Fernando Alonso has revealed that an overboost on his second lap prevented him pole as he qualified P5 for this Sunday's Indianapolis 500.
After qualifying P7 in Saturday's qualifying session, Alonso was the third driver to take to the track in the 'Fast Nine' on Sunday and put himself on provisional pole with an average speed of 231.300mph.
However, he would gradually slide down to the middle of the second row with Ganassi's Scott Dixon take pole position with a 232.164mph run.
"The car was on the limit," Alonso said. "I don't know if it was possible to be on pole position, but definitely very close.
"I had an overboost problem in lap two out of the last corner, and it was like hitting the brakes. I nearly came to the pit lane because this qualifying run is over with this problem."

There was incident before qualifying that Alonso would have been very used to, with his McLaren-Honda-Andretti car needing an engine change with around 90 minutes left before he was due out on track.
But Alonso was ultimately thankful to his team for the hard work in the garage.
"The practice felt good on the car and then we spotted some issues with the engine," Alonso explained. "At one point in the morning, we didn't know if we were able to run in qualifying because we had to change the whole engine.
"But the team was amazing. They were guys from all six (Andretti) teams working on car (No.) 29 just to make it possible, so thanks to all that teamwork, I was able to go for qualifying."
Thanks for the support today. On the second week we will make more progress and we will keep… https://t.co/w2zez6vao7
