Danica Patrick put her No. 13 car safely in the Indianapolis 500 field after waiting through a rain delay of 2 hours, 20 minutes.
The first female to lead the race finished with a four-lap average of 227.610 mph, the fifth-fastest of the day and the second fastest after qualifying resumed. She was just behind teammate Simon Pigot, who was fourth overall after 16 qualifying attempts. Ed Carpenter, who owns the team, was scheduled to qualify later.

Just before qualifying began in Indianapolis, series officials announced the IndyCars will be going significantly faster.
Under new rules that will take effect in 2021 and are expected to last through 2026, each car will use a 2.4.liter, twin-turbo charged V-6 engine. Current rules require cars to use a 2.2-liter, twin-turbocharged V-6.
The change will give drivers a boost of about 100 horsepower. When drivers were given a boost of about 50 horsepower for this weekend's qualifying, the top speeds increased by roughly 5 mph.
Testing on the more powerful engines will begin in 2020.
"It's been a long process the last year," IndyCar president of competition and operations Jay Frye said. "The drivers over the last couple of years have talked about horsepower gains, what we need — this will certainly get it to where we need it to be, the plus-900 (horsepower) range."

Only 11 of the 35 drivers made it onto the track following a rain delay of about 20 minutes.
The top 33 drivers will qualify for the starting grid Saturday. All 33 spots will be determined Sunday, including the pole.
