LOS ANGELES - Even after her dominant 2011 season, world No 1 Tseng Yani found room for improvement in her golf game that she hopes will pay dividends during the 2012 LPGA season.

The star from Taiwan won 12 titles worldwide last year and seven US LPGA Tour victories.

She is the defending champion at the Australian Women's Open this week at Royal Melbourne where the US LPGA Tour 2012 season officially begins.
