HOUSTON -- Simon Pagenaud drew a long breath of humid air after exiting the No. 77 Schmidt Peterson Hamilton Motorsports car following the standing start practice for Race 1 of the Shell and Pennzoil Grand Prix of Houston presented by the Greater Houston Honda Dealers.

"Houston is a track where you don't really have any time to breathe," he said. "There's no straight line. You just go from corner to corner, and the bumps put a beating on you. I'm expecting some surprises and lots of action during both races."

The French driver, who won the inaugural Grand Prix of Indianapolis on May 10, topped the afternoon practice session with a quick lap of 1 minute, 00.1415 seconds on the 1.634-mile, 10-turn temporary street circuit. The three rounds of qualifications, including the Firestone Fast Six to determine the Verizon P1 Award winner, are at 11 a.m. (ET) June 28. The opening 90-lap race of the doubleheader weekend is at 3 p.m. (ET) on NBCSN.

Like the companion 45-minute morning session -- in which Pagenaud was second quick -- five different teams were represented in the top five of the time chart. The top dozen cars were separated by less than a second.

"This car is a pleasure to drive," Pagenaud said. "The track has been improved quite a bit in (repaved) Turn 1, which is quite pleasant. It looks pretty strong right now. We just need to keep up with the track because the car was pretty much perfect today. If we’re good tomorrow on the red Firestone tires, we should be in good shape."

Ryan Briscoe, driving the No. 8 Chip Ganassi Racing car with Plano, Texas-based NTT DATA as the primary sponsor, was second quick (1:00.6428). Luca Filippi, who is making his fifth/sixth Verizon IndyCar Series starts this weekend, was third on the lap chart (1:00.6735) in the No. 16 National Guard car for Rahal Letterman Lanigan Racing. He recorded the quickest race lap in Race 2 at Houston last October.

Drive-ability on the changing surfaces (concrete and asphalt) is a key, according to Filippi, to qualify in the Firestone Fast Six and for a solid race result.

"It would be good to have a car that is fast but, more than all, easy to drive so you can be consistent and drive around the bumps and in the heat; that's going to be tough," said Filippi, who finished 10th in Race 1 and 19th in Race 2 in October in a Bryan Herta Autosport car. "If you can be consistent, it will be important. I like the section (of the track) after the back straight where you have a changing of direction and changes of surface. Where you go from concrete, to tarmac and back to concrete. It's nice and challenging and probably where you can make up the most time from your lap time."

Will Power, who was ninth in the afternoon session and quickest in the morning (1:00.4427), was second overall in the No. 12 Verizon Team Penske car. Power, the championship points leader, won Race 2 last October.

Teammate Helio Castroneves (1:00.6905) was fourth in the afternoon session, while rookie Mikhail Aleshin (1:00.7031) was fifth in the No. 7 SMP Racing car for Schmidt Peterson Motorsports.
