MLB teams directory: 30 fan game logs

Browse all 30 MLB teams by division, first year of play, and current home park. Open a Gamebook fan log for attended games, scores, seats, and players.

Gamebook’s MLB teams directory lists all 30 current MLB teams by division. Each team page is a personal fan log for games attended, with scores, ballparks, seats, players, and home runs witnessed—not an official schedule or live scoreboard.

Team and first-year facts come from Gamebook's reviewed 2026 MLB registry and the official MLB team directory.

How many MLB teams are there?

MLB has 30 teams split between the American League and National League. Each league has East, Central, and West divisions with five teams apiece.

Can I track every MLB team I have watched?

Yes. Each Gamebook entry counts the home and away teams you watched, then builds your record for that team with scores, ballparks, seats, players, and home runs witnessed.
