World number one Scottie Scheffler and Rory McIlroy both progressed to the knockout stage at the WGC-Dell Technologies Match Play Championship with perfect records in Austin, Texas.
American Scheffler beat Tom Kim 3&2 to win his third successive match and top Group One as he reached the last 16.
Third-ranked McIlroy won 3&2 against Group Three opponent Keegan Bradley.
However, England’s US Open champion Matt Fitzpatrick is out, as is Spanish world number two Jon Rahm.
Fitzpatrick lost his must-win match against Sahith Theegala 2&1 – although ultimately that did not matter as J.J Spaun beat Min Woo Lee 2&1 to win his third successive match in Group 11.
Rahm, who also needed to win his final match, saw his hopes ended in a 5&4 loss to Group Two winner Billy Horschel.
Meanwhile, three-time major winner Jordan Spieth fell to a 2&1 defeat by already eliminated former Open champion Shane Lowry.
Canada’s Mackenzie Hughes thrashed Taylor Montgomery 6&4 to set up a play-off with the American in Group 12, which he won to top Spieth’s group.
Fourth-ranked Patrick Cantlay was another to end the group stage with a clean-sweep of wins, beating Brian Harman 2&1, as did fellow American Max Homa.
Homa was the first player to secure his place in the knockout stage on Friday and he did so without hitting a shot, after opponent Hideki Matsuyama was forced to withdraw with a neck injury.
Matt Kuchar is on the verge of history, with his 7&6 win over Kim Si-woo tying him level with Tiger Woods for the most wins (36) in the event’s history.
England’s Tyrrell Hatton suffered a third straight defeat, losing 3&2 to Russell Henley, while compatriot Tommy Fleetwood’s challenge was ended by Im Sung-jae 4&3.
