How to get into (Mariners) baseball?

This might be my most asinine post yet, but I swear I’m being genuine.

I’m a man in my 30s and have never had an inkling of interest in any sport, total dweeb status, but I’ve been considering getting into Mariners baseball. I watched the playoffs last year and had fun “rooting for my team,” a new feeling for me. I know the rules of baseball but wonder how to “get into it?”

I should probably watch games, right. But then, how to learn about the current roster? The important stats? Any podcasts? Trying to understand the larger MLB ecosystem scares me at this stage, but if you know of accessible resources in that way, I’m not strictly opposed.

I’ve heard of people listening to games on the radio and hand tallying points etc. Is that fun or worthwhile, or maybe simply what some old-timers like to do?

I realize how silly this sounds, but just looking at ESPN etc., the bulk of information mostly washes over me. I can’t tell what’s important or of historical importance. And I know it’s not an intellectual exercise per se. But maybe this could be a new fun personality trait for me. Anyway thanks
