Raikkonen leads Ferrari one-two in final practice for F1 Spanish GP

After a subdued Friday dominated by Mercedes, Raikkonen posted a 1m20.214s on soft tyres to outpace Ferrari team-mate Sebastian Vettel by 0.242s.

But Vettel's day was not without trouble, as his session came to an early end after stopping in the pitlane with 10 minutes remaining.

Lewis Hamilton, who had topped both of Friday's sessions, had to settle for third place ahead of Mercedes team-mate Valtteri Bottas, who managed just seven laps.

Bottas's day got off to a difficult start as Mercedes worked on his car following an electrical issue that made the team break the curfew.

As a result, the Russian GP winner was then forced to revert to an older-spec engine for the rest of the weekend after a water leak was found. He spent the majority of the session in the garage.

Red Bull duo Max Verstappen and Daniel Ricciardo finished fifth and sixth as the usual order was restored at the front of the field.

Nico Hulkenberg continued to shine in the Renault with the seventh fastest time, ahead of Felipe Massa's Williams and local heroes Carlos Sainz (Toro Rosso) and Fernando Alonso (McLaren).

Alonso, aiming to make up for the lost time on Friday, was the first driver to register a time early on, but was soon demoted by Esteban Ocon in the Force India fitted with medium tyres.

Raikkonen was the first of the frontrunners to complete a timed lap, the Finn posting a 1m22.494s using mediums at the 15-minute mark. Vettel slotted into second a few seconds later.

With 36 minutes to go, Hamilton moved to second with his first run on medium tyres, the Briton over three tenths slower than Raikkonen despite setting the fastest time in the middle sector.

Verstappen only set his first time of the day at the halfway point after a slow start, jumping to third in the medium-shod Red Bull.

He improved his time, but not his position, on the second lap of his run, but was still over six tenths of Raikkonen's pace.

With 22 minutes left on the clock, Raikkonen improved to a 1m20.214s as he ran with Pirelli's soft tyres, opening a gap of over 2.5 seconds to his closest rival before Vettel used the yellow-marked rubber to jump up to second, 0.242s off the pace.

The German had to return to the pits without completing the planned second flyer, however, as Ferrari detected a problem with his car and called him in.

Hamilton's first run on softs with 17 minutes remaining produced the third quickest time, 0.381s behind Raikkonen.

Vettel attempted to return to the track for a final run with 10 minutes remaining when he stopped while driving up the pitlane. After he was dragged back to the garage, the team began working on the car but it did not return to the track.
