Francesco Molinari / Getty Images On a wet and cold second day at Wentworth Francesco Molinari leads the BMW PGA Championship by just one shot after his second round of -4 under par, for a tournament total of -6 under par. Francesco is happy to be at t he top, but is under no illusions as to how hard it will be to stay there on this difficult West course; " I'm really happy with yesterday and today. The conditions were quite tough but I hit the ball well and the putter is working well so I am really happy at the moment. Six under is a good score given the conditions, I live over here now so I am used to it, and I'm in a great position going into the weekend, but it's a really tough course so anyone six or seven behind is still in it." Tied in second place is George Coetzee, at -5 under par, the South African has fared better than his compatriot James Kingston, who topped the leaderboard yesterday but collapsed today with a second round 77. Ten shots worse than his 66 of yesterday, he now has a tournament total of -1 under par. Joining George at -5 under par are Alejandro Cañizares, Marc Warren and Mark Foster. Lee Westwood is lurking at -3 under par and thinks he could be dangerous if his short game keeps improving, and his long game comes together; " My short game's been red-hot. I played some nice pitches and walking off the back of the 12th green, where I pitched to about four feet, Ernie said 'Bit of a short-game wizard now.' I also got up and down on 18 after hitting it in the hazard and those sorts of things can make a big difference to your week and going into the weekend with momentum. If my long game starts to come together, I could be dangerous." Lee's Ryder Cup team-mate Luke Donald made a premature exit in his bid for a hat-trick of titles and fellow heroes of the Miracle at Medinah also made an early departure from The European Tour's Flagship Event, with Rory McIlroy (75), Graeme McDowell (75), Ian Poulter (76) and Paul Lawrie (72) all joining Luke in missing the halfway cut.
