Prospect Number 10: Joan Gregorio

Gregorio has a whole lot of room to grow. I’m not really sure where he fits in. He’s slowly been knocked down the list of Giants prospects as he struggles to figure things out at the higher levels of the minors. It seemed like he finally had things figured out in double, but didn’t enjoy the type of success at Triple-A last season that would justify him being ranked above some of the other pitchers on the list.

His fastball is absolutely electric, and has a solid slider. What he doesn’t have yet, that usually separates starters from relievers, is a consistently good third pitch. His change-up still needs a lot of work. Unless he bursts onto the scene and is destroying people in Sacramento this season, I don’t think he’ll ever make the Giants starting rotation (barring multiple tragedies).

He could, however, be a fantastic bullpen option at some point. I think that’s his most likely destination, which could bump up his ETA a bit. He could potentially get called-up at the roster expansion date this season, but we’ll see. I’d give him an MLB ETA of 2018. Mainly because this year will sort out whether or not he’s a bullpen guy, or a starter.
