MELBOURNE, Jan 31: Normally ruthlessly calm, Justine Henin-Hardenne admitted to suffering from nerves and high emotions as she fought to win her first Australian Open title on Saturday.

What started as a lop-sided women's singles final between the world number one and fellow Belgian Kim Clijsters reached a dramatic climax at Melbourne Park.

"That's just unbelievable. Three grand slams in six months is amazing for me," Henin-Hardenne told reporters following the 6-3 4-6 6-3 win.

Clijsters, yet to claim a major title despite meeting Henin-Hardenne in three of the last four grand slam finals, twice fought back before Henin-Hardenne clinched victory.

"I was very emotional, I thought I couldn't close the match," said Henin-Hardenne, who also holds the French and U.S. titles.

"We were nervous, the both of us. It probably wasn't a good match of tennis."

Henin-Hardenne, 21, appeared to be heading for an easy win when she raced through the opening set.

When a tentative Clijsters surrendered her serve in the sixth game of the second set, another straight-sets victory in a grand slam final seemed inevitable for Henin-Hardenne.

However, second seed Clijsters fought back, breaking Henin-Hardenne for the first time in the match in the next game and going on to win the set as the tension grew.

When Henin-Hardenne regained the initiative to grab a 4-0 lead in the third set, the match appeared over.

Clijsters charged back yet again, breaking Henin-Hardenne to take three successive games.

Clijsters's fiance Lleyton Hewitt nervously looked on and most of the Melbourne Park crowd were firmly behind their adopted daughter, adding to Henin-Hardenne's nerves.

Emotions ran higher still when Henin-Hardenne held a break point in the eighth game and Clijsters's volley clipped the outside of the baseline but was overruled by the umpire.

"The umpire took her responsibilities and I think that it was a very tough call but I think it was just long," Henin-Hardenne said.

The break secured, Henin-Hardenne served out for victory.

Henin-Hardenne said winning Wimbledon, the only grand slam title to elude her so far, was a priority, as was matching Venus and Serena Williams when the injured sisters return.

Henin-Hardenne credited her success to the extra physical work she has been doing since last year.
