Lewis Hamilton has gone fastest for Ferrari in final practice for the US Grand Prix after teammate Charles Leclerc led the first two sessions at Austin's Circuit of the Americas.
The seven-time world champion had trailed Leclerc on Friday, complaining about the bumps and the set-up direction of his upgraded car, but he seemed to have got it back to what he wanted in Saturday's final practice before qualifying.
The 41-year-old's best lap was one minute 34.893 seconds, 0.168 quicker than Red Bull rival Max Verstappen and 0.234 faster than Leclerc, to complete the Ferrari practice sweep.
"Ferrari looks to be very strong. They have some nice upgrades, and Red Bull. It looks to me like Ferrari might be the team to beat this weekend," said McLaren boss Zak Brown.
Leclerc would have been top, had he not had his best lap deleted for exceeding track limits at turn nine, while Hamilton also had to take evasive action on a late fast lap to avoid Gabriel Bortoleto's slow Audi ahead of him.
Mercedes' championship leader Kimi Antonelli, who can take the title on Sunday if he wins and other results go his way, was fifth fastest -- also losing a lap time due to track limits -- with closest rival and teammate George Russell fourth.
McLaren's Oscar Piastri was sixth fastest, with teammate and reigning champion Lando Norris eighth. Audi's Nico Hulkenberg was sandwiched between the pair in seventh
Antonelli leads Russell by 102 points with five races remaining after Austin, unless the last two in the Middle East have to be cancelled due to conflict in the region.
Four-time world champion Verstappen has won the last two races in Malaysia and Singapore and was also the winner from pole in Austin last season.
