More an incompetent tradition than a cliche here.
Score updates on radio. The correspondent at a game doesn't state the score at the start of his update, and proceeds to ramble on about what the score was at the time of their last update and things that have happened since the last update, losing the listener's interest and patience in the process. Sometimes the updater never actually gets around to reading out the current score.
This applies to both national and local radio.
