JEREZ, Spain (AP) -- Nick Heidfeld made a strong case to take over from the injured Robert Kubica at Lotus Renault, posting the fastest time on the third day of Formula One testing.

Heidfeld set a time of 1 minute, 20.361 seconds at the Jerez Circuit in southern Spain.

Ferrari driver Fernando Alonso was 0.132 seconds behind Heidfeld, and Michael Schumacher- the fastest on day two of the test- came in at 1:21.054 for Mercedes.

World champion Sebastian Vettel finished sixth.

Renault is considering Heidfeld as a replacement for Kubica after the Polish driver suffered serious injuries when he crashed during a rally Sunday in Italy.
