Daniil Kvyat has said that he still has not sat down to discuss his future in Formula 1 with Dr Helmut Marko.
Earlier, amid great uncertainty about what comes next for the embattled Russian, Kvyat said that he has been promised a meeting with Red Bull kingpin Marko.
Then on Sunday, Kvyat said that he was delighted with his performance in Austin as he returned to the Toro Rosso cockpit in Pierre Gasly's absence.
"It was my best race this year," he said.
"I came here with a new approach to use all the knowledge that I have. I feel I have become stronger psychologically, with a new motivation.
"With a few weeks rest I was able to disconnect and can again feel great potential and used it. I hope I still have the chance to take further advantage of what I have learned.
"Every day I have been asked if I think this weekend is the most important in my career, and if it was, I think I could not have done anything better."
However, Red Bull driver manager Marko says that he will decide between Kvyat, Gasly and Brendon Hartley for the remaining three races of 2017 and then for next year.
Marko seemed happy with Hartley's debut in the US.
"In the long runs he is already very good," said the Austrian. "This is impressive. And his technical statements to the engineers are outstanding."
When asked if he has now had his much-feted meeting with Marko, Kvyat answered: "No, I have not.
"But I do not want to answer questions about this. When I meet, you will know everything."
The season continues in a week's time with the Mexican Grand Prix.
