Carlos Sainz believes he could have scored points had the tyre gun not failed in his first stop during the Formula 1 70th Anniversary Grand Prix.
The McLaren driver started the Grand Prix from 12th on the grid, and had a strong start, running inside the top ten by the end of the first stint.
But, all of his hard work was undone in the opening pit-stop when he lost time due to a tyre gun failure.
It was then further compounded by Sainz having to stop immediately as he left the pit box to let a passing car through in order to avoid an unsafe release penalty.
The lost time in the pitstop meant that the Spaniard dropped right out of the top ten and he eventually crossed the line in 13th, while team-mate Lando Norris managed to score points with a ninth placed finish.
Speaking after the race, Sainz said: “A disappointing day for all of us. We managed to get a good start and after a very strong and long first stint we were in a good spot.
“Unfortunately, it looks like we had a gun failure in the pit-stop, which undid all the work done before the stop.
“It looks like we could’ve been on for some points today with the tyre strategy we had and with how we managed the race, but again I missed out on a good result for reasons beyond my control.”
McLaren Team Principal Andreas Seidl also added that both cars struggled with the tyres around the Silverstone circuit, and that as a result they were slower than their rivals during the race.
“We had expected a challenging race after having struggled for pace all weekend in the hot ambient conditions.” commented Seidl.
“Finishing P9 with Lando was the best we could do with the performance of the car.
“Carlos was unfortunate to lose the opportunity to join his team-mate in the points, after an equipment failure during his pit-stop.
“Both drivers gave it their all on track; my thanks to them and the entire team for the commitment and hard work they have put in across these two weeks at Silverstone.
“We will reset tomorrow and try to find a better level of performance for Barcelona.”
