After nearly 40 minutes sat in the garage, Leclerc is back out in the Ferrari on some fresh C3s, and he still tops the times having been on the softer tyres earlier this afternoon.
Alonso is back out on the track, this time on a high fuel run in his Aston Martin. Verstappen has pitted so it is just the Spaniard, Piastri, Hulkenberg, Albon and Zhou out right now.
Verstappen hasn't missed a beat getting into the rhythm with the RB20 and is on another longer stint on the C3 compound. Will he and Red Bull fancy a soft tyre run at the end of the day to really flex their muscles?
In the lunch break that wasn't an actual lunch break, Verstappen led the calls for F1 to properly solve the recent track issues that has seen cars sucking up drains and covers.Here's the full story.
"We know that this is a potential problem with these cars, and when you go to certain tracks, you know where the drain covers are."
Russell, still on C3s, improves with a 1m32.163s but remains 11th overall for today. Further back, Zhou also puts in a new personal best for today with a 1m37.179s but is still 19th and not targeting performance running.
And with that, I end my stint for pre-season testing this year and leave you in the capable hands of Haydn Cobb. Will we see any low-fuel runs to end the day? Only time will tell. Over to you Haydn...
Verstappen is now on a long run, lapping around six seconds off the pace and building his lap count which currently stands at a relatively low 18 for the afternoon.
That said, Leclerc sets a personal best first sector and goes purple in the remaining two segments to register a 1m30.322s. He moves 0.4s clear of Verstappen.
Alonso pulls into the pits, and the Aston Martin crew use the opportunity to conduct a practice pitstop. It's great to see how accurate the mechanics are up close and personal, as he gets a swift service before a roll-back into the garage.
There will be a full feature coming later today on the winners of testing. But one of those unlikely to feature in the top category are Sauber. Neither Bottas nor Zhou (currently on the track) have shown pace.
Russell was on a hot lap, going green in the opening sector as the sun sets, but a lock-up at Turn 8 causes him to run wide and bail on the lap. A quick pit stop and he returns to the track.
After two-and-a-half days of mainly long runs and data gathering, it looks like the focus has finally shifted to outright pace. Alonso is the lastest to improve, going third, 0.502s back on Verstappen.
A personal best middle sector and Gasly also goes green in the final sector, with the resulting 1m33.027s moving him to 12th in the Alpine that is sporting additional blue on the nose.
