Adam Scott admits it'll be an odd feeling not having accomplished caddie Steve Williams on the bag at the Masters for the first time in three years.
But 2013 Masters champion Scott has backed current bagman David Clark to pick up exactly where the Kiwi left off.
After helping Tiger Woods to 13 of his 14 major championship wins, Williams famously teamed up with Scott to deliver Australia's first green jacket.
Wellington native Williams was also a part of Scott's rise to world No.1 the following year.
But the pair split permanently before last year's US PGA Championship due to Williams' inability to caddie fulltime.
On the eve of the 2018 majors season, Scott has challenged himself and his regular US PGA Tour caddie to step up.
"It's going to be different not having Steve Williams standing next to me, who obviously has an incredible comfort and knowledge of Augusta," Scott told AAP.
"But I do, too ... that's where I really have to take ownership of how I play and manage golf courses.
"David has a lot on his shoulders now because he has got to perform full-time; there's no hop on, hop off or hiding behind Steve.
"Hopefully, some consistency between us and hard work will amount to success."
Aside from the 2015 Masters, when he briefly retired, Williams was on Scott's bag for every major between the 2011 US Open and last year's British Open.
In addition to the 2013 Masters title, their incredible partnership delivered a runner-up, four top-fives and five top 10s on golf's biggest stage.
"I had a luxury with Steve at big events where he's had so much success in the past, as a fall-back if I wasn't sharp," Scott said.
"Now, I've got to be sharp and hopefully that will rub off on David, so he will learn quickly and we will be on the same page."
Clark is no stranger to Augusta National, having caddied there for former Masters champion Vijay Singh.
"We've worked together a lot; and I'm not trying to turn him into the wizard of Augusta," Scott said.
"It's been a few years, but he's been there as a caddie many times with Vijay.
"He is certainly familiar, but I just want him to familiar with how I like to play (Augusta)."
