Sanchez was the key prospect piece to this off-season’s J.T. Realmuto deal, the centerpiece of Philadelphia’s package to the Marlins. He’s one of the highest-ceiling arms in the minors and could jump into top-20 overall prospect consideration with a healthy 2019. Sanchez tuned 20 in the middle of last season, dominating older competition in the Advanced A Florida State League until an elbow inflammation shut him down in July. He was going to make up the lost time in Fall League but missed that due to injury as well, a late scratch from Scottsdale’s roster due to neck and collarbone issues.
At his best, Sanchez locates a high-90s heater with heavy run. It’s a blow-by pitch that induces weak ground ball contact. A sharp curve and changeup both are future plus pitches, and a slider gives a fourth look to keep hitters honest. What’s most impressive is his ability limit walks for a power arm, something that leaves little doubt about his ability to remain a starter provided he can handle the workload. The durability concerns that stem from Sanchez’ injury history and shorter frame are the only questions he faces entering 2019. We see his ceiling as a #2/#3 type starter.
