When you're trying to peg a breakout, what you're really looking for are specific and realistic avenues to improve that combine with the skills a guy already has that can help him level up. Chris Morel is a great example. In 2022 his problems were lack of contact, hitting too many balls on the ground, and lack of defensive value despite his athleticism. Last year he started lifting the ball a lot more without giving anything else back, and this year we're hoping he makes defensive strides while keeping his offense (at least) steady.
Amaya I think has an even easier path to being an impact player. Based on what he showed last year, he looks to have all the components of an above average MLB hitter. The plate discipline and contact are a smidge better than average, the raw power is average, the hard hit rate is a little low but he barrels the ball well because he hits so much in the air. On defense he had strong framing grades, but he was a little noodle armed against opposing baserunners. He got good reviews for his soft skills, though generally Ross only paired him with Hendricks or guys Miguel had already worked with in the minors.
So what are his avenues to a breakout? One is for his component offensive skills, which are above average, to begin translating into above average production. That's generally how it works, so likely the fact that it didn't last year is just a SSS thing (particularly when you look at what he did in the minors). The second is to iron out the defense. The arm was supposedly great when he was young, so you can realistically hope a year further out from TJ it can improve. And the last one is to maintain his skills while piling up more playing time. As I laid out above there's a lot to like about the skills he showed last year, but it can be tough to maintain those through the rigors of catching. And that's not even mentioning Amaya's specific injury history.
