Denmark duo Soren Kjeldsen and Thorbjorn Olesen carded a stunning 12-under 60 in Friday's four-ball to take a three-shot lead at the World Cup of Golf.
After opening with an even-par 72, the Danish pair had two eagles and eight birdies at Kingston Heath Golf Club in Melbourne.
The eagles came at holes three and eight, either side of a pair of birdies, before a red-hot back nine.
The duo holed five birdies in a row from the 10th and another to finish, giving one-time runners-up Denmark a chance at a first title.

China's Wu Ashun and Li Haotong are second at nine under after producing a 65.

A group of four teams sit a shot behind them, including American pair Rickie Fowler and Jimmy Walker - who produced a 67.
England (Chris Wood and Andy Sullivan) were flawless with a 66, while Italy's Francesco Molinari and Matteo Manassero had just one bogey to be alongside them.
French duo Victor Dubuisson and Romain Langasque are also in the group after a 67.
Australia are defending the title but sit a long way back at two under, despite Adam Scott and Marc Leishman managing a four-under 68.
