After making an unbeaten 105 against a world-class South Africa bowling attack, 20-year-old Cricket Australia XI left-hander Campbell Kellaway explained his philosophy on batting.

"I've watched how the guys at the top level like Steve Smith and Marnus Labuschagne go about it and they have a real appetite for runs," Kellaway told AAP.
