks in eight relief appearances (18 innings) before being flipped to the Red Sox alongside Tibbs, Kyle Harrison, and Jordan Hicks on June 15. The young righty made the trek eastward and joined Boston’s Florida Complex League affiliate, compiling a 3.14 ERA (2.59 FIP) with 16 strikeouts to eight walks across his next five outings (one start) spanning 14 1/3 innings. He then received a promotion to Low-A Salem on July 25.

Tasked with his first full-season assignment, Bello pitched to a 3.09 ERA (4.04 FIP) with 17 strikeouts to 15 walks in seven appearances (four starts) totaling 23 1/3 innings for Salem. He ended the year on a high note in his September 7 start against Fayetteville, giving up just one unearned run on three hits, two walks, and four strikeouts over five strong frames.

Overall, Bello produced a 2.75 ERA (2.97 FIP) with 61 strikeouts to 14 walks over 20 appearances (five starts) between the ACL, FCL, and Salem in 2025. Opposing hitters batted .210 against him in 55 2/3 total innings across the three levels. That includes a 3.11 ERA (3.49 FIP) and a .234 opponents’ batting average across 37 2/3 innings after being traded from the Giants to the Red Sox.

Listed at 6-foot-1 and 164 pounds, Bello throws from a three-quarters arm slot and creates deception with his cross-body delivery. As noted in his SoxProspects.com scouting report, the athletic hurler features a four-pitch mix that consists of a 92-94 mph fastball that tops out at 96 mph, a 90-92 mph cutter, an 83-86 mph slider, and a seldom-used upper-80s changeup.

Bello, who does not turn 21 until May, is currently regarded by SoxProspects.com as Boston’s No. 54 prospect, which ranks 32nd among pitchers in the organization. Barring a trade or other surprise move this winter, he is projected by the site to return to Salem for the start of the 2026 season.
