#2 Jack Sock (Team World)

Jack Sock

Jack Sock registered his first match win at the Laver Cup when he teamed up with good friend Nick Kyrgios at 2017 Prague to beat Rafael Nadal and Tomas Berdych in a match tiebreak. It was also Team World's first match win in the competition.

In his first singles match at the Laver Cup the next day, Sock went down in a match tiebreak to Nadal 4-6 6-3 [9-11]. Sock endured his second defeat of the day in another match tiebreak when the American, with compatriot Sam Querrey, lost to Roger Federer and Rafael Nadal 4-6 6-1 [5-10].

On the final day of action in Prague, Sock combined with compatriot John Isner to beat the Team Europe combine of Tomas Berdych and Marin Cilic in two tiebreak sets for his second win in the competition.

Sock made his second Laver Cup appearance on home turf in Chicago where he lost his first match to Kyle Edmund in a match tiebreak. The American, though, turned up for double duty as he teamed with Kevin Anderson to beat Novak Djokovic and Roger Federer in a match tiebreak.

On the next day, Sock and Nick Kyrgios registered their second win in as many matches in the Laver Cup by beating David Goffin and Grigor Dimitrov in straight sets. Playing his fourth match of the competition in three days, Sock, along with John Isner, saved two match points in a thrilling 4-6 7-6(2) [11-9] match tiebreak win which handed Team Europe the lead in a Laver Cup tie for the very first time.

The Nebraska native, having dropped to a lowly 210 in the singles rankings in 2019, was chosen to make his third appearance at the Laver Cup owing to his doubles pedigree. But it was in singles where Sock first excelled, as the American beat Fabio Fognini in straight sets to become the lowest-ranked player to win a singles match at the Laver Cup.

Later in the day, Sock and Denis Shapovalov went down in straight sets to Roger Federer and Sascha Zverev. On the second day of the competition, Sock combined with Kyrgios and improved the pair's perfect record at the Laver Cup to 3-0 by beating Rafael Nadal and Stefanos Tsitsipas in a match tiebreak.

On an eventful final day of action in Geneva, when two players (Nadal and Kyrgios) withdrew from the competition due to injuries, Sock became the first player in Laver Cup history to register eight match wins as the American, with compatriot John Isner, beat Federer and Tsitsipas in a match tiebreak to provide an 8-7 lead in the tie to Team World.

The win improved Sock's Laver Cup record to 8-4.
