10. Washington Nationals
The Nationals saw teenager Juan Soto set the league on fire, but the outfielder who was top-ranked coming into the season was Victor Robles, and after a season marred by injury, Robles could be an impact player in 2019 for the Nationals. Carter Kieboom is a guy that should move into the top 50 in a lot of MLB top prospects lists due to his incredible ability and production this season.
9. Cincinnati Reds
Before he was injured, Hunter Greene had begun to show the ability that led to the Reds trusting him to use his incredible arm off of the mound instead of pursuing his big bat. The hope is that he’ll make his way to the mound in late 2019 and be able to progress again. Nick Senzel seemed on a path to push the Reds for a spot in the big leagues before he was injured as well.
8. Atlanta Braves
With the players like Acuna and Albies making their way to the majors, the Braves are left with two arms at the top of their list, and they could not be more different. Mike Soroka is the epitome of mental approach on the mound, with the ability to manipulate his pitches and dominate a game in that way. Ian Anderson has all the raw stuff, but he needed to harness it, which he really made huge strides in doing in 2018, arguably overtaking Soroka as the top prospect in the system.
7. Los Angeles Angels
Coming into the 2017 draft, many saw Jo Adell as a very talented player who had not faced top competition, and therefore was likely going to take multiple years in the minor leagues. Instead, Adell has launched himself into the top 10 of all prospects with his incredible 2018 season. Not at the same level as Adell, but Brandon Marsh has similarly outleaped expectations this year going from a guy who wasn not on MLB top prospects lists, but he certainly will factor into them this offseason.
6. Tampa Bay Rays
With one of the best farm systems in the game graduating multiple players to the major leagues this year, the Rays also had Wander Franco establish himself among the top 2-3 prospects in all of baseball. Pairing that with the tremendous talent that Brent Honeywell displayed before his Tommy John, and you have a very impressive duo who are on very different ends of the development curve, with Franco likely to open in low-A in 2019 and Honeywell likely to fight for a big league rotation job.
