Triple world champion Sebastian Vettel set the fastest lap in Spanish Grand Prix practice on Friday with Ferrari's local favourite Fernando Alonso a close second to split the Red Bull drivers.
With sunshine replacing the morning's drizzle, Vettel produced a quickest time of 1:22.808.
Alonso was second, 0.017 slower, with Australian Mark Webber third with a best lap of 1:22.891.
Qualifying has been critical at the Circuit de Catalunya in the past, with 18 of 22 winners there to date starting on pole position and all but one - Michael Schumacher from third in 1996 - from the front row of the grid.
