I’m going to cheat a little here; my phrase is not from a sportscaster but a manager.
1984 World Series, Padres vs. Tigers, Game 5. Tigers are up 5-4 in the eighth inning. Kirk Gibson is up with one out, runners on second and third. Everybody watching assumes Goose Gossage will issue an intentional pass to set up the double play. Gossage’s manager, Dick Williams, gives the IP sign, Gossage disagrees. Williams goes to the mound and Gossage convinces him to let him pitch to Gibson.
Not a one-time phrase, but a signature one: “He shoots! He scores!”
Foster Hewitt, who was the leading play-by-play announcer for hockey on radio and then tv in Canada for forty years, used the phrase throughout that forty year period.
