Boston Red Sox
They were on WLVI/56 for one year in the late 90s in-between WABU and WFXT. I think it was called something to the effect of The New England Television Network or somethign weird like that. (Not sure of the exact name. Not my team).
And even tho I'm not a fan of the team, I think it sucks you can't watch the games on Free Over The Air TV, except for the handful of games on the FOX Network.
