He was already in AAA long enough that 2019 will not count as a full season of MLB service time. The only uncertainty is if he will qualify for Super Two which would mean four trips through Arbys instead of the standard three. I don't believe we will officially know that until the end of the season though. Just extend him. I don't know if he will ever be a great defensive 2b. I don't know if the power will be there to be a superstar. What should be pretty clear is this kids hit tool is pretty impressive and he should be an obp monster. That .408 in SA doesn't look like a fluke and its not that he got on 3 times tonight. It's the ease at which he makes hard contact with the ball and that he is shift proof. If he has power at the MLB level he's a 3 hitter, if not he could be a lead off guy. Just tonight... up the middle, BB, down the RF line, and into LF. I mean... come on.
