German driver Nico Rosberg on Saturday emerged as the fastest driver in the final practice session for this weekend's Spanish Grand Prix in Barcelona.
Rosberg, who also topped the second practice session, was one tenth of a second faster than Mercedes team mate Lewis Hamilton and Ferrari's Sebastian Vettel, Sport24 reported.
Meanwhile, Max Verstappen finished fourth in his debut for Red Bull after replacing Danill Kvyat in a controversial move last week.
The qualifying for the pole position will be held later in the day.
Rosberg currently holds a 43-point lead over reigning world champion Hamilton in the championship after winning his fourth successive race of the season at the Russian Grand Prix earlier this month.
