What If the Pitcher Never Pitched

And he sat there on the mound maybe because for some reason a tie would be advantageous for his team. Think a playoff seeding scenario where a tie gives you a favoroabl outcome, or even you are so confident in your team losing that you decide to go for the tie.

You cant lose unless you give up a run. Prior to the new pitch clock I cant recall a timed rule. Even with pitch clock im sure you would walk the based but the game would never end, there would never be an out (unless hitter started doing the same thing).

There is probably a rule in place but who prompted that rule be put in place?
