McLaren rue failed tyre gamble on day to forget in Canada

MONTREAL, May 24 : McLaren drivers Lando Norris and Oscar Piastri had a race to forget at the Canadian Grand Prix on Sunday with the team's ill-advised tyre selection at the start backfiring and their day unravelling from there.

World champion Norris retired on lap 38 with a gearbox problem and Piastri finished outside the points after crashing into Alex Albon at the Circuit Gilles Villeneuve.

Norris and Piastri started third and fourth on the grid but the team chose intermediates tyres for both cars while most of the field went with slicks in cold and slippery conditions.

The decision briefly looked promising when Norris stormed into the lead but the rain had stopped before the start and both cars were forced into early pitstops as the track dried out.

"Unfortunately for us, it stopped raining as the formation lap started, basically," Piastri told Sky TV.

"So, yeah, just one of those things where had it rained a little bit more, we would have looked like heroes. But it didn't, so we looked like idiots."

Team principal Andrea Stella said the call should be judged based on the information available at the time, rather than just on the outcome.

"The rain stopping pretty much after the five-minute signal, and then the double formation lap handed a clear penalty to starting on inters," he told reporters.

"With the rain lasting for a few more minutes, and the race start happening at the right time, we could have seen a big cut starting on the right tyres."

McLaren's problems continued after the tyre gamble failed. Piastri, trying to recover, locked up and collided with Albon on lap 15, putting the Williams driver out of the race.

"I wasn't trying to overtake him. I just locked up, and that was it," said the apologetic Australian, who
