Jack Sock has completed a perfect sweep of his round robin singles matches at Mastercard Hopman Cup with a 6-2 6-2 win over Nick Kyrgios.
With USA already having already earned its place in Saturday’s final, it was a relaxed Sock who took to the court against Kyrgios, the 24-year-old showcasing some of his flashiest stroke-making as he completed the win in 49 minutes.
Kyrgios, who has played with his knee heavily strapped in his last two matches, had until then enjoyed an unbeaten singles run in two Mastercard Hopman Cup appearances.
Sock gained the ascendancy early, gaining breaks of serve in the third and seventh game of the first set and Kyrgios holding serve only once in the 27-minute second set.
After Daria Gavrilova levelled the tie with a 6-4 4-6 7-5 win over CoCo Vandeweghe, the tie came down to a live mixed doubles rubber.
USA claimed the tie 2-1 after a 4-1 4-1 win over Gavrilova and Matt Ebden, who replaced Kyrgios in the final match.
