Suzuki's Alex Rins held off a spirited challenge from Repsol Honda rookie Alex Marquez to claim his first victory of the season at the Aragon Grand Prix in Spain on Sunday.
Rins' team mate Joan Mir finished third to take a six-point lead at the top of the championship ahead of Fabio Quartararo, who started at the top of the grid but finished a disappointing 18th for Petronas Yamaha.
Starting 10th on the grid, Rins stormed out of the blocks to move up to fourth on the opening lap before moving past Yamaha's early pace-setter Maverick Vinales to take the lead on lap eight.
