Kimi Raikkonen led a Ferrari one-two to outpace Mercedes in second practice at the Chinese GP and suggest F1s world champions could have a fight on their hands this weekend. Having warned that their Italian rivals have not yet shown their full potential in 2016, Mercedes lost out to Ferrari on the supersoft tyre runs mid-way through the session by two tenths of a second.After matching his best finish for three years in Bahrain, Raikkonen ended the opening day in Shanghai on top with his 1:36.896 time one tenth of a second quicker than team-mate Sebastian Vettel. Mercedes completed their qualy-style, supersoft tyre runs slightly earlier and Nico Rosberg and Lewis Hamilton wound up third and fourth respectively. Hamilton, who will start Sundays race no higher than sixth owing to a gearbox change penalty, was two tenths adrift of his championship-leading team-mate, who had earlier topped P1.Its tantalising to see if Ferrari can actually get up there in terms of performance, said Sky Sports F1s Ted Kravitz. David Croft and Paul Di Resta take you through all the headlines from Fridays Practice; and theres interviews with Massa, Vettel and Raikkonen But still the reliability question hangs over them. As we understand it, they do understand the reasons for Sebastian Vettels failure in Bahrain and they are sure that particular problem wont happen again.Vettel, who did not take the start in Bahrain after a valve failure, expressed hope Ferrari could move to within striking range of Mercedes in qualifying: It depends what the others are doing, but I think if we get everything right we could be closer. But then it is only Friday today so I wouldnt stress, I wouldnt put too much importance in the times today. Whens the Chinese GP on Sky?

He has three goals and five assists through 36 games with the Leafs this season. RIO DE JANEIRO -- David Rudisha glanced to his left twice as he came round the final bend, waiting for the challenge to come. It didnt. He didnt let it.The world-record holder surged across the line to retain his Olympic title in the 800 meters on Monday, giving no one else a chance and becoming the first man in more than half a century to win back-to-back titles over two laps at the Summer Games.Rudisha won in 1 minute, 42.15 seconds from Algerias Taoufik Makhloufi, who ran a national record time of 1:42.61 to add an 800 silver here to his gold in the 1,500 at the last Olympics. Clayton Murphy powered through in the final 50 meters for bronze and a PB of 1:42.93, overhauling Frances Pierre-Ambroise Bosse to make the podium.That was the first medal in the 800 for the United States since Johnny Gray in 1992.Rudisha smiled at the end, a broad, beaming smile, relieved maybe after a trying season where he lost a couple of times in the Diamond League and was beaten into third -- third! -- at the Kenyan trials. He freely offered up hugs to the other medalists, too, as he draped the red, black and green Kenyan flag across his shoulders once again.His legacy as one of the greatest 800 runners was pretty firm already, but he cemented it in Rio de Janeiro: The 27-year-old Rudisha has now won four of the last five major titles and the only one missing -- the 2013 worlds -- he was injured for.With no strong challenger coming at him -- not in this race and not in any general sense, either -- Rudisha has the potential to make history with a third straight gold in four years in Tokyo.ddddddddddddHe wants to be the best, he is the best at it, he knows hes the best, said American Boris Berian, who was eighth. Its that confidence right there. He takes it out and he has that confidence to hold on.This was unlikely to be like Rudishas once-in-a-lifetime run at the London Olympics four years ago, when he broke the world record in a wire-to-wire victory of such pure dominance that it was rated as a run for the ages.Heavy rain in Rio a little earlier Monday night also left Rudisha and the others with a damp track at the Olympic Stadium, and the Kenyan does not like running in the wet.He dealt with it and more, though, taking the lead from a fast-starting Alfred Kipketer, his teammate, on the back straight, building a cushion, and then never looking like he was going to be caught. His two quick looks to the left let him know that he had it.Richard Snell of New Zealand was the last man to retain his Olympic title in the 800, at the 1964 Tokyo Olympics.Some formidable 800 runners, including current IAAF President Sebastian Coe, didnt even win one Olympic title in the event. Coe, an Olympic champion at 1,500, consistently says that Rudisha is one of the best athletes the sport has had.For Rudisha, this victory was absolute confirmation, if he needed it, that hes deserving of such praise from former champions.
