MELBOURNE, Australia -- Lleyton Hewitt was ousted from the Australian Open, his game and big plans derailed by hard-serving Younes El Aynaoui of Morocco.

	Andy Roddick had never beaten Mikhail Youzhny until his emotional comeback rally Monday.

Aynaoui, seeded 18th, eliminated the world's top-ranked player 6-7 (4), 7-6 (4), 7-6 (5), 6-4 Monday to reach the quarterfinals.

"I gave it everything I had and he was too good," said Hewitt, the 2001 U.S. Open and 2002 Wimbledon champion.

Hewitt was hoping to become the first Australian man to win the Australian Open since Mark Edmondson in 1976. He also wanted to atone for last year's Australian Open when he who lost in the first round last year while recovering from chickenpox.

"It was just too hard the way he was serving," Hewitt said. "It was a little bit out of my control."

El Aynaoui's power and consistency frustrated Hewitt, who disputed close calls, yelled at the umpire and line judges. He also became upset with a courtside photographer.

El Aynaoui, who will face Andy Roddick in the quarters, didn't drop a service game and gave Hewitt just three break point chances. The Moroccan had 33 aces -- the fastest at 131 mph -- and made 70 percent of his first serves. He also hit 24 forehand winners and set up match point with a jumping overhead smash.

Monday's highlights

Weather: Hazy; high temperature of 99. Attendance: 37,377. Stat of the day: One. The number of service breaks in the four-set, 3½-hour match between top-seeded Lleyton Hewitt and No. 18 Younes El Aynaoui. El Aynaoui eventually beat the top-ranked player 6-7 (4), 7-6 (4), 7-6 (5), 6-4 to advance to the quarterfinals of a Grand Slam tournament for only the third time in his career. Quote of the day: "The guy that just beat up on me." -- American James Blake, on how he would describe No. 31 Rainer Schuettler to someone back home after he was beaten in four sets by the German.

"I hope I didn't give away all the power I have -- there are still more matches left," said the 31-year-old El Aynaoui, who earned a standing ovation from the crowd.

On match point, Hewitt's backhand sailed wide, sending El Aynaoui into the quarterfinals of a Grand Slam for the third time. He lost to Hewitt last year in the U.S. Open quarters.

"I served well the whole way," El Aynaoui said. "The most difficult thing for me is to keep a very high level of play and Lleyton helped me a little bit. I don't think he played his best."

Hewitt lost only one service game, double-faulting on break point in the seventh game of the fourth set.

Roddick rallied to beat Russian Davis Cup hero Mikhail Youzhny 6-7 (4), 3-6, 7-5, 6-3, 6-2.

"It felt like he was playing pingpong with me in the first two sets," Roddick said. "I was actually pretty frustrated but I didn't let it get the best of me. Even when I was down I felt for some reason like I still had a chance."

El Aynaoui gave a break chance to Hewitt in the final game when his wild forehand went wide. He had recovered from 15-30 with a forehand that struck the net and dropped onto Hewitt's side of the court. The Moroccan immediately held up both hands to apologize.

Hewitt lammed a forehand into the net and then smashed his racket into the ground.

"I knew I didn't get broken the whole match and that was not the moment it was going to happen, but it almost happened," El Aynaoui said.

"I was so nervous, I was realizing I was going to win the match. I had a little bit of luck with some good serves. I kept on believing I could finish it."

The other 30-plus player through to the quarters is three-time champion Andre Agassi, who will play France's Sebastien Grosjean on Tuesday.

Germany's Rainer Schuettler beat James Blake 6-3, 6-4, 1-6, 6-3 and next faces Wimbledon finalist David Nalbandian of Argentina. Nalbandian downed sixth-seeded Roger Federer of Switzerland 6-4, 3-6, 6-1, 1-6, 6-3. Federer mixed 61 winners with 60 unforced errors.

Schuettler, 26, who had never reached a Grand Slam quarterfinal before, rebounded from early service breaks by Blake in the first two sets.

In the final set, the two traded service breaks in the fourth and fifth games, and Schuettler gained the key break in the sixth when Blake double-faulted. Schuettler finished with a forehand down the line that Blake couldn't handle at the net.

The 23-year-old Blake, playing in a Grand Slam event's fourth round for the first time, had 35 errors, compared with 19 by Schuettler.

"When you're playing for something that's really important, the quarterfinal of a Grand Slam, it hurts," Blake said. "I learned something. You can't play the same tennis in the second week as you can in the first."
