Just missed Top 30: Colton Hock
A 2017 fourth-round pick from Stanford, Hock split his time between the rotation and bullpen in his first full season, posting a 4.45 ERA with 77 strikeouts in 91 innings in Class A. He's probably better suited for relief, a role in which his fastball can range from 92-95 mph with heavy sink and his curveball will be sharper in shorter stints.

On the shelf
No. 27 on MLB Pipeline Top 100 Prospects list and the prize of the J.T. Realmuto trade, right-hander Sixto Sanchez missed the second half of 2018 with elbow inflammation and bowed out of an Arizona Fall League assignment with a sore collarbone. He's healthy but the Marlins are bringing him back slowly, so he'll spend some time in extended spring training before a likely assignment to Double-A Jacksonville in the near future. Shortstop Osiris Johnson, a second-round pick last June, will miss all of 2019 after surgery to repair a tibial stress fracture in his right leg in late March. Righty Riley Ferrell, a Rule 5 Draft choice from the Astros, is on Miami's injured list with biceps tendinitis.

Impact prospect: Victor Victor Mesa
Perhaps it’s unfair to put a guy who has yet to play a professional inning on a list like this, but the Marlins didn’t give Mesa $5.25 million to sit in the Minors. He’s 22 and might not need much time before he’s ready, with the ability to make consistent contact, run and really defend. He’d bring some energy to Miami once he gets there.

Breakout prospect: Braxton Garrett
The No. 7 overall pick in the 2016 Draft, Garrett looked like he'd advance rapidly for a high school pitcher -- until he needed Tommy John surgery following his fourth pro start. After missing all of 2018, he's back with his trademark curveball and low-90s fastball.

Best defensive prospect: Jose Devers
The cousin of Red Sox third basemen Rafael Devers, Jose was acquired by the Marlins last offseason in the blockbuster trade that sent Giancarlo Stanton to the Bronx. While he doesn't have his cousin's offensive profile, Devers is a far superior defender, with the soft hands, slick footwork and strong arm needed to be a big league shortstop. He showcased his defensive prowess last season, committing only seven errors and posting a .971 fielding percentage as an 18-year-old in full-season ball.
