SimLeague Baseball™ is a baseball simulation game that puts you in the dual role of GM and manager.

Build a team of stars from throughout MLB history. Mantle, Cobb & Manny playing in the same Coors Field outfield? Koufax, Feller & Lincecum in the same rotation in Petco? You can do it all.

Who bats where? What's the bullpen look like? How many pitches should my setup man throw? Who should pinch-hit late in the game down by 2? A 162-game season presents many decisions, and you get to make them all. Earn your league title and win prizes!

Where will you finish in our fantasy baseball simulation?
