How to watch games on tv without all the shenanigans

I have only internet service at my house. No antenna, no dish. I’d like to watch Astros games, both home and away, hassle-free.

Currently, I have been streaming games from various sketchy sites. I have gotten frustrated with this process and do not want to do this anymore.

My desire is to get a quality feed of all games, somehow. I don’t mind paying to do this.

Is there anyway possible for me to get all games on my tv via the internet without illegal streaming?
