When a player is replaced by a pinch runner, what is the outcome for the role of DH?

When a player who is a designated hitter (DH) is replaced by a pinch runner, the designated hitter rule stipulates that the role of the DH is terminated for the remainder of the game. This is due to the fact that the DH is specifically a player who does not play in the field and focuses solely on hitting. If the DH is substituted out of the batting lineup for any reason—such as being replaced by a pinch runner—this action results in the discontinuation of the DH position. As a consequence, the team must continue the game without a designated hitter, forcing the team to use players who are eligible to play both in the field and hit in the lineup.

Therefore, when a pinch runner comes in for the DH, there is effectively no longer a designated hitter available for that game, impacting how the team manages their batting and defensive strategies moving forward.
