2017 Fantasy Outlook
Tommy John surgery in his junior year of high school dropped Thompson to the third round of the 2016 first-year player draft, when the Padres took a gamble on the 19-year-old and swayed him from a Texas commitment with $1.75 million. Thompson has some work to do to fill out his 6-foot-7, 186-pound frame, but he has the stuff to succeed if he can do so. He posts good velocity and has some decent backup pitches, which he showed off in 12 innings for the Padres' rookie league team in the Arizona League. Thompson struck out 12 batters in his five starts, allowing just eight hits en route to a 2.25 ERA and 1.08 WHIP. He'll begin next season in a low minor league level, but the Padres will have high hopes for his success if he can stay healthy and begin to add more strength.
