pitchers footwork

[bluehair]

To keep from turning their shoulder to check on R1 in the set position, some RHP open up their set position (free foot) to the 1B side of the rubber. This is legal and uses the same concept as your LHP's free foot.

The rule book uses words to describe what is legal. It would take too many pictures of legal examples to be practical to include. The off to the side verbage for the wind-up distinguishes that position from having the foot on the rubber. You are facing the batter in the wind-up. It's a completely different position.
