Garrett, who the Marlins selected with the No. 7 pick in the 2016 draft, only logged 15.1 innings in 2017 before eventually needing Tommy John surgery in late June. This, after he didn't pitch at all the year he was drafted as the Marlins attempted to exercise caution with his workload. Even though Garrett won't return to game action until July or August of this year, at the earliest, he is still one of the top prospects in a system that was essentially bare before this offseason's rebuild. A lefty with the potential for a plus fastball, plus curveball and above-average command, Garrett could top out as a No. 2 starter if his recovery goes perfectly and his changeup develops. The more likely outcome is that he develops into a No. 3 or No. 4 starter. Given how much his development is delayed, Garrett is unlikely to reach the majors until 2021 or 2022.

Garrett might be the safest of the high school arms from the 2016 draft class, which is an odd statement considering he is the only pitcher who was selected in the first 30 picks who has not yet pitched in a game. The Marlins opted to let Garrett take his time in his recovery from Tommy John surgery rather than rush him to an affiliate. He fell to the Marlins with the seventh pick, but his $4.15 million bonus ranks third in the class, reflecting his pre-draft pedigree. Unfortunately that pedigree does not quite translate over to fantasy. Garrett, a 6-foot-3, 190-pound southpaw, should be owned in leagues that roster 125-plus prospects, but he lacks frontline upside. A low-90s fastball and plus curveball lead a three-pitch mix, and if everything goes well, he will develop into a No. 3 starter. Jason Groome, Forrest Whitley, Riley Pint and Matt Manning are preferable investments among the prep arms from his draft class.
