All the viewing options you could ever need to watch any College Baseball World Series game are included in this entry: TV viewing options and the full NCAA schedule, online streaming options for all kinds of devices, as well as any conference specific viewing.
TV Viewing Options
ESPN will be exclusively airing every Division 1 Men's baseball World Series game on one of their many ESPN channels, including ESPN, EPSN2, ESPN3, and ESPNU.
Here is the full NCAA TV Broadcast Schedule. Use the filters to narrow your search down by network, schedule type, division, month, sport or even year. (I have already preselected everything for you, just a heads up that it's totally customizable).
You will need a cable subscription to watch in the comfort of your home, on your own TV. Of course you can always go to a bar and odds are 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.
Now if you are looking to stream the games instead....
Online Viewing Options
IF You Have Cable Service -
Watch ESPN app. 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.
Games stream in real time, live. Also there is post commentary, highlights and more. All ESPN channels are available through this app, including ESPNEWS.
IF You Don't Have Cable Service -
If not, consider Sling TV. It runs for $20/month. And they give you a 7-day free trial, so you can try out the service and make sure it's worth it to you. Sling TV also gives you ESPN, a handle of cable channels as well, 23 channels in total.
This will stream to any smart phone or PC/MAC, as well as a plethora of streaming devices:
Amazon FireTV, ROKU, Chromecast, XBOX, AndriodTV, and more.
And finally there are a few more options still out there..
Conference Specific Options
SEC Network partners with ESPN and the Watch ESPN app. (It's owned by ESPN really) So if you are interested in any SEC baseball World Series games, you can stream the SEC Network affiliate station directly.
Or you can watch their games on the SEC Network cable channel as well. Make sure and ask your cable provider which station that will be; likely there will be a slight charge to add the service if you aren't already getting it.
