With the bases loaded, the pitcher is in wind-up position. The pitcher starts his wind-up, but then throws to 3rd base and retires the runner at third base. The plate umpire calls a balk, but the defensive coach insists that this is a legal pick-off move that has been successfully used all season. He insists that everyone has seen a pitcher throw to a base without disengaging from the rubber. He said that he saw this move on TV. Sounds convincing!
