Just to underscore why I said he was wrong (Because I'm a bitter Braves fan right now, all I have left is to cheer for the Orioles!)
To put Friday's controversial play into context, in the past three seasons, there were six infield flies that were not caught in the majors, according to Baseball Info Solutions, the longest measured at 178 feet.
Friday's infield fly was measured at 225 feet from home plate, according to Baseball Info Solutions.
Not only was it nearly 50 feet further from the longest one called in the last three years, like Grey said, they waited way too long to call it. If they had called it early we might have disagreed with it, but we'd have much less to complain about.
The way he called it, it looks like he waited until he realized Lozmo wasn't going to catch it and then called infield fly. I realize that's probably not what he meant to do, but he didn't call it until everyone knew it was dropping and that completely defeats the purpose of the rule itself which is to alert base runners that they are safe.
