Double-A Chesapeake: OF Thomas Sosa (O’s No. 18 prospect)
Sosa got a small taste of Double-A late last season, playing 11 games for Chesapeake and hitting .158 (6-for-38) with a .562 OPS. The Villa Mella, Dominican Republic, native returned to the level to begin 2026, and he’s faring much better.
The 21-year-old outfielder is hitting .280 (14-for-50) with an .828 OPS through 12 games. Sosa hasn’t homered since his season debut on April 2, but that should change soon, as his 50-grade power is among his best tools.
Although Sosa isn’t likely to reach the big leagues this year, his strong play could earn him a promotion to Triple-A later this summer.
High-A Frederick: RHP JT Quinn (O’s No. 19 prospect)
There’s been a lot of hype surrounding Quinn and fellow 2025 draftee Joseph Dzierwa, a pair of intriguing pitching prospects headlining the Keys’ rotation. They’ve each gotten off to an impressive start in their debut professional seasons, but Quinn has just been dominant.
Through three starts, the 21-year-old right-hander has a 0.64 ERA and a 0.79 WHIP to go with 23 strikeouts and three walks over 14 innings. His lone run allowed came in his pro debut on April 4, as he has tossed 9 2/3 scoreless frames over his past two starts.
Keep an eye on Frederick’s schedule to see when Quinn will pitch this week, because the 2025 Competitive Balance Round B pick is delivering must-watch outings every time he takes the hill.
