Josh Rock will feel slightly hard done by because every single leg that could possibly have been played in this match has been played. It's come down to last-leg deciders in the first two sets.

I've got a good feeling about Rock this year. All year round he's looked strong, played well and been a real threat to anyone, even the big players like Humphries and Littler. I don't see why he can't go all the way.

An 11 dart break to win a set against someone averaging about 105 is world class. Happy Feet can beat anyone playing like that.

Both men are averaging over 100 after the first set. This one could turn into a classic.
I wouldn't mind a match like Hood's against Danny Noppert earlier in the tournament. That was incredible.
