Under a cloudy sky that provided cooler conditions for the start of the track action, the two-time MotoGP world champion's 1m56.682s remained the time to beat throughout the day, with several challenges coming up short over a single lap attack.
Opening day pacesetter Jorge Martin came closest to toppling Bagnaia with a 1m56.854s on the Pramac Ducati, while factory Ducati rider and yesterday's timesheet topper Enea Bastianini slipped into third with a 1m56.915s.
Given a sub-1m57s lap had never been seen before today at Sepang in MotoGP, it was remarkable to have four riders inside the time as Gresini Ducati's Alex Marquez joined the fray with a 1m56.938s.
With conditions at the optimum due to cooler temperatures and maximum grip levels after a total of six days of track action including the shakedown, it wasn't surprising to also see the long run pace cranked up too.
Bastianini appeared to have an edge over the sprint race-style runs from Martin, coming in half a second quicker, with Aprilia's Aleix Espargaro over a second further adrift, while rookie sensation Pedro Acosta produced an eye-catching run to put him fourth and quicker than Bagnaia over a nine-lap dash.
Espargaro was the standout rider for Aprilia on the 2024 RS-GP with fifth place on the overall times on a mixed day for the Italian squad, as both Maverick Vinales and Miguel Oliveira struggled to 12th and 18th respectively.
