**Of course you can always go to a bar where at least one game will be airing. Likely you will have to ask the bartender to switch to XYZ ESPN affiliate station for a specific game, as they usually don't default to airing the more obscure ESPN channels. But in my experience, that's rarely an issue.
Stream CWS Games
WatchESPN. This service can be streamed to a wide variety of devices, including your smart TV, gaming console, smart phone or PC/Macbook. All you will need is cable login credentials (or a close friends or family members could also do the trick here). Going to that link will provide the entire schedule of events, and you can filter College Baseball World Series info on the main page as well.
Games stream in real time, live. There is post commentary, highlights and more. All ESPN channels are available through this app, including ESPNEWS.
Conference Specific Options
SEC Network partners with ESPN and the Watch ESPN app. (It's owned by ESPN really) So if you're interested in any SEC baseball World Series games, you can stream the SEC Network directly. Or you can watch their games on the SEC Network cable channel as well.
