Jenson Button's only hope is rain dance as McLaren racer slides through wet with ease McLaren driver Jenson Button speeds out of the pits as the rain falls during the third practice session. JENSON Button could afford a wry smile as the first rain of the weekend hit Albert Park yesterday. The three-time winner of the Australian Grand Prix knows a wet track is his only chance of adding a fourth title. His new McLaren is a recalcitrant racer that is barely good enough for a mid-pack lap when the track is dry and it's unlikely to be turned around before the lights go out to start the race this evening. So rain could provide an unlikely boost for Button and his new Mexican teammate, Sergio Perez. "The weather conditions are still a bit up in the air with the rain forecast ... and very cold as well," Button said. We could have some surprises with the weather. It will be very hard to get some points but anything could happen," says Perez. McLaren has struggled with its latest car, the MP4-28, since the start of testing. It was quick in the very first laps, but only because the car had - ironically - been assembled incorrectly. We're obviously not quick. The feeling is not good with the car, so we've got a lot of homework," Button said. We have quite a few weaknesses with the car. The ride is a lot worse than we expected. But all is not lost yet. McLaren is also very good in turning things around if times are bad, but it is not as bad as that. Button has often starred in wet races, because his driving style is smooth and consistent, but he will still be battling if he starts deep in the pack. Or if it stays dry. But Perez is not holding out too much hope. "The car is so unpredictable," he said. The car is quite inconsistent through the corners. It's quite difficult to drive and to extract the maximum performance.
