The Boston Red Sox farm system has bounced around the top three in the MLB for the last few seasons as Roman Anthony, Marcelo Mayer, and Kristian Campbell developed in the minor leagues. Although these three have now graduated out of the prospect tag, Boston still has the 10th best farm system in the league, according to USA Today.
Keith Law, a senior baseball writer for “The Athletic,” revealed his top 100 prospects in baseball on Monday, Jan. 16. The Red Sox have four players on that list, including three pitchers in a bat heavy year.
The four players are SS Franklin Arias (No. 12), LHP Payton Tolle (No. 40), RHP Kyson Witherspoon (No. 62), and LHP Connelly Early (No. 64).
Law only has 26 pitchers in his ranking, meaning Boston’s three is a very positive sign for the future of their rotation.
Tolle and Early Still Listed as Prospects Despite MLB Debuts
We’ve already gotten tastes of Tolle and Early in the big leagues. Both joined the roster in September of the 2025 season; Tolle previewed his electric fastball in three starts, including a phenomenal debut against the Pittsburgh Pirates, who started Paul Skenes on the same day.
Early made a start in the postseason after an injury forced Lucas Giolito out of action. Though he didn’t feature the electricity of Tolle’s fastball, Early was a more polished product, with plus-level offspeed pitches and location.
The combination of Early and Tolle in Boston’s rotation in the future could be an elite 1-2 punch. Early is a crafty, location based pitcher who can out-think his opponents, while Tolle is a power-pitcher who has the ability to hit triple digits throughout a game. That would be a nightmare scenario for a team to see on back to back days.
Both are likely to start the season in AAA after Boston acquired Sonny Gray, Ranger Suárez, and Johan Oviedo to solidify the major league rotation, though Tolle and Early are likely to be the first called up if and when an injury occurs.
Arias and Witherspoon Provide Elite Talent
Arias is one of the most electrifying players in the minor leagues at just 20-years-old. He signed as an international free agent with the Red Sox in 2023, and has already reached AA. In his three professional seasons, he’s hit .299; he projects to be a staple in the Red Sox infield for a long time alongside Marcelo Mayer.
Here’s what Law said about Arias:
“He’s less of a finished product than the other players around him in this range of the list, but if he were a college sophomore right now, we’d be talking about him as a potential 1-1 pick in 2027,” Law wrote.”
Witherspoon was picked No. 15 overall by Boston in the 2025 Draft out of Oklahoma. Although he hasn’t played in the minors yet, his prowess in college has him ranked incredibly high amongst the best pitching prospects in the world.
In two seasons pitching for the Sooners, Witherspoon struck out 210 batters in 171 innings pitched while sporting an ERA of 3.16. If that ERA doesn’t sound amazing, just remember that college players use metal bats; very few pitchers have MLB level stats in college because of this.
The swing and miss stuff is apparent in Witherspoon’s game. His fastball sits at 96 MPH throughout starts, and he already has an MLB level changeup. Law also wrote that he has enough spin to work out a plus-level breaking ball at an MLB level.
