Pick 25 real-life MLB players from any season in history — all the way back to 1885.
Stack Babe Ruth with Barry Bonds, pair Pedro Martinez with Shohei Ohtani, or build a
rotation of Maddux, Clemens, and Kershaw. You’ve got the entire history of baseball at
your fingertips — just stay under the salary cap and build your winning formula.
Set your rotation with guys like Sandy Koufax and Justin Verlander. Bat Pete Rose leadoff, throw Big Papi in the cleanup spot, and bring Mariano Rivera out of the bullpen to close it down. You’re in charge of lineups, trades, waivers, call-ups — every roster move is up to you. Think you can do a better job than your favorite team’s GM? Now’s your chance to prove it.
Hop into a 24-team league with divisions, wild cards, and a shot at the World Series. Or try a Theme League with fun twists — like only drafting rookies, Hall of Famers, or players from a certain decade. Our Theme League Wizard makes it easy to join or create something totally unique.
Games run three times a day — morning, afternoon, and evening — and every pitch is powered by real-life MLB stats. Follow the action with full boxscores, play-by-play recaps, and deep stat tracking for every player on your roster.
Make it to the finals in your league and you’ll qualify for our Tournament of Champions — a 32-team showdown with up to $150 in prizes on the line.
Thousands of baseball fans are already building teams, running leagues, and talking
strategy. Whether you’re brand new or a longtime sim vet, you’ll find players ready to help,
compete, and talk baseball 24/7.
