5.1 Starting the Game (OBR Rule 5.01)
Why People Get This Wrong
People often assume that a pitch is only considered delivered when the ball leaves the pitcher's hand, so they argue about pitches where the ball appears to be released but doesn't actually cross home plate. Actually, according to Rule 5.07(b), as long as the pitcher’s arm passes their hip in the forward swing, it counts as a delivery - even if the ball hasn’t fully left the pitcher's hand yet.
Official Verdict
Per OBR Rule 5.01, the home team takes the field and the visiting team sends its first batter to the plate to start the game. Before the game starts, the umpire-in-chief calls "Play" to begin.
