Valtteri Bottas' difficult Australian Grand Prix weekend has been compounded by a five-place grid penalty for a gearbox change on his Williams overnight.
The Finn was already on the back foot coming into the 2016 Formula 1 World Championship opener after a disappointing qualifying session left him down in 11th place, well behind his sixth place team-mate Felipe Massa.
However, a problem was diagnosed with his FW38's gearbox overnight, necessitating a change that has landed him a drop of five places on the grid, leaving him 16th.
As a result, Fernando Alonso and Jenson Button rise to 11th and 12th, with Jolyon Palmer, Kevin Magnussen and Marcus Ericsson each ascending to 13th, 14th and 15th respectively.
Bottas is the second driver of the weekend to land a grid penalty, with Manor's Rio Haryanto demoted three spots for his pit-lane clash with Romain Grosjean in FP3. He drops from 21st to 22nd and last.
