The Marlins are calling up pitching prospect Robby Snelling. He’ll be selected to the roster and will start Friday against the Nationals. They have an open 40-man spot after designating Chris Paddack for assignment earlier this week, so they will only need to open an active roster spot for him. Manager Clayton McCullough announced the news to reporters, including Daniel Álvarez-Montes of El Extra Base.
The Snelling promotion has been expected since not long after Paddack’s DFA. He and fellow lefty Braxton Garrett were possibilities to take the ball Friday in place of Paddack, but Garrett tossed 80 pitches in a start for Triple-A Jacksonville last night, strongly hinting that Friday would be Snelling’s big league debut. The team has now made that official.
Selected by the Padres with the No. 39 overall pick back in 2022, Snelling made his way to the Marlins organization as part of the return in the deadline trade sending relievers Tanner Scott and Bryan Hoeing to San Diego. His stock was down a bit at the time of the swap, but he’s rebounded nicely with the Marlins organization — so much so that Baseball America ranked him 26th on this morning’s refresh of their top-100 prospect rankings.
The 22-year-old Snelling has been excellent this year in six Triple-A starts, recording a 1.86 ERA and a mammoth 40% strikeout rate — albeit against a concerning 13.6% walk rate. He’s kept 57% of batted balls against him on the ground. Snelling was also lights out in 11 Triple-A starts last year (1.27 ERA — 2.51 overall ERA between Double-A and Triple-A). At this point, he seems more than ready for a look in the majors, even with the sub-par command.
Snelling, listed at 6’3″ and 210 pounds, works primarily off a four-seam fastball that averages just over 94 mph and a curveball that sits 82-83 mph. He mixes in an occasional changeup and slider, but the four-seamer/curveball combo has accounted for more than 80% of his pitches in 2026. Snelling’s four-seamer and curveball both drew plus grades (60) on BA’s scouting report, while his lesser-used changeup and slider still garner above-average (55) ratings on the 20-80 scale.
More to come.
