Red Sox Prospect Eyanson Dominates, Earns Double-A Call-Up
4 May
Summary
- Eyanson promoted to Double-A Portland after dominant five starts.
- He boasts a 0.44 ERA with 34 strikeouts in 20.1 innings pitched.
- Eyanson shows a 'relentless obsession' with improvement, per pitching director.

Boston Red Sox pitching prospect Anthony Eyanson is making a swift ascent through the minor league system, now positioned just two steps away from the major leagues. The team's No. 9 prospect has been promoted to Double-A Portland after a dominant start to his professional career with High-A Greenville.
Eyanson, who made his debut this season after being selected in the third round of the 2025 MLB Draft, has showcased incredible skill. In his initial five starts, he recorded a mere 0.44 earned run average with 34 strikeouts in 20.1 innings pitched. Notably, he achieved a 27-to-0 strikeout-to-walk ratio over his first 16.2 innings.
The 21-year-old's rapid progression is faster than that of notable 2025 pitching prospects Payton Tolle and Connelly Early. Red Sox director of pitching Ben Buck described Eyanson's drive as a "relentless obsession" to improve, a trait he finds exceptionally rare and impactful on the pitcher's performance and work ethic.
MLB.com projects Eyanson's big league debut for 2028, but his current trajectory suggests this timeline could be significantly accelerated if his performance continues at this exceptional pace.
