Pirates acquire potential rotation arm from Giants
The Pirates have acquired right-hander Daulton Jefferies from the Giants in exchange for outfielder Rodolfo Nolasco, per Maria I. Guardado of MLB.com. Jefferies had been designated for assignment by San Francisco earlier this week. The Pirates later announced the deal, transferring catcher Jason Delay to the 60-day injured list to open a 40-man spot for Jefferies.
Jefferies, 28, signed a minor league deal with the Giants in the offseason and was added to their roster in the early days of the season. He has since tossed 4 2/3 innings in the majors, though he allowed nine earned runs in that time. His work in Triple-A this year has been much better, with a 3.44 earned run average in 18 1/3 innings, striking out 22.7% of batters faced while giving out walks jst 6.7% of the time.
The fact that Jefferies is even able to take the mound is a feat in itself. He underwent thoracic outlet surgery in June 2022 before requiring a Tommy John procedure that September. Having those two significant procedures in quick succession prevented him from pitching in any official capacity 2023.
Prior to that injury odyssey, he had thrown 56 1/3 innings for the Athletics over the 2020-22 seasons, with a 5.75 ERA in that time. He once had a bit of prospect hype, particularly after throwing 79 minor league innings in 2019 with a 3.42 ERA, 29.2% strikeout rate and 2.8% walk rate.
But his stock stalled out a bit from there. With the minor leagues being canceled in 2020, he was only able to toss two innings in the majors. He spent most of 2021 in Triple-A with a lackluster 4.91 ERA, then the aforementioned injuries came for him the year after.
Jefferies still has an option left, which makes him appealing as a depth starter. The Bucs have Johan Oviedo and Marco Gonzales on the injured list, the former out for the whole season. Paul Skenes is going to make his debut tomorrow, joining a rotation with Jared Jones, Mitch Keller, Martín Pérez, Bailey Falter and Quinn Priester.
Perhaps Jefferies will take over for Skenes in the Triple-A rotation and try to work his way back to the majors. The Pirates could call upon him due to injury or underperformance from one of their other starters in the months to come, though Jefferies will be out of options next year. He came into 2024 with between one and two years of service time, meaning he could be retained well into the future if he continues to hold onto his roster spot.
He lost his spot on the Giants’ roster when that club promoted Mason Black, but the Giants will now get a non-roster prospect in return. The 22-year-old Nolasco is commended for his power but has concerning strikeout problems. He was punched out 34.2% of the time in Single-A last year but also drew walks at a 16% clip and hit 20 home runs. He moved up to High-A this year and is striking out at a 43.7% rate.
He’s clearly going to be a project for the Giants but one they’ll happily take for a guy that got squeezed off their roster. Baseball America ranked Nolasco the #27 prospect in the Pirates’ system last year, giving his power a 70 grade on the 20-80 scale, though noting that he’ll have trouble getting to that power if he keeps getting punched out so often.
As for Delay, he has been on the 10-day IL since early April. He underwent surgery to repair the meniscus in his right knee in the middle of April. It was reported at that time that he would need six weeks before returning to baseball activities. His 60-day clock is retroactive to his initial IL placement, so he can technically be reinstated in early June, though his rehab won’t allow for that.
