KYW had the Phillies one year and WOGL has carried the World Series. Not a good fit on 1060, as the "Traffic and Transit on the 2's" gets messed up and that ticks off a lot of people. It was also tried in D.C. on WTOP (carried the O's) and the listeners were not happy.
Sports at night on 98.1 might be allowable with the listeners, but I would not mess up the daytime or weekends. That would really irritate the core audience.
