No, it's not. This is covered under 6-2-4d (illegal actions with runners on,) not 6-2-1 (illegal actions.)

There was an idiot Facebook umpire (redundant, I know) that was insisting that the verbage in 6-1-2 made it an illegal pitch. I pointed out that 6-1-3 has no such wording, and thus to follow his logic, it would only be an illegal pitch in the windup and not the set.
