Since Smith's second title in 2008, though, there have been four different champions: Mikesh Desai of Central; Max Lillie of Dallastown, Tommy Nicklas of South Western and Anthony Miserendino of South Western.

Miserendino returns this year as the No. 1 seed, and he'll seek to join Holmes, Bayliss, Heird and Smith as a recent repeat champion.
