Pirates claim pitcher Dugan Darnell

The Pittsburgh Pirates announced that they have claimed right-hander Dugan Darnell off waivers from the Rockies. He was immediately transferred to the 60-day injured list, so the Bucs didn’t need to open up a 40-man roster spot. In late August, it was reported that Darnell would be undergoing surgery to address a torn labrum in his hip, a procedure with a recovery timeline of about eight months.

There was no previous indication that the Rockies had removed Darnell from their roster. It’s common at this time of year for teams to place players on waivers, as many clubs are facing roster crunches. The 60-day IL goes away five days after the World Series, so players need to retake 40-man roster spots. Some breathing room is created by others reaching free agency but teams often need to clear space. Even if a team doesn’t need space now, having it is valuable throughout the winter for other moves, including protecting guys from the Rule 5 draft.

RosterResource projected the Rockies to have 41 guys for 40 roster spots at the beginning of the offseason, including Darnell. It seems Colorado tried to open a spot by passing Darnell through waivers, but the Pirates intervened. The Pirates will face a crunch of their own, as RosterResource projects them to have 42 guys for 40 spots, not including Darnell. The Bucs will therefore have to do some clearing in the coming days.

For now, they are bringing a fresh relief arm into the system. Darnell, 28, was signed by the Rockies as an undrafted free agent in 2021. He got a very limited big league debut this year. He was called up on Aug, 1, but then left hip inflammation put him on the IL three weeks later. In that debut, he tossed 11 2/3 innings over nine appearances. He allowed five earned runs on ten hits and seven walks while striking out five.

That’s a small sample of work, so presumably the Bucs are also putting some stock in his minor league track record. He has thrown 255 1/3 innings on the farm with a 3.74 earned run average, 30.6% strikeout rate and 9.9% walk rate. That includes 53 2/3 Triple-A innings in 2025, pitching in the hitter-friendly Pacific Coast League, with a 3.19 ERA, 28.8% strikeout rate, 8.7% walk rate and 43.5% ground ball rate.

Given Darnell’s surgery timeline, he likely won’t be available until the middle of next year. Perhaps the Bucs will keep him on the 40-man through the winter and then put him on the 60-day IL again once it returns in spring training. It’s also possible the Bucs try to pass him through waivers unclaimed during the offseason, therefore keeping him as non-roster depth.
