Alexander Zverev becomes Germany’s first Olympic men’s singles tennis champion

The fourth seed, who ended Novak Djokovic's Golden Grand Slam bid in the semi-finals, produced a dominant display to win 6-3, 6-1 over Karen Khachanov

Alexander Zverev of Germany reacts after winning his gold medal match against Karen Khachanov of the Russian Olympic Committee.

Alexander Zverev brushed aside Karen Khachanov in straight sets on Sunday to seal the Olympic men's singles title and win Germany's first tennis gold since 1992.

The fourth seed, who ended Novak Djokovic's Golden Grand Slam bid in the semi-finals, produced a dominant display to win 6-3, 6-1 after just 79 minutes on court.

Zverev becomes only the second German to win an Olympic singles gold after Steffi Graf in 1988, while Boris Becker and Michael Stich took the men's doubles crown four years later.

The world No 5 is still waiting for a maiden Grand Slam title after several near misses, including when he blew a two-set lead to lose to Dominic Thiem in last year's US Open final.

However, the 24-year-old can add this victory to his 2018 ATP Finals triumph and his four Masters titles.

Khachanov had continued his return to form in Tokyo from recent weeks after reaching the Wimbledon quarter-finals, but this match proved a step too far for the player representing the Russian Olympic Committee.

Zverev made short work of the final, crushing six aces and 16 winners past his overwhelmed opponent.

He struck first blood with a break in the third game and then importantly saved a break point to take a 4-2 lead.

Zverev did not let up the pressure from there and brought up a set point in the ninth game, and although Khachanov recovered initially, a successful review gave Zverev a second chance.

He capped an excellent opening set as Khachanov sent a stretching volley spinning into the tramlines.

Khachanov, the world No 25, may have hoped for some respite from the other side of the net early in the second set, but a blistering backhand winner up the line gave Zverev a hold to love.

Zverev took total control of the match just minutes later, taking his third break point after more clean hitting from the baseline when Khachanov netted.

The 25-year-old Khachanov's gold-medal hopes were all but ended as Zverev's brilliant backhand helped him into a 4-0 advantage as he broke again following a gruelling rally.

A hold to love put Zverev on the brink of gold, and he held his nerve with some big serving – his gold medal confirmed on a first match point as Khachanov hit the net.
