British number one Jack Draper reached his third ATP final of the year with a straight-sets victory over Lorenzo Musetti at the Erste Bank Open.

The 22-year-old, playing in his second tournament since reaching the US Open semi-finals, triumphed 6-2 6-4 against the Italian world number 17 in Vienna.

But the scoreline did not tell the story of a gruelling encounter taking an hour and 48 minutes.

Having broken Musettiā€™s serve in the opening game, Draper recovered from being broken back to reel off four games in a row and take the first set.

Musetti, a Wimbledon semi-finalist this year, dropped serve again early in the second.

Draper, who had won their previous two matches, came through two taxing service games but Musettiā€™s pressure told when he levelled at 4-4.

However, the momentum swung dramatically back in Draperā€™s favour thanks to a wretched service game from Musetti.

A clearly exhausted Draper took a medical time-out at 5-4 but came back out to wrap up victory and reach his first final at ATP 500 level.

Draper, now up to 15th in the live world rankings, told Sky Sports: ā€œI thought the first set was really high level from my side.

ā€œLorenzo is a really tough competitor and the second set was up and down, some nerves and some difficult moments. Luckily in the end I got it done.ā€

Draper is the fourth British player to reach the final in Vienna after Greg Rusedski, Tim Henman and two-time winner Andy Murray.

He will face Russian Karen Khachanov, who beat second seed Alex De Minaur 6-2 6-4, in Sundayā€™s showpiece as he bids for a second career title following his summer win in Stuttgart.

ā€œI suppose itā€™s my biggest final yet,ā€ he added. ā€œTo be in the final of a 500 after the season Iā€™ve had, Iā€™m incredibly grateful.ā€

There was disappointment for British number two Cameron Norrie, who lost 6-3 6-4 to Franceā€™s Quentin Halys in qualifying for the Paris Masters.
