David Goffin has given Team Europe a 3-0 lead after beating Diego Schwartzman on the first day of the Laver Cup.

In the third singles match of the day, the Belgian helped the defending champions take an early lead over Team World with a 6-4 4-6 11-9 win over the Argentine.

Earlier, Britain’s Kyle Edmund regained command in a tiebreaker before beating American Jack Sock as Team Europe took a 2-0 lead.

Edmund’s 6-4 5-7 10-6 victory followed Grigor Dimitrov’s 6-1 6-4 win over Frances Tiafoe of Team World in the opener at the United Centre.

Edmund broke Sock’s service to capture the first set 6-4. Sock, who came out to warm up wearing a Chicago Bulls jersey over his shirt, fought back and broke Edmund to go up 6-5 in the second set before serving it out as the crowd came alive.

Edmund then raced to a 7-2 lead in the 10-point tiebreaker that is used in the Laver Cup when the first two sets are split.

Sock was to play doubles later Friday with Kevin Anderson against Team Europe’s star pairing of Roger Federer and Novak Djokovic.

Dimitrov had 13 winners and two service breaks to win the first set 6-1, finishing it off with one of his five opening-set aces.

Tiafoe was a late replacement for Juan Martin del Potro on Team World.

The 20-year-old American played in the Davis Cup semi-finals last weekend in Croatia, losing the deciding match in five sets to Borna Coric.

He played much tougher in the second set on Friday against Dimitrov, getting a service break for 4-4 before Dimitrov broke back and served out the victory in a match that featured extended baseline rallies.

Up next, Roger Federer and Novak Djokovic pair up for Team Europe to take on Sock and Kevin Anderson in the doubles.
