Hernandez is NOT a decent 2B. We can say SSS, but in the SSS we have to go on, he's a poor fielder.
It makes more sense to do it for the winning run rather than the tying run. Even if he's thrown out, it still goes to extras and the Cards had blown through that pen in one inning.
I think the Vlad Dracul will do the following:
2017: stay under LT
2018: go slightly over LT, if they miss playoffs ---->
2019: sign overpriced FA which fail
2020: tear it down and start over with new GM
