Lukas Rosol resolute for more

WIMBLEDON, England -- George Bastl. Peter Doohan. Ivo Karlovic. And now Lukas Rosol.

When a fearless Rosol blasted his way past 11-time Grand Slam champion Rafael Nadal in the second round at Wimbledon Thursday, he joined that trio in authoring one of the biggest upsets in tournament history.

Including qualifying, Rosol hadn't won a match at Wimbledon prior to this year, and he'd tallied only 19 top-level victories -- in his career -- entering his battle with Nadal. At age 26, Rosol was the classic journeyman.

The Czech was back at the practice courts late Friday morning, preparing with partner Mikhail Kukushkin for a doubles encounter. The eyes of the world were watching like never before.

First, Rosol did an interview with Swedish television. Then, he hit with Kukushkin as the heavens spat. Giving way on practice Court No. 3 to compatriot Petra Kvitova, he was greeted by more cameras.

Rosol happily did at least four more interviews, and in one, revealed he'd had a late night.

"I went to sleep at 3 o'clock in the morning," he said. "I hope [my tournament] isn't finished yet and I can continue like this. Every single match, every single point, I have to concentrate."

Nadal, meanwhile, was in a taxi at 4:30 a.m., bound for the airport, on his way back to Spain.

Rosol's next opponent is Philipp Kohlschreiber; they're the last two players to beat Nadal, with Kohlschreiber triumphing at a Wimbledon warm-up on home soil in Halle, Germany.

ESPN.com gathered reactions from several people with ties to Rosol. They discussed Thursday's massive upset, Rosol's past and his future.

Philipp Kohlschreiber: The next challenge

Even though Kohlschreiber toppled Nadal in Halle, he knew he was lucky. He'd much rather face Rosol. Kohlschreiber, a good pal of Roger Federer's and the owner of a picturesque one-handed backhand, is 0-6 against Nadal in majors and Masters events.

Kohlschreiber, who channel-surfed Thursday, switching between tennis and Germany's European Championship soccer semifinal against Italy, is feeling more optimistic.

"Now I think the chances are more even," Kohlschreiber, who has never faced Rosol, told ESPN.com. "Everything changed a little bit because no one expected him to be in the third round. I'll try to play a bit different than Rafa did, trying to slow down his speed with a little bit more slice. I'm a right-hander. Maybe he plays better against a left-hander, I don't know.

"He hits every ball full power, and yesterday was maybe his best tennis ever in his life. Hopefully he's not doing this against me, but you never know."

Ivan Dodig: Rosol's first-round victim

When the draw came out last week, Croatia's Ivan Dodig was thought to be the more dangerous potential opponent for Nadal in the second round. Dodig, after all, upset him last summer at the Canadian Masters in Montreal.

But Rosol prevailed Tuesday in the first round 6-4, 3-6, 7-6 (0), 7-5. His first-serve percentage, percentage of points won behind the first serve and percentage of points won behind the second serve were almost identical to Thursday's match.

Dodig, interestingly, out-aced Rosol 27-12.

"He played the same against me as he did against Nadal," Dodig told ESPN.com. "He was serving good and hitting every ball [hard]. It's a big surprise that he beat Nadal, but I would say, too, that everybody can beat everybody. He probably is feeling good."

David Goffin: A former foe

In the first round of qualifying at Wimbledon in 2011, Rosol won only one set -- against David Goffin, one of the tour's up-and-comers.

Goffin remembered their tussle here well, and he's lost to Rosol twice this year on clay.

"It's true, he hits very, very hard," Goffin told ESPN.com. "His only chance to beat Nadal was to hit very, very hard and not give Rafa a rhythm. He served well. Hats off to him."

Slava Dosedel: The coach

How high can Rosol go in the rankings?

"Lukas can be a top-20 player, but he has to train properly," his coach, former pro Slava Dosedel, told reporters in Czech.

Dosedel and Rosol worked together when Rosol was younger, but split for four years before reuniting this year. In his session with the Czech reporters, Dosedel added that while Rosol competes at 100 percent in matches, he needs to organize his "tennis life" better.

Mikhail Kukushkin: The doubles partner

Kukushkin, who was sitting in the players' box, garnered almost as much air time as Rosol on Thursday. A player with a similar style to Rosol, albeit without the monstrous serve, Kukushkin was thumped by Nadal 6-1, 6-1 in Monte Carlo two months ago.

"Before the match, of course Lukas asked me how to play against him," Kukushkin told ESPN.com. "He said, 'What's his weakest and best shots?' I gave him some advice, but he has a coach and I think they had a good strategy. He was playing good but also pretty smart tennis.

"If he continues to play like this, of course, he'll have good chances" against Kohlschreiber, Kukushkin said. "He'll have to concentrate on his game and can't be [content] with yesterday's win."

Andreas Seppi: Davis Cup rival

Like Kohlschreiber, Seppi was glued to Italy's soccer match with Germany. His first language is German, but Seppi, an Italian, vows he was rooting for the Azzurri.

When the semifinal ended, Seppi caught the conclusion of Rosol-Nadal. Seppi fell to Rosol in a dead rubber in the Davis Cup in February.

"When he got into the rhythm, especially on the serve, it was impossible to break him," Seppi, the world No. 26, told ESPN.com. "I saw his last three service games yesterday, and it was pretty much the same. He served two or three aces per game; it's tough for the opponent.

"When his game is working 100 percent, he's a very dangerous player, serving big and with some hard groundstrokes. He has to be a bit more consistent, but he has the game to be a good player for sure."

Even if the match Saturday isn't on Centre Court, there still will be many observers when Rosol plays Kohlschreiber.
