They will absolutely be available to watch, it'll just be a matter of where (stateroom only, pub, Funnel Vision, etc). I was on for the college football national championship for one of the Alabama/Clemson games and it was shown in the pub and on Funnel Vision. I can certainly see this with that game and the Super Bowl but the World Series will be up to seven games. I would like to think they would show it on Funnel Vision but I could easily see that not being the case. But the ultimate answer to your question is yes, you'll be able to see it while on the boat. Just set your expectations to watch it from your room or the pub.
