Someone plz teach me what to do to watch games without cable

I’m not great with tech & streaming, all I want to do is watch the Astros and I don’t wanna pay $100+ a month to do that. Can someone plz give me a rundown of what I need to do 😭. I tried doing the fubo trials but ran out of emails and it’s really not sustainable for me to do that every week. Any help/suggestions are appreciated 🥲
