What can the pitcher do while in the wind-up position?

When the pitcher is in the wind-up position, they have the flexibility to either deliver a pitch or step backward off the pitcher's plate. This aspect of the wind-up allows the pitcher to maintain balance and control, enabling them to make adjustments as needed before committing to the pitch.

Stepping backward off the plate can serve a strategic purpose, such as gaining a better angle or preparing for a pick-off throw. Additionally, this movement does not violate the rules governing the pitcher's actions, which permits the pitcher some leeway in how they initiate their throwing motion.

The ability to pause and reassess is generally linked with the set position rather than the wind-up, where the pitcher is expected to make their delivery. Therefore, the options that restrict the pitcher's actions while in the wind-up do not align with the rules and the game's strategic elements.
