Courtesy runner in top of the 1st

[Dakota]

For those who have said there is no rule requiring the pitcher to face one batter, there IS a rule that requires the pitcher or catcher to face the first batter in the bottom of the 1st inning (by context, since this is in the Courtesy Runner rule, I assume this rule applies only if either player used a courtesy runner in the top of the first inning... otherwise, lineup card maneuver described in the OP is illegal. But, strictly speaking, the rule does not say that.)

Rule 8-9

ART. 2 . . . In the top of the first inning only, the pitcher and catcher are identified as those players listed on the lineup as the pitcher and catcher; both must face at least the first batter on defense. Thereafter, the pitcher and catcher are identified as the last players who physically played that position on defense. The pitcher or catcher must bat and reach base legally (or earn their way on base) in order to be eligible for a courtesy runner.
