Boston Red Sox Top Prospects: No. 10 Anthony Eyanson
Selected in the third round of the 2025 draft out of Louisiana State University, Anthony Eyanson may end up being one of the biggest steals for the Boston Red Sox in recent years. Eyanson completed his junior season at LSU by winning the national championship, ultimately garnering attention as a top-50 draft prospect. As the Saturday starter for LSU, Eyanson made 20 appearances, 18 of them starts, and went 12-2 with two saves across 108 innings. He was dominant on the mound, allowing just 36 earned runs.
Things would not work out perfectly for Eyanson, however, as the right-hander slid to the third round, where the Red Sox selected him at the 87th pick.
Eyanson is a very intriguing pitching prospect, one who continues to fit in with Craig Breslow’s desire to acquire pitchers who are big (he stands 6-foot-2 and weighs 210 pounds) and have good extension (6.41 feet). The right-hander has a polished arsenal made up of a fastball, slider, curveball and changeup, and he’s got strong control of each of those offerings.
His fastball routinely sat between 92 and 94 mph in college, occasionally topping out at around 97 mph. However, in his first week of spring training, the right-hander managed to get it up to 98 mph. His slider has more vertical break to it instead of horizontal (i.e., more traditional power slider than a modern sweeper) and despite a lower spin rate, it can miss bats. It also manages to generate a high chase rate despite not landing in the zone all that often. In college, the slider managed to produce a 52% whiff rate and could become his main “out pitch” in professional baseball.
Eyanson’s curveball is thrown competitively, but despite a good amount of vertical depth, it fails to miss as many bats as would be expected. It is used more often against left-handed batters. Finally, his changeup may be his weakest pitch, as he fails to consistently land it in the strike zone, and he may need to adjust the low-80s offering as he graduates various levels in the system.
In college, Eyanson showed an ability to rack up strikeouts, finishing the 2025 season with 152 in just 108 innings. There is no reason to believe that should change once he gets his first taste of minor league baseball thanks to his fastball, slider and curveball. Early on in spring training, he has looked good on the backfields while throwing live at-bats.
One of Eyanson’s best traits is his ability to limit free passes. While his strikeouts were well documented (33.9% rate), he managed to walk just 36 batters with LSU, good for an 8.0% walk rate. Thanks to this, Eyanson already has a high floor and comes with little reliever risk. Should he manage to maintain the increased velocity he’s showing with his fastball across the entire season, he would project as a mid-rotation arm.
Eyanson is likely to open the year in High-A Greenville, but thanks to his strike-throwing ability along with his already-polished arsenal of pitches, he could be promoted to the upper levels of the organization quickly. The right-hander is confident in his own abilities and is entering 2026 with a determination to prove he should have been taken within the first two rounds of the draft. He’ll be an interesting pitcher to watch, especially if he can find an arm-side pitch to throw to left-handed hitters.
