Scott: Williams will still caddy Masters

Adam Scott has confirmed Steve Williams will be his caddy at next month's US Masters regardless of how many tournaments he wins with David Clark on his bag.

Scott was runner-up in Los Angeles a fortnight ago and a winner at the Honda Classic last week and currently holds a two-shot lead at the halfway mark of the World Golf Championship event at Trump National Doral.

But even if he wins the lucrative event this weekend, and then salutes again at Bayhill or at the WGC Match Play later this month, Scott will bring Williams back for the Augusta National in April.

Williams famously caddied for 13 of Tiger Woods' 14 majors and was on Scott's bag when he broke Australia's duck at the Masters in 2013.

After retiring at the end of 2014, Williams was coaxed back for the last three majors and a handful of other big events last year when a relationship with Mike Kerr didn't pan out for Scott.

Williams and Scott have agreed again to work exclusively in the four majors, leaving the Queenslander to find a bagman for the remainder of his schedule.

Englishman Clark took the job and despite helping Scott back into a rich vein of form, his time at the majors will have to wait.

"The plan is set. David is doing an amazing job and we are working very well together but you could offer Steve the job to any player in the world for Augusta and they are going to want to take him," Scott told AAP.

"His experience is amazing and we work very well together. Loot at our record the last few years."

But Scott was quick to praise Clark, who claimed his first US PGA tour win last week.

"It shouldn't come off as David is second rate in any of this," he said.

"There's lots of good stuff to come and that's why I was so keen to have David.

"When the position was offered he saw the big picture and he was excited and he didn't look at it as though he is getting the shaft by not working the majors and that stood out to me quickly."
