19. Arquimedes Caminero, RHP
Age: Height: Weight:
The Marlins have a number of interesting relief prospects, including Grant Dayton, Chris Hatcher, Michael Brady, A.J. Ramos, Scott McGough, and Tom Koehler. All these players are roughly equal caliber prospects, with the potential to become set-up men in the majors. We chose to include Arquimedes Caminero on this list because of his tremendous stuff. He doesn't have the best statistical record of the group, but his potential upside is the highest. The 25-year-old right hander's fastball reaches a high-90s velocity, and can completely shut down batters.
Caminero's greatest drawback is his lack of command. He walked nineteen batters in thirty-eight innings pitched last season, representing only a slight improvement on his career walk rate.
Caminero is currently on the 40-man roster, so there is a reasonable chance he could pitch for the Marlins this season.
20. Alfredo Silverio, OF
Age: Height: Weight:
Alfredo Silverio could prove to be an amazing Rule 5 draft steal for the Miami Marlins, or he could fade from memory, never playing at a professional level again. Silverio was once a highly touted prospect for the Los Angeles Dodgers, ranked fourth in their organization by Baseball America. Then disaster struck. Silverio was involved in a serious automobile accident, which caused him to miss the entire 2012 season. His current health status is unknown, making him a different prospect to rank properly.
When Silverio was healthy, he was a very exciting prospect. He ran well in the outfield, playing a respectable center field, but also spending time in the corner spots. He possessed solid arm strength, making him a good candidate for right field. He generated decent bat speed, hitting line drives, and even a few home runs. He put up a .306/.340/.542 slash line in 572 plate appearances for Double-A Chattanooga in 2011.
Silverio had all the makings of an everyday major league outfielder on a competitive team. Can he bounce back from a serious injury? How much progress has been lost? Is he healthy today? These questions push Silverio down to the bottom of the prospect list, but not entirely out.
Sam, Conor, and I hope you enjoyed this off-season's prospect coverage. We are very excited about the current state of the Marlins farm system. If Jose Fernandez loses his prospect eligibility, the farm will lose its crown jewel, and may suffer in the annual organizational rankings. This loss should be offset by improvements elsewhere. We are optimistic that young players such as Jacob Realmuto, Mason Hope, and Jake Marisnick will take major steps forward this year. Justin Nicolino, Christian Yelich, and Andrew Heaney should also perform well.
We will now begin gearing up for coverage of the upcoming Amateur Draft. Stayed tuned for more content.
