In an age when immediate results for prospects are weighed heavily in public rankings and coverage, itâ€s easy to lose sight of the reason the minor leagues exist. Developing players is paramount to organizational success these days, and the ability to make players better has become a larger investment for teams.

Pitchers, in particular, can see quick results from a few months of work. And while there are many ways a pitcher can improve—new pitches, improved shapes or simply training command—the easiest way to improved results is tried and true—adding velocity.

With that in mind, we’ve compiled a list of every minor league pitcher who 1.) threw 100 or more fastballs in each of the last two seasons and 2.) added at least 2 mph of velocity in 2025. While not all of these players enjoyed more productive seasons because of their velo gains, most of them did. And there are quite a few notable breakouts to be found, as well.

Baseball America subscribers can read the full list below, followed by takeaways on key players.

Top Fastball Velocity Gainers For 2025

Velocity Gainer Takeaways

• The top of the list is littered with complex-level players. Andres Herrera, Irvin Gonzalez and Jose Ortega are all Dominican Summer League repeaters, but each have seen gains in their second or third seasons on the circuit.

• Astros righthander Hudson Leach went undrafted out of Miami (OH) back in 2023 and saw 4+ mph velocity gain in 2025. The jump in stuff coincided with his best season as a professional, as he reached Triple-A by the end of the season.Â

• DSL repeater Yoesmerli Beltre enjoyed a breakout campaign in his second summer with the Padres. He saw a jump in fastball velocity, and his results improved accordingly. Over 19 appearances spanning 21.2 innings, Beltre struck out 26 batters while pitching to a 1.66 ERA.

• The Astros signed Javier Perez out of Mexico in January 2024, and is his first season stateside he saw a 4+ mph jump in average fastball velocity. He made 19 appearances between the Astros’ Florida Complex League affiliate and Low-A Fayetteville, pitching to a 2.88 ERA with 70 strikeouts against 11 walks in 68.2 innings.Â

• Jaitoine Kelly saw a 4+ mph jump in 2025 and had a solid season in his first stateside campaign with the Diamondbacks. Over 37 innings in 2025, the 18-year-old righthander from Aruba struck out 28 batters.Â

• Back in 2020, Carter Baumler was a later-round upside pick by the Orioles. Itâ€s taken a few years for things to gel, but Baumler looks like heâ€s back on an MLB trajectory after moving to the bullpen last season. The 23-year-old righty saw his average fastball velocity jump from well below-average to above-average this season, and it now sits 95+ mph. In turn, Baumler pitched to a 2.04 ERA with 46 strikeouts over 39.2 innings.
