Motor racing: Williams' Bottas quickest in final Austria practice

SPIELBERG, Austria (REUTERS) - Valtteri Bottas of the Williams Formula One team turned in the fastest time in Saturday's final practice for the Austrian Grand Prix, nipping Lewis Hamilton of Mercedes and leaving championship leading Mercedes teammate Nico Rosberg in fifth.

With the sun only occasionally poking through overcast skies, the Finn posted a fast final lap to turn in a best time of 1min 9.848sec, edging out Hamilton by 0.050sec.

Williams team-mate Felipe Massa was third and Daniil Kvyat of Torro Rosso fourth ahead of Rosberg, who was 0.151sec off the pace, as six-tenths of a second covered the top eight drivers.

Sergio Perez of Force India went wide off one turn and saw his car briefly go airborne on Saturday before recovering.

Hamilton had been comfortably quicker than Rosberg in free practice on Friday, when the two Mercedes were the only cars to lap in under 1:10. The Briton is 22 points behind Germany's Rosberg after seven races.

Hamilton has won four races to Rosberg's two so far this season, but has also suffered two costly retirements.

Qualifying for Sunday's Grand Prix, the first in Austria in 11 years, starts at 1200GMT (8pm Singapore time).
