The young German still picked up a career-best finish when he slotted in ahead of Wilson after allowing Servia's rule-ordered pass, placing second and scoring the first podium finish of his career.
"It was a really tough race for me, especially because I had to start from eleventh," Glock said. "I used a lot of 'push to pass' at the beginning to get Nelson Philippe and Jimmy Vasser. At the end I had two shots left. When I was leading the race, I saw Oriol behind me. I know he will try to get me because he was second and third so many times and he wants to win. That was clear for me. I mean, it's disappointing. In one way it's disappointing, and on the other way it's a great weekend for us, to be on the podium after all the races without luck."
Wilson rounded out the podium for RuSPORT while Bourdais settled for fourth. Wilson earned his second podium finish of the year with the result and his first since his maiden win at Portland, although the Brit does have seven top-five runs this year. Bourdais set the fastest lap of the race and led a race-high 59 laps in widening his margin in the championship chase to 61 points with four races to run. The 2004 series champion finished on the lead lap again and has run all but one of the scheduled laps during the 2005 schedule.
Servia moved up to second in the standings with his win, leapfrogging the star-crossed Tracy who fell to third in the title hunt after his eighth-place finish. Alex Tagliani rounded out the top five in front of his home crowd while PKV Racing team-mates Cristiano da Matta and Jimmy Vasser chased him home, finishing sixth and seventh respectively.
Tracy finished eighth while Allmendinger rebounded from his penalty to take the ninth spot, It was a finish that allowed him to move back into the top five in the season standings however, as he claimed a one-point advantage over Mario Dominguez, who finished tenth on Sunday.
Servia became the sixth different winner in the Champ Car World Series this year and joins Wilson as drivers who have gained their first series victories this year. Glock became the eleventh different driver to finish on the podium this season and takes a commanding lead in the Roshfrans 'Rookie-of-the-Year' standings, 27 points ahead of Ronnie Bremer.
