Kuiper's broadcasting career began while still a player, hosting his own KNBR radio show from 1982 to 1985.After retiring from playing baseball, Kuiper provided commentary for the Giants from 1986 to 1992. With uncertainty over whether the Giants would move to Florida for the 1993 season, Kuiper left for a one-year stint with the expansion Colorado Rockies in 1993.Kuiper returned to broadcast for the Giants in 1994, where he has remained since.
在同一场比赛中，库伊珀还称在第七局上场，在布兰柯made a diving catch in right field to preserve the perfect game:
And this is hit out into the alleyway, a long run for Blanco, and Blanco's gonna dive, and HE MAKES THE CATCH!
While principally a television play-by-play announcer onNBC Sports Bay Area, Kuiper also shares radio play-by-play duties with Dave Flemming on KNBR when the Giants television broadcast is carried over-the-air onKNTVand Jon Miller handles the television play-by-play. He also fills in on the radio side when Flemming is unable to announce games due to his second job as an ESPN college football and basketball announcer. During Giants post-season play, Kuiper and broadcast partner迈克·克鲁科move over to the radio side and call games with Miller and Flemming while the television broadcasts are handled by network sportscasters.
Kuiper uses a deep voice when a player swings and misses, when a dramatic play is made, and when he calls home runs.
Kuiper is noted for his distinctive calls beginning and ending each game: after the result of the first batter of the game, he says, "And that's how this game gets started"; when the ball game is over, Kuiper says, "And that's the ball game!"
When Kuiper states the pitch count on a batter, he often calls "nothing" in lieu of calling "a ball" and the current number of strikes when the count is "no balls". Kuiper often uses the phrase "Got 'em!" 当一个记录。
