Triple-A Spring Statcast Standouts: Exit Velocities, Pitch Speeds, Whiff Rates

Drake Baldwin’s Triple-A Statcast profile reads like a spring-training calling card: a 92.8 mph average exit velocity, a 53.1% hard-hit rate, a 10.6% barrel rate, an xBA of .304 and an xSLG of .516 based on his quality of contact. "MLB.com’s Statcast roundup (published March 3, 2026) examines early spring training performances through advanced tracking data, highlighting players — both established Major Leaguers and top prospects — who produced extraordinary exit velocities, pitch speeds, spin/whiff metrics and sprint speeds."

The expansion of Minor League Statcast is central to that advance in early evaluation, a development Milb flagged bluntly: "Thanks to the Minor League Statcast data now available there's Statcast tracking for all Triple-A Games, a significant number of Single-A games, Arizona Fall League games and more we already know a lot about top prospects' tools before they even get to Spring Training." That depth of tracking is why Triple-A metrics are showing up in big-league conversations this spring.

Milb’s prospect framing places Baldwin in context: the 23-year-old lefty swinger was described as the Braves' top prospect entering 2025, listed as MLB's No. 63 prospect overall and the No. 7 catching prospect. Milb summed his profile succinctly: "Just an all-around excellent hitter." Those contact numbers from Triple-A are the hard evidence behind that label and are the kind of Statcast signals clubs reference when deciding whether a prospect starts in Triple-A or breaks camp with a big-league club.

"Let's get to the pitchers." That transition in the roundup is warranted when you consider Bubba Chandler’s Triple-A profile. The 22-year-old ranked as MLB's No. 15 prospect entering Spring Training 2025 and posted 54 strikeouts in 39 1/3 innings at Triple-A. The 22-year-old has a great power arsenal, with a four-seam fastball that averaged 96.8 mph at Triple-A, a changeup that averaged 88.8 mph and a slider that averaged 86.8 mph. All three of those pitches produced strikeout rates over 30%, the kind of per-pitch whiff production that forces clubs to accelerate promotion conversations.

Other names appear in the compiled excerpts but without the Statcast detail supplied for Baldwin and Chandler: JJ Wetherholt, SS, Cardinals; Jac Caglianone, 1B, Royals; and Jacob Misiorowski, RHP, Brewers, were all listed in the source material. The Milb pieces included a lineup approach, "Here are 10 top prospects at Spring Training 2025 five hitters and five pitchers who lit up Statcast last year," but the supplied excerpts do not include the complete metric sets for those other prospects.

There is also a timing wrinkle to reconcile: Milb’s excerpts tie several prospect rankings and phrases to entering 2025, while MLB.com’s roundup is dated March 3, 2026. Those date references do not align and should be resolved before treating the rankings and Statcast lines as contemporaneous for 2026 roster decisions. Still, the takeaway is clear: with Statcast tracking now covering all Triple-A games and MLB.com highlighting early spring standouts, concrete numbers like a 92.8 mph average exit velocity or a 96.8 mph four-seam are becoming primary evidence in how teams sort Triple-A depth and shape their preseason rosters.
