2026 Projections
2026 Fantasy Outlook
Defrank logged a 3.19 ERA, 1.29 WHIP and 34:10 K:BB in 31 innings across 10 starts in the Dominican Summer League. Arguably the top pitching prospect from the DSL last year, the 6-foot-5 Defrank already touches triple digits with his fastball and features an advanced changeup to go with an average slider. Defrank, who signed with the Marlins for $560,000 on Jan. 15, 2025, has a chance to rocket up prospect lists this year if he stays healthy and throws enough strikes. Read Past Outlooks
