アンドレア・イアンノーネ
At round six in Catalunya, Hayden retired for the first time this season. Hayden initially had made up ground, where he went from fifth to eighth, to pass the Pramac Ducati of Andrea Iannone, but would crash out of the race on lap six when the front of his machine let go when he turned into the left-hander at turn 10 after passing Stefan Bradl for fifth place.
