It's far too small of a sample to have significance yet or warrant strong emotions about, but poking around earlier this morning I started looking some more at Jesus Montero and specifically his hitting numbers.
sOPS+ is OPS+ relative to the position.
It's probably just a fluke. I think it's going to end up being just a fluke. But feel free to add this to your list of reasons to hope Jesus Montero continues to get starts at catcher after Miguel Olivo comes back.
