INDIANAPOLIS -- Helio Castroneves held off a dramatic, late challenge from teammate Ryan Briscoe Saturday to claim the pole for the 93rd running on the Indianapolis 500.

Briscoe, who was the provisional polesitter earlier in the day, decided to throw out his second-place spot to take another run at Castroneves about 10 minutes before qualifying concluded for the day.

While Briscoe again fell short to Castroneves, he retained the second slot.

Castroneves got his four-lap average of 224.864 mph at about 4:30 p.m. Briscoe qualified at 224.131 mph.

It's the third time that Castroneves, a two-time winner of the Indianapolis 500, has been on the pole at Indy.

Castroneves accepted a $100,000 check for claiming pole position. He came back to the Indy Car circuit last month after he was acquitted of tax evasion charges.

Former 500 champion Scott Dixon, Tony Kanaan, Marco Andretti and Graham Rahal, also took shots at knocking Castroneves off the top spot without success.

"This place is magic," said Castroneves, a two-time Indy winner. "It's just amazing. ... We just had to keep working through the weather, working through the day. Ryan and I were really strong. When he went out there at the end, I was thinking I didn't really want to have to go out (again).

"Today was about finding the edge. The first attempt was a little easy. That means you're not going fast enough. We worked a little bit and made it a little bit tougher."

Asked if this was even more special because of the uncertainty he faced at the trial in Miami.

"Being here is already being special," Castroneves said. "Many times during the trial I was thinking about it. I was just wishing I would be here."

Castroneves, who previously won poles here in 2003 and 2007, gave boss Roger Penske a record 15th Indy pole. But The Captain was just happy for the driver, who he strongly supported throughout his six-month legal ordeal.

"There's no question the emotion around him," Penske said. "He's one of the most electric guys in racing and everybody likes him. And the good news is he puts the numbers on the board. He doesn't say it, he does it with his foot."

Penske was also proud of Briscoe, who made the decision to withdraw a 224.131 run from earlier in the day and try to take the pole from Castroneves in the final 10 minutes of the session.

"That was a call that Ryan made," Penske said. "He wanted to go for it. I've got enough confidence in him that he isn't going to make a mistake out there."

Briscoe, who qualified a little slower on the second attempt at 224.083, said he might have had a better chance to knock his teammate off the pole if the decision had been made sooner.

"When you get down to it, it's all about timing," the Australian driver said. "We really wanted to do another practice run and then everybody got in (the qualifying) line and we had to get in line. We ran out of time.

"From that standpoint, it's unfortunate, knowing you've got the equipment to get the pole."

It was a big day for Penske, who also placed Will Power, his third driver, ninth among the 11 drivers who locked up starting spots in the 33-car race field.

"Three in nine is pretty good," said Penske, who also has a record 14 Indy wins. "We've just got to be sure we've got one of those in the Winner's Circle on race day."

With wind gusts up to 25 mph making the famed Brickyard oval more treacherous than normal and each entry allowed up to three qualifying attempts, many of the teams were trying to outguess the gusts.

Dario Franchitti, the 2007 Indy winner, waited until after an early flurry of qualifiers in the windiest part of the day and posted a speed of 224.010 that wound up being good enough for third on the grid.

"That wind is horrible," said the Scot, who chose to sit on that speed and not make another try. "It was very, very challenging conditions. The four laps, it was very, very difficult to keep the balance."

Franchitti's effort bumped Castroneves to the outside of the front row and the Penske team quickly prepared Castroneves' car for his fast effort.

Rahal, the son of 1986 Indy winner Bobby Rahal, flirted with the front row, but wound up fourth at 223.954.

The youngster was followed by Dixon at 223.867, Kanaan at 223.612, Mario Moraes at 223.331, Andretti at 223.114, Power at 223.028, Danica Patrick at 222.882 and Alex Lloyd, who barely made it into the first-day lineup in the last five minutes at 222.622, bumping Hideki Mutoh's 222.470.

Mutoh, who qualified earlier at 221.680, was bumped from the top 11 twice, while Raphael Matos, Ed Carpenter and Paul Tracy, making his first Indy appearance since losing in a controversial finish with Castroneves in 2003, were also bumped late in the session.

All of them will have another opportunity on Sunday when the next 11 spots in the lineup are filled. The other 11 positions will be filled next Saturday, with next Sunday reserved for drivers attempting to bump the slowest qualifiers out of the field.
