On July 13, 2025, the Boston Red Sox selected Anthony Eyanson in the third round of the MLB Draft. The Red Sox paid him overslot value, and fans were excited about what could become of him if the pitching lab could work its magic and add some velocity to his fastball.
Fast forward to the Spring Breakout game, and we saw the off-speed and breaking stuff continue to look fantastic. Meanwhile, the fastball (which was sitting in the low 90s at LSU) topped out over 100 MPH in his lone inning that game.
That may have been just one inning in an exhibition game showcasing prospects, but it set the tone for Eyanson’s 2026 season. On May 19, it reached a new peak.
Eyanson began the season in High-A, but didn’t stay there long. He posted a 0.44 ERA, .104 BAA, and 0.49 WHIP in five starts before being promoted to Double-A. The right-handed pitcher struck out 34 batters and walked only three in 20 1/3 innings.

In his first Double-A start on May 10, Eyanson allowed one run on three hits over four innings. He struck out four batters and walked one. It was more of his usual dominance.
The 21-year-old didn’t make another start until May 19. A nine-day layoff might throw off someone’s timing, right? Not Eyanson.
He tossed five shutout innings. He fanned four batters and allowed three walks. Oh, and he didn’t allow any hits. It’s the second time in his young career that Eyanson didn’t allow a hit in a start (April 11 in High-A against the Hub City Spartanburgers over 4 1/3 innings).
The start of Tuesday was impressive for a few particular reasons. First of all, Eyanson is in Double-A now. The competition is getting serious. Second, he’s working on some pitches. Eyanson’s best pitches are his curveball, slider, and fastball. His changeup has flashed potential as well. According to Ian Cundall of SoxProspects and Baseball America, he was not only mixing in his new cutter but leaning on it.
We’ve already seen Eyanson dominate to a laughable degree. Adding pitches to his repertoire and remaining unhittable seems like the kind of story your grandfather tells you about a kid from his hometown that he swears was better than Bob Gibson, but he got hurt in high school and never got drafted. Well, the Red Sox drafted Eyanson, and it appears they once again hit the jackpot.
