Title: Home run
Passage: A home run accomplished in any of the above manners is an automatic home run. The ball is dead, even if it rebounds back onto the field (e.g., from striking a foul pole), and the batter and any preceding runners cannot be put out at any time while running the bases. However, if one or more runners fail to touch a base or one runner passes another before reaching home plate, that runner or runners can be called out on appeal, though in the case of not touching a base a runner can go back and touch it if doing so won't cause them to be passed by another preceding runner and they have not yet touched the next base (or home plate in the case of missing third base). This stipulation is in Approved Ruling (2) of Rule 7.10(b).
Question: do you have to touch the bases on a home run
