Illegal pitch/delay dead ball

[Gleighty]

Not sure this is relevant or not, but USSSA rule 8.08.E (amended September 2008), which addresses balks, indicates that the penalty shall be:

The ball is dead, and each runner shall advance one (1) base without liability to be put out, unless the batter reaches first (1st) on a hit, an error, a base on balls, a hit batter, or otherwise and all other runners advance at least one (1) base, in which case the play proceeds without reference to the balk.

Would this also include and illegal pitch?

In a USSSA 12U baseball game, a pitcher dellivers an illegal pitch. Umpire signal dead ball, but he pitcher delivered the pitch. The batter hits the ball and reaches first base. Umpire indicated a this was a delay dead ball situation and allow the play to stand. Would this be a delay dead ball situation and the batter/runner be allowed to stay on first base?
