Lewis Hamilton helped Mercedes reassert their authority over Ferrari by leading home team mate Nico Rosberg in a dominant display for the German outfit at the Formula One Chinese Grand Prix on Sunday. The race had a slightly anti-climatic feel to its conclusion as the cars crossed the line behind a safety car but Hamilton controlled events from the front and always looked good value for his 35th career win and record-extending fourth in China. "Great stuff, Lewis, great stuff, stellar weekend mate, it's a full house," Hamilton's engineers told him over the radio after the Briton backed up his practice dominance and pole position with the fastest lap of the race in his win. After stunning Mercedes with a brilliant victory in Malaysia at the end of March, Sebastian Vettel threatened early in his Ferrari but once the cars were fitted with the medium-compound tyres for the final stint, the German's challenge faded. A third podium in as many races since joining from Red Bull was still a great result and he would have been the most relieved when Max Verstappen's engine failure brought out the safety car as his fast-finishing team mate Kimi Raikkonen was looming large in his wing mirrors. Hamilton's second win in three races allowed him to extend his lead at the top of the championship standings, the Briton moving on to 68 points with Vettel on 55 and Rosberg a further four points adrift. Hamilton had aggressively angled his car towards the inside on the grid to cover any attack from fellow front-row occupier Rosberg and once the lights went out, the Briton surged ahead of his team mate on the run to Turn One. Vettel protected third behind the two Mercedes but Raikkonen, who was left ruing another missed opportunity after qualifying sixth, surged past Williams' Felipe Massa and Valtteri Bottas off the line to slot into fourth. STRIKING DISTANCE Although Mercedes were expected to regain their dominant stride in the cooler Chinese conditions, Ferrari kept the Silver Arrows honest for most of the early running when the track was at his hottest and the cars fitted with soft tyres. They lurked within striking distance throughout the opening runs and at one point after the first pit stops, seemed like genuine contenders for a second-straight win with Vettel reeling in the two cars ahead of him. The German closed to within less than two seconds of Rosberg but fell behind after switching to the harder compound tyres as Mercedes shadowed Ferrari's tactics to avoid being outfoxed by the Italians as they had been in Malaysia. Williams, who have been usurped by Ferrari as Mercedes' closest challengers, were unable to keep pace with the Italian cars once Raikkonen passed them on the opening lap as Massa and Bottas claimed fifth and sixth respectively, unable to challenge those ahead and well clear of the chasing pack. Romain Grosjean had a steady drive to claim the first points of the season for Lotus in seventh. Sauber claimed a double points finish with Felipe Nasr claiming eighth and Swede Marcus Ericsson rounding out the top 10, the pair sandwiching Daniel Ricciardo, who endured another frustrating race in his underperforming Red Bull. McLaren continued their early season struggles with Fernando Alonso finishing a lap down in 13th, ahead of Jenson Button, who damaged his front wing while attempting a late race pass on Pastor Maldonado in the other Lotus.
