for F1 test results [Sunday AM].
Carlos Sainz has topped the final morning of F1 testing at the Circuit de Catalunya in a session curtailed by an accident for McLaren's Fernando Alonso.
Sainz hit the front of the field mid-way through the morning in the Toro Rosso, his benchmark of 1m 25.604secs holding firm to the chequered flag to mirror the efforts of team-mate Max Verstappen at this stage yesterday.
However, as the teams break for lunch, much of the attention is on McLaren once again after Alonso suffered what was described as a big shunt just 15mins before the end of the session.
The Spaniard is understood to have lost the MP4-30 out of the turn three right-hander and going into the inside wall backwards. Tended to by ambulance crews initially, Alonso has been taken to the medical centre, but is reported to be 'OK and conscious'.
Another costly incident for McLaren having lost more time early in the day as it busily attempted to fix the MGU-K seal issue that had truncated its running on Thursday and Saturday, though Alonso eventually got 20 laps in the car before his crash, Jenson Button's hopes of getting into the car this afternoon may now be unlikely.
Elsewhere, Sebastian Vettel lifted his Ferrari up to second place on the timesheets, ahead of Nico Hulkenberg – who made his first appearance of 2015 in last year's Force India – and Nico Rosberg, who recovered quickly after suffering a spin at turn five early on cold tyres.
Alonso was fifth best prior to his accident, ahead of Romain Grosjean in the Lotus, Vatteri Bottas and Felipe Nasr, the latter failing to set a time all morning as Sauber struggle to fix technical problems.
