Gurney was behind for the whole match until he pulled ahead by breaking West's throw to go within one leg of victory and he hit his trusty double 16 to claim the win.
Both players were emotional at the end with Gurney dropping to his knees in victory while West looked devastated as he should be into the second round of the
