If F1 is slow coming out to take warm-up pitches after being a base runner, what is the umpire's ruling?

The ruling states that F1, the pitcher, cannot take warm-up pitches if they are slow in returning to the pitching mound after being a base runner. This is based on the rule that allows pitchers to take a limited number of warm-up pitches in a given situation, typically when there is a substitution or a change in position. When a player is delayed, the game should proceed in a timely manner to maintain the flow of play, and allowing the pitcher to take warm-up pitches under those circumstances would disrupt that flow.

The rule emphasizes the need for efficiency in the game, particularly during moments that require a quick return to play, such as when a pitcher is coming back from base running. Since warm-up pitches are typically intended for situations where a pitcher has been sitting for an extended period or has just entered the game, there is no provision for taking additional warm-up pitches when the delay is due to the player's own actions as a base runner.
