Daniel Ricciardo went from the good to worse after two incidents brought him to a premature retirement from the Malaysian Grand Prix.
The Red Bull driver left the garage too early on his fourth stop with his back-left tyre incorrectly installed, and soon after it was his front wing that was damaged by a rumble strip.
Ricciardo's early departure from the pits with the red light still on ended his top five hopes, with Lewis Hamilton emphatic win and his teammate Vettel finishing third.
Indeed the Red Bull mechanic team had to push back the car after Ricciardo stopped on the pit lane, to secure the front-left tyre.
It cost the faulty driver nine places, returning to the track in 14th place.
Ricciardo pushed hard to erase his enormous error to at least catch up with the top ten, but things went from bad to worse for the Australian.
A tricky white and red edge at the end of a corner left the driver without words after it broke half of his front-wing, asking his team "what should I do".
The broken wing damaged the front-right tyre that forced another pit stop, his fifth one of the race.
Ricciardo, frustrated, was retired soon after with four laps remaining.
Hamilton claimed his first victory in Malaysia after eight attempts and his teammate Rosberg finished second just behind.
McLaren's Kevin Magnussen finished ninth separated from his teammate Jenson Button, sixth, by William's duo Felipe Massa (7th) ahead of teammate Valtteri Bottas, and Toro Rosso's Daniil Kvyat tenth.
