Witherspoon

MLB Pipeline’s Jim Callis reports Witherspoon will receive a $5 million signing bonus, which represents a nearly full-slot deal for the 15th overall pick in the 2025 MLB Draft. The 20-year-old righty ships up to Boston following a standout collegiate career at Oklahoma. His combination of athleticism, mid-90’s fastball velocity and improving command give him a shot at reaching his top-of-the-rotation ceiling in a couple years.

Witherspoon was solid in his sophomore season with the Sooners, but took a big step in 2025 as a junior with a 124/23 K/BB ratio over 95 innings and a 2.65 ERA over his 16 starts. The 6-foot-2 right-hander has an athletic delivery that allows him to repeat his actions at a solid rate, and he’s shown four different pitches that grade 60 or better on the 20-80 scouting scale. The command is still very much a work-in-progress, but keep in mind he doesn’t turn 21 until August. Witherspoon offers a little more risk than some of the other upper-echelon college arms, but also a little more upside to go with it. He could be a top-of-the-rotation arm that reaches the majors by 2027.
