The OKC announcer described the oppo blast Happ hit last night as hitting the brick wall behind and to the left of the LED video board in that picture. It was easy oppo power too. When I watched it, it looked like a fairly easy fly out. Wind was blowing out pretty strong though. Wind was out today too, but the crack off the bat was "The Sound of HRs" no doubt power.
Are you sure this wasn't from Friday's game? That's exactly where Happ put Friday's HR. As far as OKC's park being a hitter's park, just check the dimensions on that porch.
I'm creating the ridiculous "Candelario > Bryant" club right now. Jeimer was easily the best player of the field and needs to be return some powerful MLBer that gets us another World Series victory. The arm, defense, bat, it was all there tonight.
