The Miami Marlins claimed pitching prospect Nick Nastrini off of waivers on Tuesday. The 25-year-old was with the Chicago White Sox organization and ranked No. 24 on the team's top prospect list, making nine appearances for the club last year, posting a 7.07 ERA, 1.91 WHIP, and more walks (36) than strikeouts (26) in 35 2/3 innings pitched. The righty had made 20 appearances (six starts) at Triple-A Charlotte in 2025, recording a 7.51 ERA, 1.69 WHIP, and a 4.3 percent K-BB%. The 6-foot-3 hurler has been assigned to Triple-A Jacksonville, and although the numbers don't look great, he's a former fourth-rounder and maybe a new environment will unlock his true potential. He's off the fantasy radar in all formats, though.

Chicago White Sox pitching prospect Nick Nastrini tossed six shutout innings on Tuesday evening against Triple-A Scranton/Wilkes-Barre. In this outing, Nastrini allowed just two hits and two walks. He struck out six. This was a much-needed bounce-back for Nastrini as he posted an underwhelming 6.89 ERA with a 1.66 WHIP across his first four starts of the season (15 2/3 innings). During this stretch, he held a modest 12:9 K:BB and allowed three long balls. Last summer, Nastrini made his MLB debut but struggled at that level as he posted a 7.07 ERA with a 1.91 WHIP across 35 2/3 innings. He was in the mix to earn a spot on the Opening Day roster but ultimately fell short in the competition. Fantasy managers should keep an eye on his progression at Charlotte as he could be in the mix to return to the majors if he can build off this strong start.
