Antwone Kelly Fantasy Stats

The Pittsburgh Pirates are promoting right-handed pitching prospect Antwone Kelly to the big leagues on Friday, sources told Francys Romero. The 22-year-old was born in Aruba and represented the Netherlands in the 2026 World Baseball Classic. In 54 innings this year with Triple-A Indianapolis, he has struck out 47 batters, and his fastball has reached 101 mph. Per MLB Pipeline, Kelly is considered the team's No. 7 prospect. The 5-foot-10, 238-pounder went 3-4 for Indy with a 4.50 ERA, 1.48 WHIP, and 47:24 K:BB in 54 innings over his 13 appearances (10 starts) on the farm before earning his first MLB call-up. With an electric right arm, there is obvious strikeout upside with Kelly, but he's initially expected to work out of Pittsburgh's bullpen, so fantasy managers shouldn't be looking to spend a grip on him off the waiver wire. Although Kelly throws plenty of strikes, he could be featured in a bullpen role long term, depending on whether he can develop his slider into a true putaway pitch.
