On Thursday, we looked at the top-performing hitters for the month of August. In today’s follow-up article, we’ll dig into 10 pitchers who wowed with their performance metrics over the minors leagues’ final full month of play.
We’ll be looking into each pitcher’s background and quality of their season overall before discussing what they did in August. Beyond just the results, we’ll examine how each player to crack the list achieved their results based on their arsenal quality, velocity, movement and command.
Daniel Eagen, RHP, Diamondbacks
A 2024 third-round pick out of Presbyterian, Eagen has enjoyed a strong professional debut by pitching well over 19 starts with High-A Hillsboro before seeing promotion to Double-A Amarillo a few weeks ago.
While Eagen has been consistently good throughout 2025, his August has been phenomenal. Over four starts, he has pitched to a 0.73 ERA, striking out 34 batters to six walks over 24.2 innings. After three strong starts to begin the month with High-A Hillsboro, Eagen was promoted to Amarillo and made his Double-A debut on Aug. 22, tossing 7.2 scoreless innings with two hits, a walk and eight strikeouts.
Eagen mixes four pitches led by a four-seam fastball with plus ride. The fastball sits 92-93 mph and touches 96 at peak, but it generates a fair amount of swing-and-miss. His primary secondary is a low-80s curveball that generates a high rate of whiffs. He’ll also mix in a harder slider in the 83-84 mph range and an occasional changeup. Eagen has at least average command of his arsenal with the ability to generate outs in a variety of ways, and he drives a higher groundball rate against his two breaking ball shapes.
Amarillo and the Texas League remain two of the more difficult environments for pitchers in all of professional baseball. If Eagen handles this challenge over the final starts of his season, he should enter the offseason with substantial helium.
Jarlin Susana, RHP, Nationals
Susana was acquired by the Nationals in the Juan Soto trade with the Padres back in 2022. One of the hardest throwers in baseball, he will sit upper 90s on two variations of his fastball while also mixing in a hard high-80s/low-90s slider.
Over five starts this month, Susana pitched to a 1.52 ERA across 23.2 innings. He showed improved command throughout August, walking only 10.1% of opposing hitters—a mark below his career average. Over those 23.2 innings, Susana racked up 44 strikeouts…
