The eight warm-up throws for the starting pitcher are timed from which event?

• A. From when the infielders take their positions.
• B. From the first throw.
• C. From the start of the inning.
• D. From the pitcher's arrival at the mound.

Answer: (B)

The timing for the starting pitcher’s eight warm-up throws begins with the first throw. Starting the clock at the moment the pitcher first throws to the catcher marks the actual on-field warm-up period and provides a consistent measure of how long the pitcher has to loosen up before facing batters.

If the clock started when infielders take their positions, at the start of the inning, or when the pitcher arrives at the mound, it would mix in other actions or delays (positioning, pregame setup, bullpen activity) that aren’t part of the pitcher’s warm-up sequence. The first throw is the moment the warm-up begins on the field, so it’s the correct starting point for timing.
