Kim Clijsters made a fine start to her final Wimbledon campaign as she dumped out 18th seed Jelena Jankovic on the opening day.
The Belgian crowd favourite has already announced she will retire for good after the US Open later this summer but she gave notice she could be a threat at the All England Club with a 6-2 6-4 victory.
Clijsters dominated a first set of varying quality and then withstood a Jankovic fightback in the second to move through to a second-round match against Czech Andrea Hlavackova.
The 29-year-old, who retired for the first time in 2007 before returning to the circuit two years later, missed Wimbledon last year with an ankle injury and has played only four tournaments this season because of a hip problem.
She returned from three months out last week on the grass in 's-Hertogenbosch, and then pulled out with a recurrence of a stomach muscle problem, but she began impressively on Court One, winning the first three games.
Jankovic, like her opponent a former world number one, has struggled for form for many months and she had no answer to Clijsters, who took the set with a clinical forehand pass.
It was a rough draw for Jankovic, with Clijsters unseeded having dropped to 47th in the rankings, but the Serbian responded well at the start of the second set and broke her opponent's serve for the first time to lead 2-1.
However, she could not cement it, and Clijsters promptly went on a run of three straight games and had a number of chances to lead 5-2.
Back came Jankovic, though, levelling at 4-4 only to crumble when she served to stay in the match, and a rather apologetic forehand into the net handed the crucial game to Clijsters.
Clijsters said: "The matches that I've played against her have always been tough so when I saw the draw I knew it was going to be difficult but I also really looked forward to playing her.
"In the beginning we both had to look for our game a bit but I felt better and better out there."
Clijsters has twice reached the semi-finals at Wimbledon, in 2003 and 2006, while on her most recent appearance in 2010 she lost in the quarter-finals to Vera Zvonareva.
