- The White Sox have signed second-rounder Matthew Thompson for $2.1 million, Jonathan Mayo of MLB.com tweets. Thompson’s pick, No. 45, came with a recommended slot value of $1,650,200. The 18-year-old Thompson’s a high school right-hander from Texas whom Mayo and colleague Jim Callis ranked as the 69th-best player entering the draft. Thompson, who had committed to Texas A&M, possesses “an ultra-quick arm and an athletic delivery” that could help him turn into a No. 3 starter in the majors, Mayo and Callis write. He’s the first of the three top 100 White Sox picks from this year’s class to sign. They still have to lock up first baseman Andrew Vaughn (No. 3 overall) and righty Andrew Dalquist (No. 81).
