2025 Fantasy Outlook
The Marlins acquired Snelling as part of the deadline deal that sent Tanner Scott and Bryan Hoeing to the Padres. The 20-year-old lefty had a mediocre 10.3 K-BB% prior to the trade and had a 19.7 K-BB% with the Marlins' Double-A affiliate and then fanned seven over six innings of one-run ball in his lone Triple-A start. He has three average to above-average offerings but needs to hit his spots, particularly with his low-90s fastball. Snelling was the youngest qualified starter at Double-A and has now logged 100-plus innings in back-to-back minor-league campaigns -- an impressive feat for a pitching prospect heading into his age-21 season. Snelling is still young enough to improve his pitches and his craft, and the early returns suggest the change of scenery helped get him back on track. He'll be one of the youngest players at Triple-A in 2025 and could spend a couple months in the big-league rotation to close the year. Read Past Outlooks

Nothing left to prove at Triple-A

Snelling allowed one run on seven hits over seven innings for Triple-A Jacksonville on Wednesday, striking out a career-high 13 without walking a batter.
Analysis
The lack of a spot on the 40-man roster seems to be the only thing keeping Snelling from making his major-league debut in 2025. The 21-year-old southpaw has delivered seven straight quality starts at Triple-A, fanning double-digit batters three times during that stretch while producing a 1.24 ERA, 0.89 WHIP and 62:9 K:BB through 43.2 innings. The Marlins have so far declined to promote Snelling despite having six starting pitchers on the IL at the moment, but despite the team's apparent desire to delay starting his service-time clock, he clearly has nothing left to learn in the International League.

2024 Fantasy Outlook
Snelling had one of the more impressive full-season debuts of a prep pitcher draftee in recent memory. The No. 39 overall pick in 2022 logged a 1.82 ERA, 1.12 WHIP and 118 strikeouts in 103.2 innings while climbing from Single-A to Double-A as a 19-year-old. A four-star recruit as a linebacker, Snelling gets rave reviews for his makeup and competitiveness. He has a muscular 6-foot-3, 210-pound frame and sits in the mid-90s with his high-spin fastball. The young lefty has a plus spike curveball and two potentially average pitches in his changeup and slider. His pitchability, command and fastball/curveball combination give him a reasonable mid-rotation floor and a chance to exceed that projection with further development of his changeup or slider. The Padres lack quality starting pitching depth, so Snelling could rapidly ascend to the big leagues if he performs early in his age-20 season.
