The most annoying thing is, "Theeeeeee Yankeessss Winnnnnnnnnnn!!!" Not because it is the Yankees, it is because it just sounds horrible.https://soundcloud.com/notindabuilding/john-sterlings-gaffe-in-alex
It amazes me that a franchise like the Yankees employ such a clown to do the radio broadcasts. His girlfriend Waldmyn is just as bad.
A lot of teams have lame announcers. The Dodgers have Steiner who can be over dramatic at times. The White Sox have the biggest homer around, Harrelson. The Red Sox have an announcer, Orsillo, that sounds like he is always announcing a golf match that puts people to sleep.
The best current announcing team IMO, believe it or not, are the Giants Krukow and Kuiper. This is coming from a Dodgers fan who does not like the Giants.
