Francesco Bagnaia (Ducati Lenovo) started practice off with grip issues and fell back in the pecking order to P20. After making some changes Bagnaia was able to improve to third but questions are looming as to if the Ducati will be able to bounce back from an issue in qualifying with less time to make adjustments. Bagnaia currently holds a 62 point lead in the championship. A win this weekend is imperative with Jorge Martin (Prima Pramac Racing) and Marco Bezzecchi (Mooney VR46 Racing) knocking on the door.
