After a handful of starts for High-A Greenville, Anthony Eyanson is ready to move up to the next level. The Red Sox are promoting the talented pitching prospect to Double-A Portland, according to Chase Ford of MiLB Central.
Eyanson is just days removed from making his fifth (and perhaps final) start for Greenville at home this past Friday. Going up against Hub City at Fluor Field, the 21-year-old right-hander allowed one hit and three walks (the first three of his professional career) while striking out seven of the 15 batters he faced over 3 2/3 scoreless innings. He threw 67 pitches (37 strikes) and generated 11 whiffs.
In five starts for Greenville altogether, Eyanson posted a minuscule 0.44 ERA with 34 strikeouts to three walks over 20 1/3 innings. Opponents in the South Atlantic League batted just .104/.155/.149 against him. That includes a .114/.139/.114 line from right-handed hitters and a .094/.171/.188 line from left-handed hitters.
Among 26 South Atlantic League pitchers who had thrown at least 20 innings this year entering play Sunday, Eyanson led in batting average against, ERA, FIP (1.46), strikeouts per nine (15.05), strikeout rate (47.9%), swinging-strike rate (22%), WHIP (0.49), and xFIP (1.31). He also ranked third in groundball rate (59.4%) and walks per nine (1.33), and fourth in walk rate (4.2%), per FanGraphs.
Eyanson was selected by the Red Sox with the 87th overall pick in last summer’s draft out of Louisiana State (by way of UC Irvine). The California native received an over-slot $1.75 million signing bonus and stood out in his first spring training with the club by displaying significant velocity gains. He touched triple digits in the Spring Breakout game on March 20 before breaking camp with Greenville in early April.
Since making his pro debut one month ago, Eyanson — throwing from a high release point — has hovered between 95-97 mph and topped out at 98-99 mph with his fastball. The 6-foot-2, 208-pound hurler also incorporates an 86-88 mph slider, a cut-splitter, and a 79-80 mph high-spin curveball into his arsenal, which he described to The Boston Globe’s Alex Speier as “very vertical.”
“I think north-south, and just keeping stuff over the plate and in the zone,” Eyanson told Speier last Thursday. “I’m trying to throw everything in the zone and just let the pitch move on its own, and let the hitter give himself his own problems.”
Eyanson, who does not turn 22 until October, entered 2026 as Baseball America’s No. 13 Red Sox prospect but now has legitimate top 100 buzz surrounding him. He is the first member of Boston’s 2025 draft class to reach Double-A and, like left-hander Payton Tolle a year ago, could be on the fast track to the major leagues.
First, though, comes a new challenge: facing more advanced competition in the upper minors with Portland. The Sea Dogs open a six-game series against New Hampshire at Hadlock Field on Tuesday.
