Groome was selected out of Barnegat Township (N.J.) with the 12th overall pick in the 2016 draft. Some evaluators felt the left-hander was the top talent in the draft, but questions about his makeup cropped up during his senior year of high school, precipitating a draft-day slide. The Red Sox were happy to land the 6-foot-6, 220-pound Groome, whose easy delivery and preternatural curve give him a good base from which to build something special -- a potential No. 2 starter with the stuff to overshoot that projection. The fastball sits in the 93-95 mph range, topping out at 97, and could achieve greater velocity as he adds weight. At 18 years old, he already owns of one of the best curveballs in the minors, and along with his fastball he could bring two 70-grade pitches to the table as he moves up the ladder. He will work on refining his third pitch (a changeup) in the coming season. His command, which wavered during his outings in the Gulf Coast League and the one appearance at short-season Lowell, will also need to improve.
