Holliday pulled up short and Kozma stepped away.
There is no "short outfield" rule, there is no "chance to play the ball" rule. The rule is "ordinary effort".
Again, if any infielder has a shot at playing the ball, the infield fly rule can apply, if all other criteria are met.
Kozma had to run out about 50 feet into the outfield. This was not an ordinary effort for an infielder.
Really? Better tell all those infielders to stop running into the outfield to make a play then, since that's supposedly beyond ordinary effort for them. Trust me, ITL, you know as well as I do there is at least one play a game an infielder makes in the outfield, and as long as the infielder can make a play, the infield fly rule can be called.
Also, watch at about the 2:50 mark of the video.
The left field umpire doesn't call infield fly until the ball is about to hit the ground.
So? He can call it at any time, and you don't know if he shouted out the call before the sign or not. That, too, happens all the time.
Example: I played in the old Big Eight. At Oklahoma, I attempted to steal third, and heard the umpire call "Safe!" But when I got up to take the bag and dust myself off, he said, "Get outta here, Short! You're out." I protested, telling him I heard him say "Safe!" He said, "Yeah, but I used my hand to tell 2,500 people you're out, so git!"
