Sixto Sanchez

An underwhelming finish to his rookie season allows for Sanchez to be drafted as an SP3, rather than as an SP2. Even when he scuffled down the stretch, Sanchez's fastball velocity was constant, his command and control were just off. Throwing strikes was not an issue as he cruised through the minors, bypassing Triple-A altogether, so it seems illogical to expect the bad version of Sanchez in 2021. Worth noting: he dominated the Braves in his first matchup, and was chased early the next two times they saw him. While capable of double-digit strikeout games, Sanchez is more focused on inducing weak contact (58.0 GB%) than missing bats. He has three 70-grade pitches in his 97 mph sinker, 99 mph four-seamer and 89 mph changeup, while also mixing in a power slider and mid-80s curveball. His age (22) and velocity elevate his risk of injury, and he probably won't throw more than 160 innings in his first full season.

The most important aspects of Sanchez's season were that he threw a career-high 114 innings and finished the season healthy. Miami held him back to start the year (May 3 debut) to allow him to finish strong after throwing 46.2 innings in 2018 due to elbow inflammation. The plan worked, as the 6-foot righty had a 0.95 ERA, 0.74 WHIP and 39:7 K:BB in 47.1 IP over his final eight starts. He has a pair of 70-grade pitches in his upper-90s fastball and upper-80s changeup. His slider is coming along as a solid third pitch. He also has plus command, which is very rare for a 21-year-old who touches triple-digits. Sanchez is more pitcher than thrower, and his strikeout rate could improve as he hones his craft. He is high-risk from a health standpoint, simply because he is a short pitcher who throws really hard. Sanchez will open the year at Triple-A, but could join the big-league rotation in short order.

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.

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.
