Team Europe took a commanding 3-1 lead over Team World in the Laver Cup on Friday, despite seeing their high-profile doubles pairing of Roger Federer and Novak Djokovic suffer the defending champions’ only defeat of the first day in Chicago on Friday. Jack Sock and Kevin Anderson combined to deliver the sole triumph for their side, overcoming the world’s second and third-ranked singles players 6-7(5) 6-3 (10-6) to prevent an opening day shutout for Team Europe.

Europe had earlier built their advantage on singles victories for Bulgarian Grigor Dimitrov, Briton Kyle Edmund and Belgian David Goffin. Dimitrov rolled through the opener with a 6-1 6-4 victory over American Frances Tiafoe before his team mates were required to dig deeper for their wins.

Edmund overcame Sock 6-4 5-7 (10-6) despite struggling with his serve at times and coughing up four double faults, before Goffin staved off a late rally on his way to a 6-4 4-6 (11-9) triumph over Argentine Diego Schwartzman

Day Two will feature three more singles clashes, including Federer v Nick Kyrgios, and an additional doubles match, with two points on offer for any victory. Sunday’s four matches are worth three points apiece with the first team to reach 13 points crowned champions after Europe claimed last year’s inaugural event by a 15-9 margin in Prague
