Marc Leishman will partner Adam Scott when Australia defends their World Cup of Golf title at Kingston Heath next month.
With world No.1 Jason Day withdrawing with a back injury, Scott had the choice of partner and opted for Leishman for the two-man team event from November 23-27.
"I can't wait to represent my country back home in Australia," said the US PGA Tour star. "Also, my best to Jason for a quick recovery."
Scott and Day won the World Cup of Golf the last time the event was held in Australia in 2013 before both players rose to the top of the rankings.
But with Day scratching himself from the Australian summer in a bid to overcome the back injury that prematurely ended his US PGA season, Leishman must step in.
Leishman, the world No.53 who lost last year's British Open in a three-man playoff, was paired with Scott when he won his green jacket at The Masters in 2013.
The Victorian was also an International teammate of Scott's at The Presidents Cup in 2013 and in 2015.
Leishman, a winner of six tournaments worldwide, will be making his first World Cup of Golf appearance and is relishing the opportunity to play on a sandbelt course after learning the game on such layouts.
"(Kingston Heath is) probably in the top three, to be honest," said the 2009 US PGA Rookie of the Year.
"Along with Augusta National Golf Club and St Andrews. Kingston Heath is not long, it's a very fun golf course and you can shoot really low there.
"You'll have a lot of wedges in your hand. You have to be really precise."
The 2016 World Cup of Golf will return to a 72-hole, stroke play, two-man team event format. The first and third days of competition will be the foursomes (alternate shot) format and the second and final days are fourball (best ball) play.
Two major championship winners from 2016 in Jimmy Walker and Danny Willett plus 27 Olympians and 18 Ryder Cup players will feature among the 28 teams.
