Williams: Barrichello slips out of the points.

Barrichello tried to do half the race on soft tyres but slipped out of the points.

Williams drivers’ lap times throughout the race (in seconds):

This was Sam Michael’s last race with Williams. He said: “I would like to thank everyone on the race team and at the factory for the last 11 years and to wish them all the best for a bright future.”

Rubens Barrichello

Barrichello took 12th on the grid ahead of Maldonado, which made for Williams’s best qualifying performance since Monaco.

The pair swapped places at the start but when the safety car came out Barrichello was yet to make his second stop. He switched to soft tyres in an attempt to reach the end of the race without pitting again.

He inherited tenth as Felipe Massa and Maldonado in front of him pitted. But his tyres began to go off seven laps from home and he was powerless to keep them behind.

Sebastien Buemi also took advantage, leaving Barrichello 13th.

Pastor Maldonado

Maldonado made his second pit stop before the safety car period, and moved back to tenth before pitting for the final time.

That dropped him behind Massa and although he passed his team mate three laps from home, he ended up out of the points in 11th.
