They haven't really said. I think it's gonna be a pretty equal split between them until one separates themselves. Ballesteros probably catches once a week.
My thought is Alcantara would be on the team, but they don't want him to rot on the bench and kill any remaining trade value he has. If he rakes in Iowa and they don't need to call him up, maybe he can still net something at the deadline.
I don't think Conforto is totally cooked. One of his last ST games he hit a ball 114, there might be a little left in the tank. Certainly enough to be a 4th/5th OF.
FanGraphs standing projections came out. Cubs are at 84 wins, winning the division over the Pirates by one game.
Nobody but the Dodgers winning more than 87.
