Tim Henman produced a gritty fightback against Sebastien Grosjean to earn a place in the last 16 of the Paris Masters.
The British number one came from a set down to beat the French seventh seed 3-6 6-4 7-5 on Wednesday.
It was sweet revenge for Henman, who lost his last two clashes with Grosjean, including a quarter-final encounter at this year's Wimbledon.
He now faces Gustavo Kuerten in the third round.
"I thought it was good tennis, not great tennis, but in beating Grosjean in front of his home crowd in Paris there was an element of revenge," said Henman.
"I would have much rather won one of those matches at Queen's or Wimbledon, but regarding my whole 2003 season it was great to beat someone like Grosjean at home.
"I had a difficult start in that match, but I then got much better groove on my serve and served much better in the second.
"I started to put pressure on him. The third set was a bit of a roller coaster again.
"But the win is a confidence booster for me, irrespective of how I do in the tournament, it sends me into the off-season with some positive thoughts."
Henman, who entered the Paris draw after Australian Open winner Thomas Johansson's withdrawal with a left knee injury, took two hours and 20 minutes to get rid of his French rival.
