Here are the Marlins' 2019 Top 30 Prospects

February 19th, 2019

There's no question that the Marlins' farm system has improved since Bruce Sherman and Derek Jeter purchased the franchise from Jeffrey Loria in September 2017. Whether it's strong enough to eventually return the big league club to contention remains very much in question, however.

Undergoing yet another rebuild, Miami has traded , , , and in the last 14 months, turning its five best players when Jeter assumed control of baseball operations into big leaguers and plus 15 prospects, 12 of whom are on our latest Marlins Top 30 list. The best of them is right-hander Sixto Sanchez, who has drawn comparisons to Pedro Martinez but also missed most of 2018 with elbow inflammation -- and he's still the safest bet among the many high-risk/high-reward types Miami has collected.

Outfielders (since graduated to the big leagues) and have yet to prove they can make enough contact to deliver on their five-tool promise, while right-handers and Jorge Guzman still must demonstrate that they can harness their overpowering stuff. Cuban outfielder Victor Victor Mesa signed in October for $5.25 million, a franchise record for a position player, yet generates mixed reviews about his offensive upside.

Here's a look at the Marlins' top prospects:

  1. Sixto Sanchez, RHP
  2. Victor Victor Mesa, OF
  3. Monte Harrison, OF
  4. , RHP
  5. Sandy Alcantara, RHP
