Marc Marquez now back on top with a 1m39.385s.
Just under 10 minutes to go in this session. Zarco still fastest.
Bezzecchi still running strong as he moves up to second, while Joan Mir confirms Honda's decent pace this morning in fifth.
Yamaha looking good also in sixth and seventh with Jack Miller and Fabio Quartararo.
In a reverse of Friday in Thailand, Bagnaia looks like he has gotten in the way of Franco Morbidelli on the run into the penultimate corner.
Nothing major, but Bagnaia has bailed into pitlane as team-mate Marc Marquez heads back out.
Bagnaia makes a small improvement to 15th, but is 1.9s off the pace at present. He doesn't look hugely comfortable right now.
Zarco improves to a 1m39.397s. Again, nothing to get too excited about but it's been a long time since we've seen a Honda come out and consistently set session-best laps.
Johann Zarco hits the front again with a 1m39.794s, while Bagnaia has a bit of a front-end twitch exiting Turn 1.
For reference, the best ever lap around Rio Hondo is a 1m37.683s set in 2014 by Marc Marquez.
Marc Marquez gets under the 1m40s barrier for the first time today, setting the benchmark to 1m39.991s.
Alex Marquez now takes over top spot with a 1m40.359s.
Marco Bezzecchi goes fastest now with a 1m40.383s.

Raul Fernandez has become the first crasher of the weekend.
He ran wide at Turn 1 and dropped his Trackhouse Aprilia in the gravel. A slow-speed tip-off but he's back up and running.
Marco Bezzecchi jumps up to second on the Aprilia.
Good track this for the RS-GP, as it was the scene of its first MotoGP victory back in 2022.
Hard to read into anything right now, but this is reasonably encouraging for Honda. A lack of rear grip remains an issue, but in low grip conditions Zarco is looking pretty solid.
The agility of the RC213V should help Honda a lot this weekend.
Zarco goes a bit quicker again to a 1m40.405s, with Maverick Vinales just over a second adrift.
Zarco has improved to a 1m40.887s ahead of KTM's Brad Binder and Pramac Yamaha's Jack Miller.
Bagnaia now the latest to run wide at Turn 1. Team-mate Marc Marquez is now heading out for a look at the circuit.
Pedro Acosta has run wide at Turn 1. This is the first time he's been at Termas de Rio Hondo as a MotoGP rider.
Johann Zarco leads the way after five minutes with a 1m44.741s.
One rider not rushing out just now is championship leader Marc Marquez. He's quite happy to watch his team-mate Pecco Bagnaia explore conditions.
FP1 is go!
Just five minutes till pitlane goes green for FP1.
The 45-minute FP1 session coming up now will largely be an unrepresentative one due to track conditions.
There are some damp patches around after overnight rain, which haven't cleared yet as it's pretty chilly at Termas de Rio Hondo.
Jorge Martin out!
The big news coming into today's practice sessions is the continued absence of MotoGP champion Jorge Martin.
He confirmed on Thursday that he will also miss the upcoming Americas GP.
Practice begins
Good afternoon and welcome to live text coverage of the 2025 Argentina Grand Prix!
FP1 gets underway in 15 minutes.
