HAMBURG, Germany, May 5 (UPI) -- Kim Clijsters claimed her seventh career title Sunday, upsetting top-seeded Venus Williams in the $585,000 Betty Barclay Cup.
Second-seeded Clijsters, of Belgium, denied Williams her fifth title of the year, rallying from one set down to post a 1-6, 6-3, 6-4 victory. The match lasted one hour, 52 minutes.
"She played so good in the first set but I just kept fighting and did the best to raise my level," Clijsters said. "I felt more confident as the games passed. I knew I had to be aggressive from the first points on so I'm just so happy right now."
The 18-year-old Clijsters, who has struggled with injuries this year, claimed the $93,000 first prize. She also avenged a straight-set loss to Williams in the quarterfinals at the U.S. Open.
Earlier this year, Clijsters withdrew in Memphis and Scottsdale due to a leg injury. Three weeks ago at Amelia Island she advanced to the semifinals but retired in the second set against Justine Henin with a stomach virus.
"I feel good and it's a good way to go into the French Open," Clijsters said.
Despite the loss, Williams, a two-time champion of this event, will maitain her No. 1 world ranking for at least one more week.
"In the first set, I played great shots but it's difficult to keep going like that," Williams sid. "Maybe I rushed a bit too much. Kim played great tennis. She served well and moved well and was very determined."
