I had a similar fandom journey as you Matt - I came to Vancouver / Rockies / Toronto on honeymoon in '16 and caught a game a Rogers Centre (not my first baseball game mind, that was at Fenway Park…but I didn't fall for Boston the same way I fell for Canada!).
Since then I've been back to Vancouver and caught a Vancouver Canadians game which was cool. I subscribe annually to MLBTV - compared to our sports packages in the UK it really is very reasonable, ~£150 for the entire season including all games, full game replays and highlights packages.
I tend to watch most weekend games as they tend to be 6pm / 8pm in the UK, and there is the occasional midweek "day game" as well, watchable in the UK. For the other games, I watch the full game replays over breakfast and use the 15 second skip to condense the game down to about 45 mins so it becomes a kind of extended highlights.
Podcast wise - I often listen to the Sportsnet podcast, At The Letters and another called Blue Jays Happy Hour. There are a few others; Bat Flips & Maple Dips, Jay Bird Watching…less production value and more like a few mates chatting down the pub which I'll sometimes listen to.
I also played a fair bit of MLB The Show and have read a couple of books. I think one was called Smart Baseball as was about advanced metrics.
Anyway - baseball is a wonderful sport, full of great moments - I just missed out on the Bautista bat flip, but I was up late for the Eddie Encarnacion wild card bomb against the Orioles!
Enjoy!
