About This Game

DIAMOND OFFICE: BASEBALL GM

Games are won on the field, but great teams are built in the front office.

DIAMOND OFFICE: BASEBALL GM is a single-player baseball management simulation that puts you in charge of your own baseball club.

Compete in a fictional professional baseball league featuring 10 teams and lead your club with your own baseball philosophy.

Shape the Future of Your Club

From roster management and trades to free-agent contracts and scouting, every decision you make as general manager influences your team's present and future.

Manage your club's finances, make the most of your available resources, and build a competitive roster.

Sign International Players

Search for international talent that could transform your team.

Sign new players, negotiate contract renewals, or replace those who fail to meet expectations. A single outstanding signing could change your team's fortunes, but not every investment will pay off.

Draft the Next Generation

Discover promising young talent through the rookie draft.

Balance immediate improvements with long-term player development and watch unknown prospects grow into the stars of tomorrow.

Build Your Ideal Lineup

Analyze player abilities and performance statistics to construct your ideal batting lineup and pitching staff.

Will you build a powerful offense or focus on a dominant pitching rotation? The choice is yours.

Experience Baseball Through Simulation

Rather than controlling players directly, follow the action through text-based play-by-play commentary and detailed game statistics.

Watch your strategic decisions unfold on the field.

Explore the History of Your League

From individual player statistics to team performances and season records, explore the history of your league in the record book.

Look back on legendary players, championship teams, and historic achievements as you create your own baseball legacy.

Build a Franchise Across Generations

New prospects emerge, young players develop, veterans decline, and contracts and rosters continually change.

Experience the challenge of long-term team management in a league that evolves season after season.
