Carlos Sainz Jr. accepted that it was a rookie error which led to him colliding with the bollard at the entry to the pit lane during the Japanese Grand Prix.
Sainz was running in the top 10 but clipped the bollard and damaged his front wing, prompting a slow stop which cost him vital time.
Sainz was able to claim the final point for 10th position, though finished behind Toro Rosso team-mate Max Verstappen.
"It was a good race until the mistake in the pit entry and I even think it was being one of my best races so far this year," he said.
"It was a good first stint on the Options and an even better one on the Primes, I was really flying, catching the cars in front. Then it got to the point that it was simply impossible to overtake the Lotus on track, so we decided to go for the undercut.
"The team told me to do the opposite to [Pastor] Maldonado, and it looked like he was going to pit so I was meant to stay out on track, but he suddenly continued on track and I was so aggressive on the turn into the pit entry that I hit the bollard and damaged my front wing.
"I therefore lost some time during the pit-stop and if it was already meant to be a final long stint, it became an even longer one behind [Sergio] Perez, who was slow in the corners but fast on the straights.
"I destroyed my tyres behind him and in the end it was all about making sure I brought the car back home. The team did a very good job and I’m sure that we would’ve finished higher than P10 if it hadn’t been for my mistake – a rookie error that I will learn from."
