Fernando Alonso is in danger of failing to make the grid for the Indianapolis 500 after setting the 31st fastest time on the first day of qualifying.
The two-time Formula 1 world champion faces a shootout on Sunday with five other drivers for the final three places on the 33-car grid.
If it rains as forecast, the shootout will be when weather allows next week.
Alonso had five attempts at locking in a place in the top 30 on the grid but the McLaren car was not fast enough.
“We didn’t have the speed,” said Alonso, who managed a fastest average over his four-lap run of 227.224mph.
“We are where we deserve today and hopefully tomorrow we will have another chance. If we do not take it, it is because we do not deserve to be in the race.
“The whole week, the speed is not really there in the car. We will not find it in one night. We will try to do a good clean run and hopefully that will put us in the top three positions.”
Fastest of all was American Spencer Pigot, with a speed of 230.083mph, ahead of Australian Will Power. Briton Pippa Mann just made it into the race, one place ahead of Alonso in 30th position.
