British number one Jack Draper celebrated his second ATP title following a tense straight-sets victory over Karen Khachanov in the final of the Erste Bank Open.

The 22-year-old, playing in his second competition since reaching the US Open semi-finals, won 6-4 7-5 against the Russian world number 24 in Vienna.

Draper looked set to breeze to victory after going 4-0 up in the second set but was then forced to dig in when Khachanov threatened a comeback by winning the next five games in a row.

The seventh seed became the fourth British player to triumph at the tournament, following in the footsteps of Greg Rusedski, Tim Henman and two-time winner Andy Murray.

Having already guaranteed a top-15 ranking with his performances this week, Stuttgart Open champion Draper described the match as his “biggest final yet”.

He wasted little time in asserting his authority on the contest as his stellar breakthrough season continued with a devastating first-set display.

Opponent Khachanov, who beat second seed Alex De Minaur and 2021 Wimbledon runner-up Matteo Berrettini en route to Sunday’s showpiece, was broken from 40-15 up in game three.

That proved to be the decisive moment in an opening set which was wrapped up in 40 minutes after Draper served strongly and produced an array of eye-catching winners.

Khachanov had also been serving well but showed signs of nerves when he was twice broken to love at the start of a second set to fall 4-0 behind.

The match appeared to have slipped away from the 28-year-old but he gave Draper plenty to ponder by impressively moving 5-4 ahead during a substantial momentum shift.

However, the Briton regained his composure at a crucial moment to secure his first ATP 500 title thanks to a gruelling victory in an hour and 35 minutes.
