A red-hot Marc Leishman has moved on to the round of 16 at the World Golf Championship matchplay event, unbeaten after wiping the floor today with brilliant American Bryson De Chambeau in Texas.

Leishman easily defeated world 6, five and four, needed only 14 holes to secure his place in the next round and set up a collision with South Africa & Louis Oosthuizen.

A two-putt on the par-four 14th was enough for the third round victory, the Australian had beaten Scotsman Russell Knox and Thailand's Kiradech Aphibarnrat in the first two games of the round robin. The man from Warrnambool, placed 17th this week at Austin Country Club, made four birdies and an eagle in the first six holes of the game to achieve a lead of four and was never threatened from that moment on. He was six under-through 14 holes today.

From here, however, it is a sudden death and Oosthuizen, who today beat Tommy Fleetwood four and three, is also in a warm shape.

Former world number 1 Tiger Woods also continues to the next round and plays the unbeaten Rory McIlroy tomorrow in the tent game. The Swedish Henrik Stenson and the Branden Grace of South Africa also went unbeaten by the round robin.

Among those who missed the knockout phase, world number one Dustin Johnson and Jon Rahm from Spain along with world number 5 were Justin Thomas.

Jason Day lost his third consecutive game, this time to Phil Mickelson, in what was a worrying run-up to the Masters in less than two weeks. Comrade Queenslander Cameron Smith had already lost his chances of progress and was behind early against the Englishman Paul Casey.

Meanwhile, Aaron Baddeley is in a strong position in Mexico Australia through two rounds of the Corales tournament in the Dominican Republic.

Baddeley shot a second round 67 to be an equal second, just a shot from the lead. Matt Jones, the leader of the first round, slipped to eighth after taking a nine at the par-four tenth hole.
