The former under-24 world time-trial champion, who won Wednesday's 49-km individual time trial, held off the challenge of Tour de France champion Alberto Contador to score his first major victory in a stage race.The 26-year-old Brajkovic is not yet certain to be on his RadioShack team's roster for the Tour, which starts on July 3, but he undoubtedly improved his chances."It's a good thing for me. Let's hope I can do the Tour this year. If not, maybe next year?" he said after crossing the line in the final, 148-km stage.Brajkovic, who has spent almost his entire professional career under the guidance of Armstrong's team director Johan Bruyneel, finished one minute 41 seconds ahead of Spain's Contador overall.Third place went to American Tejay Van Garderen, who finished another minute adrift.Brajkovic, impressive against the clock, also showed real climbing skills in the penultimate stage to l'Alpe d'Huez, yet he said he had not yet reached his full potential."I was lucky today because Alberto did not attack me. I guess he did not want to risk a crash in the downhills so it was great for us."Don't forget Contador did not come here in his best shape but to prepare for the Tour," he said.The final stage ended with five laps of a bumpy circuit with a tricky descent and the favorites took no chances.By contrast, Norway's Edvald Boasson-Hagen, arguably the peloton's greatest prospect, made a bold move in the last lap to win the stage on his own, ahead of Spain's Arkaitz Duran and Russia's Egor Silin.At 23, Boasson-Hagen already has an impressive record of victories with three Norwegian titles, the Ghent-Wevelgem classic and a Giro d'Italia stage."As the Team Sky leader I had to prove myself. I'm really happy I made it. It was risky but I was feeling confident in the descent," he said.
