The fourth round at the Spa-Francorchamps was also consistent points-wise. He got second fastest lap of his campaign in the second race, and then in the third race he achieved the best result of his campaign so far, a 2nd place. The fifth round at Misano was forgettable, as he failed to enter the top ten in all three races, with a 17th place, 12th place and a retirement in the final race.
