Rex Barney was the PA announcer for the Baltimore Orioles from 1974 until his death in 1997. He was famous for often using the phrase "Give that fan a contract!" when a fan snared a foul ball on the fly. However, if the fan misplayed the ball, Barney would intone, "Give that fan... an error!" This was an expansion on the old radio and TV announcers' comment, "Sign him up!" He would also announce after every game, "Thank youuuuu."

Barney was also a pitcher for the Brooklyn Dodgers in 1943 and from 1946-1950. In 1948, he had his greatest season; he won 15 games and finished second in the National League with 138 strikeouts. The highlight was hurling a no-hitter against the New York Giants on September 9. He had to sit through a one-hour rain delay and showers in the 7th, 8th, and 9th innings to finish the game.
