Logan Sargeant insists that his confidence has not been dented after making a "very costly" mistake at the Formula 1 Spanish Grand Prix.
The Williams driver crashed during Saturday's Free Practice 3 session, triggering the red flags in the process.
While Sargeant was unharmed in the incident, the team were forced into a race against time to ensure that the car was ready for qualifying.
The American started the Grand Prix from the pit lane and eventually finished in 20th and last place.
Reflecting on his performance on Sunday, Sargeant told media, including RacingNews365.com: "I felt like the tyre just went away from me quickly and it was a tough last stint.
"So I just need to understand why [there was a] variation between stints, other than that I was happy with the first two [stints]."
Sargeant: Everything I'm doing needs to keep improving
On whether his tyre management has improved, Sargeant explained: "It's definitely better. It needs to keep improving, for sure.
"But everything I'm doing still needs to keep improving, from qualy to race to everything, so [it's] just part of it.
"The biggest thing is [to] understand why the first two [stints] were good and why the last one wasn't."
Sargeant admits that his error in FP3 also had an impact on the rest of his weekend.
"I think it was a really good build-up on Friday. I think the one mistake [on Saturday] was very, very costly, even heading into qualifying," he added.

Confidence 'absolutely not' affected
Sargeant acknowledges that the crash impacted his lead-up to qualifying.
"[It was costly because] the car had to be rebuilt within two hours, [going] into qualifying and the conditions and everything just sort of led up to a not great qualifying," the 22-year-old said.
When asked if the incident had also proven costly in terms of his confidence, Sargeant denied that this was the case, responding: "Absolutely not."
Despite this, the F1 rookie believes that his weekend could have been more successful without his mistake.
"I think this week was the closest I've been [to extracting the maximum from the car]," Sargeant continued.
"It didn't show in qualifying. That mistake in FP3, having to rush the car build back together, was very, very costly.
"I think, without that, we would have been close to extracting everything."
