London: Kim Clijsters, playing her final Wimbledon before retirement, reached the second round on Monday with a 6-2, 6-4 win over Serbian 18th seed Jelena Jankovic.
Clijsters, unseeded this year, will face Andrea Hlavackova of the Czech Republic for a place in the last 32.
The Belgian, a four-time Grand Slam title winner and a Wimbledon semi-finalist in 2003, had come into the tournament under an injury cloud.
A stomach strain had caused her to pull our of her 's-Hertogenbosch semi-final at the weekend in what was her first event since March.
But the 29-year-old, who will quit for a second and final time after the US Open, was untroubled against the error-plagued, former world number one Jankovic who lost in the first round for a second successive year.
"When I saw the draw I knew it was going to be a tough one but at the same time I really looked forward to playing her," said Clijsters after her eighth win in nine meetings with Jankovic.
