Honestly, a lot of outfielders are not consistent with their throws. Part of it is the fact that they have to really throw hard only a few times a games. That's leads to a lot of inconsistency with some guys from the strength of their throws to accuracy issues. You very well may have seen solid average throws from Mountcastle and Stewart. I know I have at times too, but I can't overlook some of the really poor throws too.
I would be surprised if we get an answer to that question this year.
He is definitely one of the players, along with DJ Stewart, I most wanted a full season of data on at the MLB level this year and unfortunately we aren't going to get it.
Well, at the moment I don’t think we have anyone who is better, and damn few who are as good. I am happy giving him playing time until someone better comes along, and the better he gets, the better the new guy will have to get.
If Santander plays left and Stewart plays right Mountcastle will never play the outfield. Mountcastle's arm is not good enough to play right and he is not good enough to move Santander out of left.
So Mountcastle better hope that Stewart is starting the season in left field.
