Five Future Studs Heading to Everett: The AquaSox Just Got Stacked for 2026

The Everett AquaSox just dropped their 2026 roster, and it is absolutely loaded with Seattle's pipeline gold. Five of the Mariners' Top 30 prospects are heading to High-A, including three of the top ten. This is the kind of talent infusion that gets you excited about where the organization is headed, and honestly, the AquaSox are going to be must-watch baseball this summer.

The Speed Demon and the Shortstop Are Back

Jonny Farmelo, ranked number six in the Mariners' system, is returning to Everett after a brutal couple of years. The dude tore his ACL in 2024 and dealt with a stress reaction in his ribs in 2025, which absolutely tanked his plate appearances early in his pro career. But here's the thing: when he got a long look with the big-league club this spring, he reminded everyone why they call him "Jonny Ferrari." His speed is elite, his walk rate is solid, and his raw power is legit. He just needs to tighten up his bat to ball skills and stay healthy. If he does, watch out.

Shortstop Felnin Celesten, the seventh-ranked prospect, is also back. Like Farmelo, staying on the field is his main mission, but the defensive improvements are real. His strikeout rate spiked over a third last year at Everett, and the power got swallowed up in that heavy Pacific Northwest air. But this spring he was making the routine plays and the tough ones too. The switch-hitter looks like he could actually stick at short full-time now.

A Catcher Who Could Move Fast

Luke Stevenson, the Mariners' eighth-ranked prospect, is a newcomer to Everett. The 21-year-old catcher is young for a college product but already has experience commanding a staff. Here's where it gets interesting: scouts are divided on Stevenson. Some see an average defensive catcher who chases power. Others, like yours truly, see a potential power and defense threat at a premium position reminiscent of a young Cal Raleigh. Stevenson absolutely tore up the Cal League, and if he can match what Raleigh did at High-A in 2019, he could completely shift the national conversation around his prospect stock.

Rounding out the Top 30 prospects heading to Everett are outfielder Carlos Jimenez, ranked 21st, making his High-A debut after two years in Modesto, and right-handed reliever Lucas Kelly at number 29. Kelly is a sidearm guy who was drafted in 2025 and already punched out the final out of Everett's championship Game 4 against Eugene last season.

The AquaSox are ready to rake in 2026. Get to Funko Field early.
