Marlins Option Gusto Back to Triple-A Jacksonville After Scoreless MLB Stint

Ryan Gusto, the 27-year-old right-hander on Miami's 40-man roster, turned one scoreless inning and a hold into a clear organizational signal before the Marlins optioned him back to the Jacksonville Jumbo Shrimp on April 9.

The whole sequence ran on Pete Fairbanks' paternity timeline. When Miami's closer stepped onto the paternity list ahead of the club's series against the Cincinnati Reds, the Marlins recalled Gusto from Jacksonville to fill the vacancy. He delivered a scoreless frame, collected the hold on Wednesday, and then watched Fairbanks return to the active roster. The roster math resolved itself in roughly 72 hours.

One inning. One hold. Zero runs. That's the entire ledger from Gusto's big-league cameo, and it reads better than it looks for a pitcher who has been limited by a right shoulder impingement since arriving in Miami via trade from Houston last July. Going scoreless in a live big-league situation matters more than the raw volume suggests.

Gusto arrived on July 31, 2025, when Miami sent outfielder Jesús Sánchez to Houston in exchange for Gusto, infielder Chase Jaworsky, and outfielder Esmil Valencia. Marlins president of baseball operations Peter Bendix called Gusto "an above-average Major League starting pitcher right now" at the time of the deal, adding that he saw "a lot more meat on the bone." The shoulder impingement that followed clipped his Miami 2025 stretch to three starts and a 9.77 ERA, a far cry from the 7-4 record and 87 strikeouts over 86 innings he posted with Houston earlier that season.

The 2026 Triple-A debut suggested a healthier arm. Gusto opened the Jumbo Shrimp season with five innings of three-run ball and seven strikeouts, the kind of outing that earns a phone call when a big-league bullpen gets thin. Four Miami relievers, Anthony Bender, Calvin Faucher, John King, and Andrew Nardi, had already worked back-to-back days when Gusto received the original recall, which tells you exactly how quickly the math changes in early April.

Because Gusto remains on the 40-man roster, Miami can bring him back without exposing him to waivers, making him the obvious first call when the bullpen needs a right-handed depth piece. That standing is not guaranteed to hold, though. It depends on what he shows over his next two or three appearances in Jacksonville.

Baseball America grades Gusto's changeup and control at 55, with his slider at 50. Those are his two best separators, and the question scouts and the Miami coaching staff will be watching in his next few Jumbo Shrimp outings is whether he can land that slider consistently in multi-inning stints under game-speed conditions rather than in isolated one-inning bursts. A reliever who sequences a 55-grade changeup with sharp slider command across back-to-back clean appearances looks like a real late-inning asset. A reliever who can only do it once looks like a short-stint fill-in, which is exactly what this week's transaction confirmed him to be.

Fairbanks is healthy, the bullpen spot is filled, and Gusto is back with the Jumbo Shrimp. The next opening probably appears the moment another Miami arm hits the injured list, which is how April works in every bullpen across the league. When it does, Gusto's scoreless ledger from Wednesday makes him the first name on the whiteboard.
