Lando Norris narrowly topped the final practice at the Mexico City Grand Prix, beating Kimi Antonelli by just 0.001 seconds as three different teams filled the top three places.
After the strong Friday showing from Ferrari, it was McLaren's turn to lead the way, as Norris set a time of 1:17.600, with Antonelli second and Charles Leclerc third.
Oscar Piastri, who struggled yesterday was fourth, Max Verstappen in fifth and Lewis Hamilton in sixth. In seventh was George Russell, just over half a second slower than his teammate while Isack Hadjar, Liam Lawson and Arvid Lindblad rounded off the remaining top ten places.
The session also marked a change in the Haas garage. Reserve driver Ryo Hirakawa took Esteban Ocon's place for the remainder of the event after the team confirmed the change just before the session started. Hirakawa, who had already driven in FP1 on Friday, was the first driver out on track.
It was a relatively quiet start to the hour, with Alpine, Haas and Cadillac among the first teams to send their cars out. The leading teams took their time before joining them.
Around 15 minutes into the session, the Mercedes pair of Antonelli and George Russell joined McLaren's Norris and Oscar Piastri on track. The four drivers showed strong pace on medium tyres, while Ferrari, like yesterday, looked competitive in the opening exchanges.
Lewis Hamilton, who lost valuable track time after his Ferrari stopped during FP2, briefly moved to the top of the timesheets during the early medium tyre runs.
However, the low-grip conditions continued to catch drivers out. Leclerc, Fernando Alonso and Norris all had their off moments, with several drivers sliding around and pushing the limit while searching for the grip offered by the track.
The conditions made it difficult for drivers to put together clean laps, despite the impressive-looking slides.
Ferrari and Mercedes appeared particularly strong during the first part of the session, while McLaren were still fine-tuning their car.
Red Bull had a less convincing final session. Max Verstappen complained about his brakes on the radio and consistently lost time in sector two. Hadjar was also unhappy, describing the car as "the worst" he had driven all weekend.
The final 18 minutes brought out the soft tyre runs, as teams prepared for qualifying. Russell was among the first to set a representative time on the softs, briefly taking top spot before Norris went quicker. Red Bull struggled on the soft runs, as did Hamilton, who could not keep up with his teammate.
Who are the qualifying favourites
Heading into qualifying, regardless of Red Bull competitiveness, Verstappen is already out of contention for pole due to a one-place grid penalty following his contact with Liam Lawson.
There is no clear favourite between Ferrari, Mercedes and McLaren, as they all appear evenly matched. However, McLaren have grown as the weekend has gone on.
