Antwone Kelly

22-Year-Old PitcherRP
Pittsburgh Pirates AAA
2026 Fantasy Outlook
A 5-foot-10 Aruban righty, Kelly boasts an impressive combination of fastball velocity (sits 97 mph, touches 101 mph) and control (7.7 BB% in 2025), which led to the Pirates adding him to the 40-man roster this offseason. Kelly dominated at High-A (23.0 K-BB%) and was quite good at Double-A after a midseason promotion, logging a 3.00 ERA, 1.17 WHIP and 46:16 K:BB in 48 innings over 11 starts. His 70-grade fastball is his only plus pitch, and while his changeup is good enough, he lacks a standout breaking ball. Kelly, who doesn't turn 23 until September, will continue to refine his craft in the upper minors in 2026. He could be a mid-rotation starter if his slider comes along with the fallback option of late-inning reliever. Read Past Outlooks
Signed a one-year contract with the Pirates in March of 2026.
Sent back to Triple-A
PPittsburgh Pirates  AAA
June 13, 2026
The Pirates optioned Kelly to Triple-A Indianapolis on Saturday, Danny Demilio of PittsburghBaseballNow.com reports.
Analysis
Kelly will head back to the minors after giving up two earned runs in 2.1 innings during his MLB debut Friday. The 22-year-old owns a 4.50 ERA and 1.48 WHIP through 54 frames at Indianapolis while working primarily as a starter and could be called upon to make additional appearances for the Pirates later in the season -- likely as a long reliever. Isaac Mattson was recalled from Triple-A to fill the open spot in Pittsburgh's bullpen.
