Roman Anthony Best prospect in all of baseballKristian Campbell Best prospect in MLBMarcelo Mayer Started off slow, but has been on a hot streak lately. Needs another 2 months until I'd unleash him on MLB. Franklin Arias Struggled last year in Low A. Not struggling this year. Mikey Romero Probably 2B profile with power. Will be an MLB player somewhere. Luis Perales If he comes back healthy, he has some of the best stuff we've seen in this system.Richard Fitts Starter's frame, plus MLB production and proximity to helping 26 man pushes him up my rankingsHunter Dobbins Proximity to helping 26 man and how he handled brief MLB stints pushes him up my rankingsJuan Valera Best stuff in the system currently, but far away.Connelly Early Pitcher that does a lot of things well and should keep climbing the ladder after adding velo. Will be an MLB starter somewhere.Jhostynxon Garcia Another guy who just keeps producing as he moves up the system. Will be in WOO this year. David Sandlin Nasty stuff, but seems reliever-ish to me due to command profile. Yoeilin Cespedes Doesn't have a good defensive home. Missed a lot of time last year. Yophery Rodriguez Athletic OFer who will get to AA this year. Not an ideal swing for Fenway.Justin Gonzales Will appear in FCL when that season starts late Spring early Summer.Jedixson Paez Lots of concerns about this guy's lack of velo, but he just keeps going out there and pitching well. Throws a lot of strikes so he should keep moving up the system.Brandon Clarke Generated a lot of buzz in ST. He's dominated Low A so far. Probably should head to High A with other college arms. Carlos Narvaez Defensive first profile, but has the ability to split time 50/50 in MLB. Great framing and blocking.Payton Tolle Starter's frame. Sox love his FB. Needs to work on his secondary stuff. Dorian Soto 1.4M IFA this year. All around athletic player currently signed for SS. Advanced raw power for his age. Switch hitter. The skill set that will have him pop up rankings this year and next.
