The American, who beat Roger Federer in the Swiss great's last competitive match on Friday, proved a fly in Europe's ointment once again with a scintillating victory. He was outplayed in the first set but roared back to win 1-6, 7-6(11), 10-8 to give Team World an unassailable 13-8 lead. Team World, who had lost the four previous editions of the team event, began the day trailing 8-4 but Canada's Felix Auger-Aliassime stunned Novak Djokovic 6-3, 7-6(3) having earlier partnered Jack Sock to a 2-6, 6-3, 10-8 victory against Andy Murray and Matteo Berrettini.
