Was this battle winnable against Factory Head Thorton?

So I was playing the battle factory and was using my starters: Aggron, and Lickilicky and a random Bellosom for my lead. Thorton was rocking aCrobat, Rhyperior, and Toxicroak.

So turn 1, I immediately switch out to Aggron. Turn 2 I Rock Slide-MISS Turn 3 Thorton switches to Rhyperior.

So was this battle winnable or did I mess up?
