I believe they absolutely made the right call in that situation. Kozma got back there and turn around and called the ball. At that point it became an infield fly. It does not have to be in the infield, the infield fly ruled is used all of the time when the popup is on the outfield grass. I think they made the right call and I think Joe Torre did the right thing by denying the protest immediately before play was resumed. It was a judgement call and that is something that would never be overturned in a protest.
