Teen Kiwi golf sensation Lydia Ko returned to New Zealand as a professional yesterday - and her first engagement was for charity.

Adam Scott took advantage of easier morning conditions yesterday to shoot a 4-under 67 at Royal Pines and take a two-stroke lead after two rounds of the Australian PGA championship.

Elanor Grimwood would one day like to emulate Lydia Ko in bursting on to the international golf scene.
