FORT MYERS, Fla. — Do the Red Sox have a Big Three, v. 2.0? Such a claim is probably premature, but the team does have a trio of head-turning mound talents who were drafted together last summer and will now start their minor league careers with the same affiliate to begin 2026.

Righthanders Kyson Witherspoon, the Red Sox’ first-round selection out of Oklahoma in 2025, Marcus Phillips (Competitive Balance Round A, Tennessee), and Anthony Eyanson (third round, LSU) will all start the 2026 season in High-A Greenville, according to a major league source.

All three displayed eye-popping ability in the Spring Breakout Game. Witherspoon has the most complete mix, featuring a fastball now averaging 97 miles per hour and touching 99, curveball, cutter, slider, and splitter. This spring, he showed improved fastball velocity and better shape to his splitter as he looks for a weapon against lefties.

Eyanson was the breakout performer of the Sox system this spring. After he typically worked in the low-90s while topping out at 97 m.p.h. in college, he made huge gains on a professional strength program, culminating in an electrifying Spring Breakout game performance in which he touched 100 m.p.h. for the first time in his life, averaged 99.2 m.p.h. on his fastball, and struck out the side with three curveballs.

Get Starting Point

A guide through the most important stories of the morning, delivered Monday through Friday.

Phillips is at an earlier stage of his pitching career. He was a two-way player through high school and a year of junior college, but his tremendous strength (he touched 101 m.p.h. in college, but more often sits in the mid-90s with his two-seam fastball) and funky, low-three quarters angle (somewhat reminiscent of Justin Masterson), cutter, and slider create considerable confusion in hitters.

Witherspoon and Eyanson were locks to start in Greenville, while Phillips, because of his inexperience, was a possibility for Low-A Salem to start the year. However, the closeness of the three — they lived together in Fort Myers both after being drafted last summer/fall and again this spring — convinced the Sox that there is a potentially rare opportunity in which the relationship of players can help push each other in their training and development.

The Sox seemingly benefited from the position player versions of the Big Three in 2024, when the closeness of Roman Anthony, Marcelo Mayer, and Kyle Teel (and eventually Kristian Campbell) seemingly served as a developmental catalyst for three top prospects. Now, they’re hoping the same will prove true of a gifted group of pitchers at the start of their careers.
