Indianapolis ? As the minutes ticked away Sunday, the final day of qualifications for next week’s Indianapolis 500, Roberto Moreno and his team took stock of their situation.

With less than an hour to go until the 33-car field was set for the May 27 race, the 48-year-old Brazilian, hoping to drive in his third 500 in 21 years, was “on the bubble,” the slowest qualifier in the lineup at 216.229 mph.

Moreno said he was sure that wasn’t going to be fast enough.

As he became more comfortable in his car Sunday, Moreno’s practice speeds climbed and he knew it was time to get aggressive instead of waiting for a faster car to bump him.

“I saw that I achieved 220 (mph) and was solid in the car and said, ‘OK, guys, that’s enough. Let’s go for it.’ “

Moreno, who took his ride in the No. 77 Chastain Motorsports car on Friday, the day after Stephan Gregoire crashed, fracturing a vertebra, was up to the challenge. His first lap was over 219.8 and the next three were all over 220, giving him an average of 220.299 – more than 4 mph faster than the speed he posted Saturday.

“Yesterday, we were not ready for it,” Moreno said. “We played around too much with the car. I told my engineer to just make me comfortable so I could go flat around this track. I’d never done that. My cars I drove before, I never drove flat here.”

Moreno, who finished 19th in 1986 and 20th in 1999, was so happy with his run on Sunday, he took his hands off the steering wheel before he completed the final lap, raising his arms in triumph and shaking his fists.

Ironically, it turned out his first qualifying speed would have made the lineup anyway. But Moreno didn’t care.

“Now I know I have a good car to race next week,” he said.

Moreno joined Richie Hearn and rookie Phil Giebler as Sunday qualifiers, with Jimmy Kite, who began the day with the slowest speed (214.528) among the 32 drivers already in the lineup, the only driver bumped out.

Hearn, whose last of six previous Indy starts was in 2005, signed Saturday with longtime IndyCar team owner Ron Hemelgarn and co-owner-driver Jon Herb, then had to wait as the Hemelgarn/Racing Professionals team put together Herb’s backup car for him.

The No. 91 Dallara, with no sponsorship on the sidepods, made it out to the pit lane late on Saturday, but Hearn never made it onto the 2.5-mile Indy oval until Sunday morning.

Hearn quickly had the car up to speed in practice. He then filled the 33rd spot in the field with about three hours remaining on the last of four days of time trials for the 91st 500-mile race, posting a speed of 219.860.

He joined teammate Herb, who qualified Saturday after being bumped twice on the opening weekend of time trials, in the lineup. Hearn said he’s confident the car could go a lot faster but didn’t want to waste time and take chances.

“I did a run just before that and did 219s and thought, ‘Why not?’ That was good enough to keep some people behind me,” Hearn said.
