For the Williams F1 team the final practice session for the 2013 Bahrain Grand Prix would see Valtteri Bottas finish ahead of team-mate Pastor Maldonado with the pair fifteenth and seventeenth.

The top ten was Vettel from Rosberg, Webber, Raikkonen, Alonso, Di Resta, Hamilton, Massa, Sutil, and Button tenth. So neither Williams would make it into the final period but it was encouraging to see Valtteri perform better than his experienced team-mate Pastor.

The final period would commence without either Williams present with five drivers coming out including Alonso, Rosberg, Hamilton, and Sutil. A 1m:33.388 from Di Resta but Rosberg would set a 1m:32.543 to move ahead. Sutil had come out on the hard tyre and returned to his pit without setting a time. Alonso was second with a 1m:32.667 with Hamilton now third as drivers started to return to their pits,. Webber would come out for his first run running on a used set of medium tyres. Massa was out on the hard tyre indicating a different strategy to team-mate Alonso.

All ten drivers were on the track with both Force India cars on mediums with Button last out. Webber's lap was untidy and he would finish only in fourth with a 1m:33.078. Rosberg was fastest in sector two with Di Resta fifth as Rosberg finish his lap with a 1m:32.330 with Vettel second with a 1m:32.548. Alonso would pit remaining in third from Hamilton, Webber, Massa, Di Resta, Sutil, Raikkonen, and Button. Button would pit without having set a time. But Hamilton would receive a five grid place penalty for a gearbox change while Webber would have to take a three place penalty so Sunday's grid will be somewhat different.

A surprising result with Rosberg on pole but seeing the Williams pair in fifteenth and seventeenth was no surprise at all. Sunday's race in going to be a difficult time for the Williams team.
