John Sterling is An Idiot, Doncha Know

Yankee announcer John Sterling is one of the worst announcers in the history of the world. Because he caters to Yankee fans who love that sort of thing, he creates taglines and obnoxious cheers for each Yankee player. But he gets so involved in his stupid schtick that he doesn't pay attention to the game.

This is just one example, there are countless others, without even mentioning all the times he prematurely went into his "it is high, it is far" gimmick on fly balls that were eventually caught.
