Indianapolis, IN (My Sportsbook) - Robert Doornbos topped the speed charts on the third day of qualifying Saturday at Indianapolis Motor Speedway, as 11 more drivers filled the 33-car field for the Indianapolis 500.

Doornbos turned in a four-lap average speed of 221.692 m.p.h. to place the rookie driver 23rd (middle of row eight) on the starting grid. The Dutchman made his first and only qualifying attempt for the May 24 race since he crashed twice in last week's practices and missed the first two days of qualifying.

"We took off too much downforce and we crashed," Doornbos said. "We had no spare parts, so I missed the first two qualifying days, and then there is a lot of pressure on these four laps to make the show."

Townsend Bell was second-quickest in qualifying at 221.195 m.p.h. to secure the outside position of row eight (24th).

Oriol Servia, Alex Tagliani and Tomas Scheckter currently make up row nine, while Mike Conway, E.J. Viso and Ryan Hunter-Reay occupy the 10th row. Both Servia and Scheckter secured rides for the Indy 500 earlier this week.

John Andretti and Milka Duno withdrew their first qualifying attempts and made their second runs in the final minutes to claim the 31st and 32nd spots, respectively. Duno bumped Buddy Lazier off the grid and dropped rookie Nelson Philippe to the outside of row 11 for the final spot in the field.

Philippe's average speed of 218.032 m.p.h. has him on the "bubble" heading into Sunday's Bump Day (the final day of qualifying at Indianapolis).

"Today doesn't really mean anything," Philippe said. "We're in it today. The only thing is that if it rains tomorrow, we're looking pretty good."

Rain forced the first 3 1/2 hours of Saturday's six-hour qualifying session to be delayed.

Lazier, Stanton Barrett and Bruno Junqueira, who picked up a ride prior to the start of third-round qualifying, will all attempt to make the field in Bump Day.

Lazier, the 1996 Indy 500 winner, attempted to make a second qualifying attempt, but ran out of time before he could make it on the track.

"I know we had a lot left in the car, and we were going to get another run in, but we just got behind and it was late," Lazier said.

Barrett, also a competitor in the NASCAR Nationwide Series this year, made his second attempt in the closing minutes, but came up short of bumping Philippe off the grid.

"We were just trying some things in the car to help build some speed," Barrett said. "We tried something on the last lap to try and get a little bit more based on what the wind was doing."

One week ago, Helio Castroneves won his third career Indy 500 pole after averaging 224.864 m.p.h. in his qualifying run.
