They said on TV that He came from open wheel racing. Does anyone know type and/or league?

I think they were mistaken, I think he ran Late models. His dad or Grandpa is Harold Annett who ownc TMC Trucking that sponsored Sammy.

He did run at least one SC race last year.

BTW, why on Nascar TV shows is Dave Blaney always a WoO champ, and they never mention him being a USAC SC champion? What dummies.

Harold is Michael's Dad.

HUMMMMM I'd say cause he is known more for the WoO title than the USAC title.
