Lap 12, Sainz overtakes Norris ahead to move into fifth, just behind Gasly.
Meanwhile, Vettel is forced to retire at the trackside due to an ERS failure, prompting the deployment of a virtual safety car.
This actually isn't an optimal pit stop window, so no drivers opted for a tire change at this point.
Lap 20, most drivers' pit window is around lap 20, so drivers began to pit for tire changes one after another, and the three DRS trains on the track disbanded during this time.
Qin Miao's window for the medium tires is lap 35, so Qin Miao can continue running comfortably on the track for now.
After the drivers ahead of Qin Miao pitted for tire changes, the track ahead cleared, giving Qin Miao over 6 seconds of clean air to run his own lap times.
Lap 30, Sainz, who was also on mediums like Qin Miao, couldn't hold on any longer on the track, and to prevent an overcut from Qin Miao behind him, Sainz pitted for soft tires.
