He's one of those uncommon players who has played full-time at each level followed by a promotion each time. And weak second-half or not, his season stats in 2017 were his best yet. The same logic they used in prior years would suggest AAA. What good will another hot start at AA do him, anyway? Observers, both professional and just us fans, would still say, wait, we don't know if he will fade. I would just bump him to Rochester and see how he does. If the questions are more about his glove, he won't learn more in AA than AAA on that aspect of his game. And he's so young, a bad 2018 at AAA still wouldn't mean very much for his long-term chances.
