Scottie Scheffler has delivered all the right shots to take down Ian Poulter and then Jon Rahm, advancing to the semi-finals of the World Golf Championships Match Play.
Meanwhile, Tommy Fleetwood hit a hole-in-one on Saturday but missed out on a place in the last four.
Scheffler, heading into the final day of action, was the highest seed remaining at No.30 – but that is just a number the way he handled Austin Country Club against two of Europe’s best in this format.
The 24-year-old Texan made 15 birdies in the 31 holes required to get through his two knockout stage matches.
Poulter didn’t win a hole as Scheffler made seven birdies in a match that ended on the 14th hole.
Third-ranked Rahm was the only player ranked inside the top 20 to make the last 16 of the match play event but he could not match it with Scheffler, going down 3 and 1.
“Being able to take down those two guys, and Xander (Schauffele) in the final match on Friday, like I said before, I think my game’s trending in the right direction this week,” Scheffler said.
He advances to a final day that features three Americans and one European – Victor Perez of France, who made short work of Sergio Garcia in their quarter-final.
Matt Kuchar, the only player to win every match he has played in this most unpredictable event, pulled out a 1-up victory over Jordan Spieth in the morning and then kept Brian Harman from another amazing rally by rolling in a 10-foot birdie putt on the 17th hole of their last-eight match.
Kuchar and Scheffler will meet in one semi-final match.
Perez will face Billy Horschel, who never led in his quarter-final match until Fleetwood sent his tee shot out of bounds on their 19th hole, the par-5 12th.
Englishman Fleetwood – who missed a 12-foot birdie putt for the win on the 18th hole – had gone 67 straight holes, starting with the 17th hole on Wednesday, in which he never trailed before coming unstuck on Saturday afternoon.
Fleetwood did, however, celebrate a hole in one on Saturday, acing the par-3 4th in his last-16 win over Dylan Frittelli.
Garcia had produced a walk off ace on the same hole in a playoff against Lee Westwood on Friday.
Kuchar won the Match Play in 2013 and lost in the championship match two years ago.
With his five wins this week, he now has 33 in this tournament, second only to the 36 matches won by Tiger Woods.
