What can the head coach do to intentionally walk Player White?

To intentionally walk Player White, the correct procedure is for the head coach to request the umpire to award him first base. This is part of the rules that allow a coach to bypass the normal pitch process when they wish to intentionally walk a batter. This means the player does not need to face any pitches, and it ensures that the intentional walk is executed efficiently and according to the established rules of the game.

The act of intentionally walking a batter is not done through a physical execution of throwing four balls outside the strike zone, as that would risk wild pitches or other unintentional situations. Additionally, signaling the pitcher to throw to first base does not relate to the intentional walk process at all, as it focuses on a pickoff play rather than allowing a batter to advance freely. Finally, substituting another player to bat does not apply in this scenario because the intent is to walk the specific player rather than replace him with someone else at the plate.

In summary, the proper approach for the coach to intentionally walk the batter involves a simple request to the umpire, allowing for a direct and straightforward resolution in line with the game's rules.
