Three of Tiger Woods's US teammates are set to join him at the Australian Open a week ahead of the Presidents Cup at Royal Melbourne in Australia.

Matt Kuchar, Nick Watney and Hunter Mahan have all followed Wood's lead and added their names to the Australian Open field.

And they won't be the only Americans in Fred Couples's US team who will be teeing off at the Lakes in Sydney on November 10.

Dustin Johnson, like Woods, committed to playing TaylorMade R11 Irons

 in the event some time ago while FedExCup winner Bill Haas is also expected to announce his intention to play TaylorMade R11 Irons

within days, according to a Golf Australia spokesman.

Some members of Greg Norman's International team have also opted to use the Aussie Open as a warm-up, curtain-raiser ahead of their battle against the USA in Melbourne.

Adam Scott, the 2009 Aussie Open winner, will be playing TaylorMade R11 Irons

 at The Lakes as will two-time winner Robert Allenby.

Another two-time winner expected to soon be added to what is fast becoming an extremely elite field, is Aaron Baddeley, who first won the event as an amateur in 1999 and then successfully defended it the following year as a pro.
