Lewis Hamilton edged out Mercedes teammate Nico Rosberg for top spot in the final practice session for the Russian Grand Prix thanks to a late lap in the 60-minute session.
In a session that saw a number of drivers struggle with the low temperatures and low grip afforded by the Sochi Autodrom circuit, Mercedes once again dominated proceedings as its drivers swept to a one-two finish.
Rosberg and Hamilton exchanged blows throughout the session, having already split top spot in the two sessions on Friday, as Mercedes completed a significant amount of running on the super-soft tire.
Rosberg enjoyed the advantage heading into the final few minutes, running four-tenths of a second clear of Hamilton as the Briton struggled with traffic.
However, Hamilton was able to eke out another late lap with just seconds remaining on the clock, posting a time of 1:36.408 to finish just six-hundredths of a second clear of Rosberg in P1.
Rosberg was left to settle for P2, but Mercedes’ advantage was clear once again as nearest rival Sebastian Vettel finished six-tenths of a second down on Hamilton in P3.
Kimi Raikkonen followed just behind his Ferrari teammate, finishing fourth, while the Williams duo of Felipe Massa and Valtteri Bottas ended the session fifth and sixth.
Max Verstappen and Carlos Sainz Jr. ran well for Toro Rosso to finish seventh and ninth respectively, with McLaren’s Jenson Button splitting the duo as he bids for the team’s first Q3 berth in over a year later in qualifying. Sergio Perez rounded out the top 10 for Force India.
