BLUES' MANUAL decodes the rules and real-world calls of baseball for umpires, coaches, and serious fans. Through clear, scenario-driven guidance and practical interpretation tools, we bridge the gap between rulebook text and on-field judgment — Umpires' Interpretation — helping officials make confident, consistent calls while educating teams and fans on why those calls matter.

We believe clarity, consistency, and respect make the game fair. BLUES' MANUAL champions precise rule interpretation delivered with practical empathy: we translate complex regulations into usable judgment, train with real-game scenarios, and foster open dialogue between umpires, players, and fans so every decision is informed, accountable, and rooted in love for the sport.
