I never had any opinion on it until Galaragga's perfect game (yes, it was a perfect game, despite the umpire), when by the 7th inning the radio announcers began pointing out that not only were there no hits, no runs, no baserunners, no walks, no errors, but it was a PERFECT GAME! I thought that they shouldn't be saying it. Just mention the usual box score-type updates and be done with it until it's official.
