Maybe. I haven't looked but I'm guessing his low balls in play % this year is slightly out of character and that problem will fix itself with some more at-bats. He missed spring training and a sizeable chunk of the year so far. I'm surprised he is doing as well as he is given his very late start, and I think we all are surprised (thus these conversations).
The likelihood of Sano turning into Logan Morrison anytime soon is pretty low, so I'm not worried about it. He will be fine, especially on this team in this year where everyone is putting in their all. Frankly I'm more concerned with how Sano will do in future years.
There is some deja vu with this conversation, we had these sorts of convos for a long time around Rosario.
The main difference between these conversations and those about Rosario is that there are always people who want to attack Sano's character, and this gives them a forum to do so -- even when he's raking.
