If a play-by-play announcer is asking the same question so frequently that it becomes a meme or a cliche, something's wrong with the broadcast. If John and Steve and the producer think viewers are intently interested in 3-0 count strategy, then Steve should know to talk about it without being repeatedly prompted. If Steve doesn't jump in on his own and John thinks there's value to the viewers in bringing it up, then the burden is on John to tell us why we should care. (Baseball Reference actually tracks each team's swing percentage on 3-0 counts, so that could be an interesting way into the discussion. And even John saying something like,"Yesterday, Vargas swung at a 3-0 pitch, but that was with a big lead" gives viewers context and tees up Steve to talk about how strategy differs in different situations.) Repetition is inevitable over a 162 game season, but the best announcers are always looking for opportunities to bring new information to the viewers, rather than asking the same question the same way again and again.
