If Desmond didn't get pulled for how he played for two plus years, Espinosa won't either.
Needless to say, it's a very nice thing to have Anthony Rendon waiting in the wings and if he proves he can defensively handle 2B, I'd like to see him take over and move Espinosa for something else... like a long term 1B or C.
A good defensive 2B who whiffs a lot doesn't get you the long term answer at 1st, but it should get you a plus lefty reliever.
