Huge hold from Rowlands.
Kateley again puts the pressure on with his high scoring early in the leg, but just can't see it out when it matters.
Tops for the Welshman - game shot. He's now one leg away from the quarters.
Kateley knows how close that was.
Almost a massive 153 checkout, but double 16 - again - goes begging.
Rowlands makes him pay. The Welshman now just one set from victory.
Suddenly nobody can hit a double again.
Kateley with a huge chance to level it at 2-2, but double 16 and double 8 both go begging.
Rowlands - eventually - shows him how it's done. A massive leg coming up.
Kateley's comeback continues.
He averaged over 105 in the first stages of this match but just couldn't buy a double.
No issues this time as D16 goes at the first attempt. That's three legs on the spin for The Robot.
Debutant Andrew Kately has just got himself back in contention against Welshman Richard Rowlands.
Here's how the rest of today's matches have ended in Sunderland, with an evening session starting from 7pm.
