George Russell lost his tag of Formula One title favorite to Mercedes teammate Kimi Antonelli on Sunday, but remained confident the momentum would swing back his way.
The Briton had started the season as frontrunner for the championship, and won the opener in Australia, but after three wins in a row for the Italian is now 20 points adrift.
Bookmakers William Hill installed Antonelli, 19, as their 6/5 favorite, with Russell at 9/4.
"Clearly Kimi's in a really great place at the moment and momentum is with him," said Russell, who finished fourth at the Hard Rock Stadium.
"But I've got enough experience myself in championships I've won on how momentum swings throughout a year... To be honest, I'm not even considering it. I just want to get back onto the top step of the podium."
The next race is Canada, where Russell won from pole with fastest lap last year, while Antonelli was third.
Antonelli, at 19 the youngest leader of the Formula One world championship, said he was surprised to be where he is.
"It's still a very long season and there's so many things that can change. George for sure is going to be super strong in Canada," said the Italian.
"But I think I feel much more comfortable in the car, much more in control as well."
