Andy Murray came from a set down to beat David Ferrer 5-7 6-2 7-5 in the final of the Vienna Open.
The victory means he moves ahead of the Spaniard in the race to qualify for the World Tour Finals.
Murray, 27, broke his opponent three times in the final set before serving out the match to win only his second title of the year.
The win means the Briton leapfrogs Ferrer, 32, and moves up to eighth in the race to London.
The top eight players at the end of the regular season will qualify.
"It was a good finish to the week," Murray told BBC Radio 5 live after a match lasting two hours 42 minutes.
"Obviously, it was an important match in the race for the Tour Finals in London and it was a very, very tough match but I managed to get through it.
