Button a special for third win after fastest practice lap

SHANGHAI: With the "double-decker" diffuser of the Brawn car deemed legal by FIA, 2009 F1 championship leader Jenson Button is enjoying being securely back on top of the sport after his second F1 victory at the Australian GP in March followed by a win in Malaysia.

"It's a great feeling (to be back on top), said the Briton, who won his first F1 race in 2006.

"It's not just me, but all of us work so hard for this. If you have a couple of bad seasons, it doesn't mean you have lost passion for the sport and your love for the sport," the Briton said after Friday's practice session.
