Sepang:Fernando Alonso warded off Sergio Perez's challenge to record an unexpected victory for Ferrari in the rain-affected Formula One Malaysian Grand Prix here Sunday while Sahara Force India secured their first double points finish of the season.

Alonso crossed the chequered flag just 2.2 seconds ahead of Mexican Perez, who ran his Sauber wide with six laps to go, giving the Spaniard a much needed breather.

McLaren's Lewis Hamilton finished third from pole position for the second consecutive time in a race that was stopped after eight laps due to heavy rain at the Sepang International Circuit.

Alonso, who started eighth, took full advantage of the 51-minute break as he took the lead after Jenson Button in the other McLaren contacted HRT's Narain Karthikeyan on lap 15. The incident spoiled Button's race as he completed the 56-lap race in 14th place with the Indian finishing 21st.

Karthikeyan also collided with Red Bull's Sebastian Vettel on lap 48, pushing the reigning World Champion from fourth to 11th position.

Force India's Paul di Resta and Nico Hulkenberg finished seventh and ninth after an ordinary qualifying Saturday when they were 14th and 16th fastest.

The Silverstone-based team would be satisfied with the result considering mid-field rivals Toro Rosso and Williams could only manage either of their cars in the top-10.

While it was a sweet win for Ferrari win after a dreadful start to the season, the Mercedes team struggled through out the eventful race after an impressive qualifying.
