Oscar Piastri said on Tuesday that he would not be driving for Alpine in the upcoming season, only hours after the Formula One team elevated the Australian backup driver to take Fernando Alonso's position.

The club was taken aback when Alonso announced to Alpine that he would move to Aston Martin for the next season. The promotion of Alpine's 21-year-old rising star to compete alongside Esteban Ocon in 2023 was announced after just one day.

However, the Melbourne native claimed that wouldn't happen.

I am aware that Alpine F1 announced late this afternoon, without my consent, that I will be racing for them in 2019. that was incorrect, and I have not entered into an agreement with Alpine for 2023. I won't be driving for Alpine the following season," he tweeted.

This issue is reminiscent of the ongoing Chip Ganassi Racing, Alex Palou, and McLaren Racing IndyCar contract dispute.

Piastri's remarks were absent from Alpine's news release. There have been rumours that the F2 champion was negotiating a better deal with another club at the time.

Piastri is "a bright and uncommon talent" who is "more than capable of taking the step up to Formula 1," according to Alpine's team principal Otmar Szafnauer.

Alonso, a two-time world champion, was hired by Aston Martin on Monday to take Sebastian Vettel's position after the German driver announced his retirement last week. The deal Alonso had with Alpine was set to expire this year.

Six hectic days have been a part of the Formula One "silly season," which began with Sebastian Vettel's announcement that he would be retiring at the end of the current season. 

Alpine asserted that Alonso had not given the team any indication that he would be leaving as late as Sunday night after the race when the Piastri promotion became widely known.

Meanwhile, Williams announced that American driver Logan Sargeant will make his At American Grand Prix later this year, making his F1 debut during the first practice session. The last American to compete in an F1 weekend was Alexander Rossi in 2015. Florida-based Sargeant, an F2 driver at the moment, will be the next.

To "prepare him for the next great step" into Formula One, Alpine said Piastri had already undergone "an intensive and thorough training program" this year.

Szafnauer claims that he has gained the maturity, potential, and speed necessary to be promoted to the team's second seat next to Esteban while serving as our reserve driver at the factory, on the track, and during testing. We believe the two will give us the consistency required to pursue winning as our long-term goal and in the competition.
