Denver practice: Haberfeld again

Haberfield lapped the bumpy 1.647-mile street track in 1:00.900s, averaging 97.360 mph. This was more than half a second quicker than his best lap from Friday and was also half a second faster than Bruno Junqueira's provisional pole lap.

"The car is working really well and I'm enjoying this track," Haberfield said. "If we have any kind of luck this afternoon we have the chance to get our best qualifying position so far."

Driving a Reynard for Eric Bachelart's Mi-Jack Conquest team, Haberfield has qualified in the top six only three times this year. The Brazilian Champ Car rookie's best qualifying effort to date was fourth in Germany in May. He also qualified sixth for the season-opener in St Petersburg and was sixth fastest again at Laguna Seca in June.

Second fastest on Saturday morning was championship leader Paul Tracy who was just 0.078s slower than Haberfield. Tracy was second to Haberfield in practice on Friday but slipped to fourth in qualifying. He's hoping to take his sixth pole of the year this afternoon and add another point to his championship lead. Tracy half-spun and clouted a tyre barrier during this morning's session but was able to carry on without damage.

Also impressing in this morning's practice was Tiago Monteiro aboard Fittipaldi/Dingman's Reynard. Montero was consistently among the top ten on Friday and topped the timing charts for a few minutes during Saturday's opening session. The Portguese driver has only made the top ten once this year - at Milwaukee where he qualified ninth - and hopes to produce his best qualifying run of the season later today.

Oriol Servia continued to show good form by turning in the fourth fastest lap this morning followed by Adrian Fernandez and provisional pole-sitter Bruno Junqueira. Mika Salo made some progress this morning, moving up to thirteenth ahead of Montreal pace-setter Alex Tagliani.

Final qualifying takes place later today with everyone running three laps on their own like yesterday.
