The Marlins have claimed right-hander Nick Nastrini off waivers from the White Sox and optioned him to Triple-A Jacksonville, reports Kevin Barral of Fish on First. Righty Max Meyer, who recently underwent season-ending hip surgery, was transferred to the 60-day injured list to open a 40-man roster spot.
There wasn’t any previous indication that the White Sox had removed Nastrini from their 40-man roster, but it appears they quietly put him on waivers recently. Presumably, they hoped to pass him through unclaimed but the Marlins swooped in to grab him. Chicago’s 40-man roster count drops to 38.
The young righty has not been putting up good numbers this year, which is perhaps why the Sox felt there was a chance no one would claim him. He has thrown 44 1/3 Triple-A innings on the year with a 7.51 earned run average. His 22.7% strikeout rate is fine but he has walked opponents at a massive 18.5% clip.
The Marlins bumped him from the rotation to the bullpen in May. That didn’t help matters much. In his most recent 17 innings, he has a 7.94 ERA and massive 23.2% walk rate, though with an intriguing 30.5% strikeout rate.
Despite this year’s rough results, the Marlins have grabbed him. They had a roster spot open and Nastrini has shown promise at times, though mostly in that high-strikeout, high-walk style. From 2022 to 2024, he threw 316 1/3 minor league innings with a 4.35 ERA, 29.6% strikeout rate and 11.6% walk rate. He also tossed 35 2/3 major league innings for the Sox last year, though with poor results. He had a 7.07 ERA, 14.9% strikeout rate and 20.9% walk rate.
He can still be optioned for the rest of this year and one additional season. The Marlins are one of the few clubs clearly not in contention at the moment, so they are an understandable landing spot for a project like Nastrini.
