On Friday, Miguel Montero‘s inclusion on the Cubs’ NLCS roster looked shaky at best.

On Saturday, well, any trace of back pain appeared to vanish with the third pitch out of Joe Blanton‘s glove.

Tied 3-3 in the eighth, with the bases loaded and two outs, Montero squared up Blanton’s slider and lifted it deep to right field for the first go-ahead, pinch-hit grand slam in postseason history.

There have been many awe-inspiring moments of the 2016 postseason so far, but this one takes the cake.
