Jon Rahm continued the brilliant start to his European Tour career as the knockout stages got under way at the WGC - Dell Technologies Match Play at Austin Country Club.
The Spaniard joined the European Tour on March 1 and proceeded to finish in a tie for third at the WGC - Mexico Championship later that week.
The World Golf Championships have moved north to Texas this week and after finishing the group stages with a 100 per cent record, Rahm moved three up at the turn against Charles Howell III in their last 16 encounter.
Søren Kjeldsen was also going well at two up through eight holes against William McGirt, while Americans Bill Haas and Phil Mickelson were also ahead in their matches.
Rahm soon got the putter going and holed from 20 and 28 feet on the second and third to quickly move two up.
Some bunker trouble on the fifth then led to a concession but Howell found the sand off the tee himself on the par three seventh and the cushion was re-established.
Howell then got in trouble off the tee on the ninth and a concession followed.
A McGirt bogey on the second handed Kjeldsen an early lead but the American bounced straight back with a birdie on the next.
Kjeldsen's renowned wedge play then came into force on the fifth with an approach to six feet and the lead was once again with the Dane, with McGirt bogeying the eighth.
Mickelson had a 100 per cent record from the group stage and continued that brilliant form on Saturday, winning the third and sixth thanks to excellent approaches with Marc Leishman finding the water on the fourth.
That dialled-in wedge play continued to bring him the eighth and ninth and he was in total control at four up.
Haas birdied the second to move one up against Kevin Na, who joined the Tour on the same day as Rahm, and while Na birdied the fifth, Haas won the eighth and ninth to sit two up after ten holes.
