Indianapolis 500 fills 33-car starting grid

British driver Katherine Legge has become the 33rd driver to qualify for next week's Indianapolis 500, assuring race organizers of a full field.

Legge was the ninth driver to make an attempt Sunday, the second and final day of qualifications. She was hired Saturday to drive the No. 81 car for Schmidt Peterson Motorsports.

The only car not on the 11-row starting grid is the No. 17 of Mexico's Michel Jourdain Jr. He is expected to make an attempt to bump his way into the field by knocking out the slowest of the second-day qualifiers. That would be Legge, who had a four-lap average of 223.176 mph.

Qualifying at Indy continues until 6 p.m.

The fastest second-day qualifiers were Americans Josef Newgarden at 225.731 and Graham Rahal at 225.007.
