Doubles specialist Paul Haarhuis shocked defending champion Jim Courier 6-4 7-6 (7-2) to win the Masters Tennis event at London's Royal Albert Hall. Haarhuis, 39, only retired from the main ATP Tour in 2004 and appeared for Holland in the Davis Cup this year.
The Dutchman, a 40-1 outsider at the start of the week, broke Courier's serve twice to take the first set.
Courier saved three breaks points in the sixth game of the next set, but lost two mini-breaks in the tie-break.
The 35-year-old American admitted he had been outplayed by his older opponent, who he had described as "a dangerous floater" before the event.
"The better man won," he said. "Paul played beautifully, he didn't give me any unforced errors.
"We played a couple of times this year and I knew he was playing really well. I didn't quite have the pop on the serve and he was so sharp."
Haarhuis, who won doubles titles at all four Grand Slams, said: "Winning this tournament is a big thrill.
"I was just hoping to stay with him but I was winning my points so I was feeling good."
