Thompson, 22, was acquired from the Rangers along with five other players in the Cole Hamels trade last summer. MLB Pipeline ranked him as the Phillies’ fifth-best prospect. According to the scout reports, Thompson possesses four pitches that figure to be average or better in the big leagues: a fastball that can hit the mid-90’s, as well as a slider, a curve, and a change-up.
In 129 2/3 innings with Triple-A Lehigh Valley, Thompson has put up a 2.50 ERA with an 87/37 K/BB ratio in 129 2/3 innings. He has been particularly dominant since the beginning of June, posting a 1.21 ERA and a 42/18 K/BB ratio in 74 1/3 innings across his last 11 starts.
