Donald through to Match Play semis

England's Luke Donald booked his place in the semi-finals of the WGC-Accenture Match Play Championship in Tucson with a polished last-eight win over Ryan Moore.

The 33-year-old, who is searching for a first win on American soil for five years and who will go third in the world with a win in the competition, beat Moore 5&4 to send out an ominous warning to the remaining members of the field.

The win was his second-largest at the competition, not quite matching his 6&5 success over Robert Allenby a year ago, but that will have mattered little to the Hertfordshire man as he rarely gave Moore a chance.

He was four shots up on his opponent at the turn after five front-nine birdies, and carried on in a similar vein on the back nine, wrapping things up with a 15-footer with four holes to spare.

The one hole Moore did manage to win after the turn could also have gone Donald's way, with him chipping in from off the green on the par-five 11th, having driven into the sand.

"I've been working hard and it's nice to see the work paying off. I made a bunch of birdies and made it hard for Ryan," Donald told Sky Sports.

"You do the same things, try and hit it close, give yourself opportunities and put pressure on your opponent."
