A big, physical lefthander with tantalizing upside as a high schooler in the 2016 draft class, Stinson has steadily climbed closer and closer to his ceiling during his collegiate career. The 6-foot-5, 250-pound southpaw significantly lowered his walk rate from his freshman to sophomore season and also impressed scouts as the top arm on USA Baseball’s Collegiate National Team this summer. Armed with a plus fastball and slider—which some scouts label a grade higher at plus-plus—Stinson has the potential to be an innings-eating workhorse in the starting rotation. However, he’ll need to establish a track record of success as a starter next spring to convince scouts, as he’s pitched more frequently out of the bullpen to this point, and teams wonder about his athleticism and ability to repeat his delivery. He’s got some of the best stuff in the class and is trending in the right direction, but will need to put it all together during his junior season.
