British Grand Prix: Pit mistake mars Di Resta's debut
Paul di Resta's British Grand Prix debut was wrecked by two incidents within five minutes as Fernando Alonso grabbed a thrilling win at Silverstone.
Scotsman Di Resta finished 15th despite having impressed in qualifying to start sixth on the grid for Force India.
He was on course for a potential seventh place when his pit crew came out with tyres meant for his team-mate.
Then Sebastien Buemi ran over Di Resta's front wing, forcing the Scot back into the pits for a new nose.
Di Resta, looking for his second top-10 finish in his maiden F1 season, had already lost considerable time as the right tyres were retrieved at that second pit stop.
"I got the call, I came in the pits and unfortunately the wrong set of tyres sitting there," said Di Resta.
"There was a bit of confusion on the team's behalf. There was not much you can do. It can easily happen."
While the Swiss driver had his left-rear tyre shredded in the accident, the Scot carried on but finished four places behind team-mate Adrian Sutil.
"There was no way of getting out of it," Di Resta said of his collision with Buemi.
"He was closing the door. He didn't give me much room.
"He knew I was there, so I think he could've given me a bit much more room.
"I can't honestly say that was going to make a difference to our race."
