Tracy was fastest at 120.957 miles per hour, covering the 2.25-mile course in 1 minute 7.204 seconds. He scored a valuable point in the championship and has secured at least a front row position in the starting grid.
"We had an off weekend at Elkhart Lake, losing the top spot in the standings, so we had to rebound today," Tracy said. "I know there is a lot of traffic out there but we have to deal with it and get it done."
Tracy also will be looking to record his fifth pole of the season in Saturday's second round qualifying.
Alex Tagliani was second at 120.468 mph and Patrick Carpentier third with a speed of 120.284.
