Ballesteros is for sure a hinge prospect.
1. Gomes will be 36.
2. Amaya is a nice kid, and after having missed most of the previous 3 seasons his readiness was a fun surprise. But assuming Amaya as a primary catcher down the road is a possible hope, but no certainty. His soft qualities are good, but hitting and throwing are part of baseball too. Young players can get better, so who knows. But it's possible that he'll be pretty bad offensively, and will be even worse in managing the stolen-base game. I hope he grows into it, but assuming Amaya as the primary catcher for a string of contending seasons is shaky.
Ballesteros, who knows. Haven't gotten any great defensive reports on him. And it's not like he was a big power guy this year. 2/3 of his hits were singles. (120 hits, 79 singles, 14 HR, 27 doubles). Hard to know how he projects.
1. Power, for example, a lot of teenagers mature physically and grow into more power. A lot of heavy teenage athletes go to college football, and get way more sculpted by age 21 or 22. Maybe Ballesteros at 22 will be a physical specimen, and he'll hit with more XBH/HR power down the road? Or maybe not, maybe he's already full-grown and 14-HR is kinda the HR-level that we should project? Who knows?
2. Catching: A lot of big-league catchers weren't big-league ready as teenagers. Maybe his receiving and throwing will be just fine with work, in terms of the physical stuff?
3. Soft stuff: Who knows, maybe he's the smartest student of the game, and will be a good pitcher-whisperer, and he'll have all the soft-stuff that Gomes has? Who knows?
But yeah, *IF* between Amaya and Ballasteros the Cubs had two good home-grown catchers for years, and *if* Ballesteros could hypothetically become a solid defensive guy and a good offensive guy, that can change the trajectory of a franchise.
