Not sure where you live but you might be able to get White Sox flagship station WMVP AM 1000
Not sure how well Astros flagship station does (KTRH 740)
Here in Houston, I'd prefer to listen to the Stros broadcasters - Milo Hamilton (future HOFer) and Alan Ashby, former Stros catcher - but the radio feed is about 10 seconds ahead of the TV feed. Or the TV is on a 10-second delay. Whatever. But it's very disconcerting to try it that way. Don't know if KTRH even has a live feed, but I'm sure it'd definitely be on an internet delay.
All tied up!
