Belgium's Justine Henin recorded a sensational straight-sets win over 1994 Wimbledon champion Conchita Martinez.

The 19-year-old totally dominated the experienced Spaniard throughout the match and breezed through to the semi-finals for the second time in consecutive Grand Slams.

Martinez won the first game of the match, but that was the only success she was able to enjoy as Henin racked up 12 consecutive games.

"I'm so happy to be in the semi's," said Henin. "It was an easy match in terms of the score but I had to play a good match to win so easily."

"Now I have more experience I can enjoy this moment more than I did at the French," she said. "I didn't enjoy it enough at the French and I don't want to do the same thing here."

Martinez is in no doubt that Henin has the ability to go one step further than in France.

"She's got a great chance if she plays aggressively. She can beat anyone, she's a great player."

The pattern was set in the third game when Martinez started with two double-faults to hand the initiative to Henin, and the Belgian never looked back after saving a break-point in the following game.

Martinez increasingly showed her frustration as she failed to get her game together in the face of the her opponent's remorselessly accurate ground strokes and powerful backhand.
