Red Sox pitching prospects Matt Duffy, Cole Tolbert slated to undergo Tommy John surgery

It appears as though the 2025 season is already over for a pair of intriguing Red Sox pitching prospects.

As was first reported by Andrew Parker of Beyond the Monster, right-handers Matt Duffy and Cole Tolbert have been diagnosed with UCL (ulnar collateral ligament) tears in their pitching elbows. While Duffy’s was described as a full tear, both hurlers are currently scheduled to undergo Tommy John surgery on March 5.

Duffy, 23, was Boston’s fourth-round selection in the 2023 draft out of Canisius University in Buffalo, N.Y. The Ontario native forwent his commitment to transfer to South Carolina for his senior year by signing with the club for an under-slot $350,000 that July. He then spent the entirety of his first full professional season at Low-A Salem in 2024, compiling a 2.83 ERA (3.58 FIP) with exactly 100 strikeouts to 27 walks over 22 appearances (21 starts) and a staff-leading 98 2/3 innings in which opposing hitters batted .223 against him. That includes a sparkling 1.05 ERA (2.25 ERA) in his final nine outings (43 innings) after the calendar flipped from June to July.

Tolbert, meanwhile, was selected by the Red Sox in the 18th round of last summer’s draft out of Ole Miss. In a similar fashion to Duffy, the 22-year-old had been committed to transfer to Troy University for his senior season but instead signed with Boston for an under-slot $50,000 in July. He made his professional debut shortly thereafter and closed the 2024 campaign by posting a 5.56 ERA (3.23 FIP) with 14 strikeouts to six walks in five appearances (three starts) spanning 11 1/3 innings for Salem. Opponents batted .268 against him.

Neither Duffy (who turns 24 in October) nor Tolbert (who turns 23 in December) are currently ranked among Boston’s top 60 prospects by SoxProspects.com. The former was projected by the site to make the jump to High-A Greenville for the start of the upcoming season while the latter was slated to return to Salem. They will now miss all of 2025 and likely part of 2026 depending on the nature of their respective procedures.
