I imagine maybe the sports anchor operates in a dual role these days. "And that's today's sports wrap-up....now if you'll excuse me I have to go mop the break room. On to Sandy and today's weather."
I am not sure what local radio station serves my area: there seems to be two or three that overlap a bit! So I don't know what sports news they carry, if any. If anything like the major TV channels and the Radio Times listing for BBC Radio Five, "sports" are very limited in scope, predominantly all-professional football, cricket, boxing and tennis.
Most local stations I have encountered, especially the commercial ones, are merely pop-music broadcasters made centrally and flavoured with local advertisements and news headlines.
However, our local newspaper does cover local sports quite well, from the semi-pro football and County cricket teams, via dinghy sailing and windsurfing contests, to the local skittles leagues.
