After last night's stunning victory over Todd Martin at the XL Bermuda Open -- only his third career ATP win against a Top 20 player -- Michael Tebbutt is certain to be referred to from now on as Mr. Tebbs.

Tebbutt, ranked 102 in the world, beat Martin, ranked 14 on the pro charts, to become the third Aussie to gain entry into the exclusive quarter-final club with a 7-5, 6-3 victory over the Open's number one seed.

Earlier in the day Jason Stoltenberg and Jamie Morgan, also of Australia, won their matches to join the final eight.

In similar fashion to his first match on Monday, Tebbett, 24, did it once again with his main weapon, a devastating serve (it was clocked at 121 miles per hour on match point) and he will now meet Bryan Shelton of the US.

Astoundingly, the six-foot-three native of Sydney is playing in only the first clay court ATP tournament. He'll attempt to reach his first-ever semi-final -- he's advanced to three previous quarter-finals, one of them coming in Sydney earlier this year. Besides Martin, Tebbutt's other Top 20 victims have been Sergei Bruguera and Andre Medvedev.

Tebbutt, looking relaxed and displaying nerves of steel, spent the afternoon watching Morgan and then "went to the beach for a couple of hours and drove to the west end.'' He drove Martin to frustration, winning three of five break points in the one hour, 16 minute match before a packed house at Coral Beach and Tennis Club.

"It feels great, I was so up for the match and I've never been that up for a match ever,'' said Tebbutt afterwards. "I'm just ready to make a move and instead of winning one match in a tournament I'm ready start to a final. I just felt like I had to start sometime and this seemed like a good time. I really wanted to win badly.'' Martin's anger boiled over in the seventh game of the second set when he slammed his racquet and was cited for a court violation.

"I'm just mad at myself,'' said a subdued Martin in the dressing room later.

"(Tebbutt) served very well tonight and, more importantly, he backed it up pretty well and played some good games on my serve.

"I don't feel real good about the way I'm playing, not necessarily about the way I'm hitting the ball. I don't think I'm 100 percent there point in and point out. I'm making a lot of stupid mistakes and that's really, extremely frustrating.

Stoltenberg, who used this same event as a springboard to bigger and better things when it was held in Birmingham, Alabama, a year ago looks to be on much the same track after an solid 6-2, 6-4 win over Spain's Jordi Arrese on Stadium Court earlier yesterday.

With a similar tour ranking and age (25), Stoltenberg will now face Javier Frana of Argentina in the quarter-finals, who was a 6-0, 6-3 winner over Karim Alami of Morroco.

Morgan, 23, overcame 2-4 and 1-5 deficits in the second and third sets of his match against Radomir Vasek of the Czech Republic to rebound 2-6, 6-4, 7-6 (7-2) in the Open's most spectacular comeback story so far.

In other afternoon singles clashes, Colombian Mauricio Hadad beat Lars Jonsson of Sweden 2-6, 6-3, 6-1; Vince Spadea of the US defeated Christian Bergstrom of Sweden 6-2, 6-2; Karsten Braasch of Germany swept qualifier Marcio Carlsson of Brazil 6-3, 6-3 and Bryan Shelton of the US bounced Czech Bohdan Ulihrach 6-2, 6-2.

All eight players are first-time quarter-finalists in Bermuda, but four (Hadad, Shelton, Spadea and Braasch) have played here before. Only three players -- Shelton, Frana and Stoltenberg -- have won tournaments.

Officials from the United States Tennis Association (USTA), however, have reason to be pleased since two Americans, Spadea and Shelton, remain in the hunt for a semi-final berth. The final four will be determined today.

"Hopefully we can all do well here,'' said Stoltenberg of the Australian muscle. "But I'm worrying about myself and thrilled to get through two matches here. I'm just taking it one at a time.'' Stoltenberg played his second strong match in a row, a win against qualifier Lou Gloria already under his belt. The victory against Arrese was far sweeter, however, considering Arrese's strong clay court background with 201 victories on the surface.

Stoltenberg needs 189 more wins on clay to catch up to Arrese and he wasn't prepared to trumpet his early success at the Open.

"I've got a long way to go yet,'' he said. "I'm only in the quarter-finals ...I've only won two matches and that's not enough for me and I want to win more.

"(Arrese) is a good clay court player so it gives me a lot of confidence that I can beat someone of his calibre.'' Morgan's confidence also received a substantial boost as he nibbled away at what looked like a certain victory by Vasek. In the dressing room afterwards, ATP trainer Bill Norris stretched Morgan's legs almost as much as the player, ranked 101 on the tour, stretched a disappointed Vasek.

"(Vasek) was up like double break in the second and I don't know how I got out of that set,'' said Morgan. "And then I was down 5-1 in the third. The guy was playing well, he was hitting the ball so deep. I was struggling a bit and I wasn't serving very well then I started to hit the ball a little bit harder and started to go for my shots a little bit more. He probably got a little bit tight.

"It felt like I couldn't hit the ball. I actually asked the umpire whether the balls were flat or not.'' Ulihrach, who ran around the court as part of warm-up exercises prior the match, was constantly kept on the run by Shelton.

The 29-year-old native of Atlanta looked unbeatable.

Even when he managed to get himself into trouble, which rarely happened, the personable Shelton was able to shrug it off with ease.

Down 0-40 in the fifth game of the second set, Shelton roared back to win, walloping one of his six aces in the match to take a 4-1 lead in the set.

"That was the key today, especially when I was down 0-40 in that game,'' Shelton said. "That was the make or break point for me.'' Shelton, 8-8 in 1995 after an 0-3 start and ranked as high as 55 three years ago, would like nothing better than to improve on his current status of 90. A popular figure with local fans, Shelton has seemingly found a comfortable groove on the Coral clay.

"Aw, man, I'd love it,'' said Shelton, flashing a wide smile. "If I felt like this every match boy I'd be in good shape. I was serving well, volleying well and playing well from the back. I made a lot of first serves out there.

"I wasn't 100 percent when I came here last time, I had some trouble with my shoulder,'' he said. "But, yeah, I feel really confident with my game right now. Last time I was here I wasn't real confident because I had just come off a break and right now I'm coming into my stride. I'm feeling good with my game and feeling confident everytime I walk out onto the court.'' Spadea squared his life-time record against Bergstrom to 1-1. "I thought I played pretty solid, I was out their playing pretty aggresively, focussing well and moving well. And when you do those things and you wait for your opportunities to attack and you don't make a lot of errors you're going to be doing pretty well...at least be competing pretty well in the match.'' Tennis great Rod Laver won't be coming to Bermuda because his wife suffered a heart attack and is in a California hospital.
