If all runners attempt to tag up but R1 leaves first base early, what happens after appeal?

In this scenario, the situation revolves around a tagging up rule during a fly ball. When a runner leaves a base early on a tag-up and the defensive team makes a proper and timely appeal, the runner who left early is subject to being called out.

By calling R1 out due to leaving first base early, the appeal effectively negates R1's attempt to advance, which means that the run scored by any other runners on this play cannot count. This is because the out occurs at the base that R1 vacated illegally, and the appeal serves as a recognition of this infraction. Consequently, since R1’s action of leaving early leads to the issuance of an out, it impacts the status of all subsequent runs scored, thereby ruling that the run does not count.

This interpretation aligns with the rules that govern tag-ups and appeals in baseball, ensuring that all players adhere to the legal conditions for advancing on a batted ball.
