BALTIMORE -- Sebastien Bourdais was disappointed with the qualifications effort for the Grand Prix of Baltimore presented by SRT, but showed in the race day warm-up that the No. 7 Dragon Racing car indeed is fast on the 2.04-mile, 12-turn street circuit.

Bourdais topped the time sheet in the 30-minute session, posting 1 minute, 18.4535 seconds on his last of 16 laps. Will Power, who will start on the front row in the No. 12 Verizon Team Penske car, also recorded his fastest time on his final lap (1:18.7543) for second in the session.

Bourdais's car sustained damage in Round 1 of qualifying Aug. 31, which brought out the red flag and deleted his two best lap times.

"I got a little greedy. At the chicane I was trying to get some reference to see how much I could go on the curbs," he said. "I guess I just stepped over the limit. I put the tub on the curb and bounced off of it and the tires were waiting for us at the exit. This busted the car up so its pretty frustrating and disappointing for the guys. We still have a fast car and we will try to move forward during the race and see what we can get."
