The rule is invoked when an infielder can make the play. Kozma had no trouble getting under the ball. Or, oddly enough, then getting out from under it. It's a major leaguer making a major league play. It's a more obvious call when the ball drops between third base and the mound. It's still an infield fly if the infielder can make the play in the outfield. Everytime the ump makes that call, with the infielder camped under the ball in the outfield, a bunch of people get their panties in a bunch. It was true coaching youth baseball for 10 years and it's fun seeing it in the majors.
Now about that blown call at first....
HONK!
