Thanks for this list, Ct Yankee

I usually use XM Satellite Radio to listen to MLB games while in the car, and most of their audio seems to be relays of local AM stations that are carrying the game in question (for example, last night's game was a relay of WTMJ 620 kHz, a class B station doing 10,000 watts nighttime power) but its nice to have a "real" radio station to listen to in addition to the line of sight satellite signals.
Tried listening to the Cubs/Brewers game late last night [2200-0300 local time, east coast USA] on WSCR 670 kHz AM...this is on a Chevrolet car radio. Unfortunately I heard nothing but a heterodyne. WFAN on 660 kHz was, of course, coming in loud and clear. I generally don't have trouble receiving NYC clear channel AM stations (660, 770, 880, etc) but for whatever reason Chicago wasn't coming in.
WLW was basically nil as well, and its usually similar signal strength to WFAN, WCBS, etc.
