21-Year-Old PitcherRP

2019 Fantasy Outlook
The top two predictors for Tommy John surgery: throwing really hard and recent elbow trouble. Unfortunately Sanchez gets a big checkmark in both boxes. He was touching 101 mph early in 2018 and hit the disabled list at High-A with elbow inflammation in early June. Sanchez resumed throwing in August, but never returned to game action and was scratched from the Arizona Fall League with right collarbone soreness. While his strikeout rates are not otherworldly, he looks the part of a future big-league ace when he is at his best, showing a potentially 70-grade changeup and plus breaking ball to go with that 80-grade fastball. One realistic scenario: he reports to camp 100% healthy, dominates Double-A and Triple-A hitters, and is the Phillies' No. 2 starter in 2020. Another realistic scenario: he misses a good chunk of 2019 with more elbow issues, gets Tommy John surgery in the fall and misses all of 2020, reporting to Double-A to start the 2021 season.

Dominating at Double-A
PMiami Marlins  AA
July 30, 2019
Sanchez gave up two hits and a walk over six scoreless innings for Double-A Jacksonville on Monday. He struck out five.
The right-hander has won four straight starts, posting a 1.03 ERA, 0.61 WHIP and 25:3 K:BB through 26.1 innings over that stretch. In fact, Sanchez has allowed more than three runs in a start only once since his mid-May promotion to the Southern League, compiling a 2.96 ERA, 1.06 WHIP and 83:15 K:BB over 14 outings and 82 innings. The Marlins' No. 5 fantasy prospect still needs to prove he can handle a regular turn in the rotation, but he's putting himself in position for a 2020 big-league debut.

Past Fantasy Outlooks
With a fastball that can touch 100 mph and the coolest name in the minor leagues, Sanchez has blown up as a coveted asset in dynasty leagues. In addition to his monster fastball, Sanchez throws far more strikes than the typical teenage fireballer. Those are easily his two most impressive traits. His changeup could wind up being a high-end second pitch, but it still needs refining, and his slider and curveball also flash above-average potential. A lot of the same stuff was said about Michael Kopech in past years, and now he is widely considered the game's best pitching prospect, but that's not to say there isn't significant risk in investing in a high-velocity teenager with developing secondaries. His height (six feet) also stands out as a risk factor, as shorter pitchers typically struggle to get downward plane on their fastball. However, he has given up just two home runs in 174.2 innings. Sanchez should head back to High-A to begin 2018, and he appears to be on track for an MLB debut in 2019.
Sanchez, who was signed out of the Dominican Republic in 2015, made his stateside debut last year as a 17-year-old in the Gulf Coast League. He was impressive in 11 starts, going 5-0 with a 0.50 ERA and a 44:8 K:BB in 54 innings. Sanchez is just six feet tall, but he has a mid-90s fastball with movement that tops out at 99 mph. He has shown good command of that pitch for someone of his age and experience. Sanchez also boasts a curveball and changeup that each have a chance to be plus offerings in time. While he is shorter than most starting pitching prospects, Sanchez is a sturdy 200 pounds, and has a starter's repertoire and command. Dynasty league owners will only hold a pitcher's size against him for so long, so this is a good time to buy. He is expected to open the season at Low-A Lakewood, and if he starts missing more bats with his secondaries, he will go from trendy sleeper to top-100 prospect in a hurry.
