Reunited with the Kiwi caddie who helped him win the 2013 Masters, Adam Scott feels confident he can don a second green jacket with Steve Williams on the bag at Augusta National.

Wellington-based Williams, who also caddied for Tiger Woods during 13 of his 14 major championship victories, linked up with world No.7 Scott for the first time in 2017 at last week's Shell Houston Open.

The Queenslander missed the cut before the duo headed to Augusta, Georgia to begin preparation for the Masters starting Thursday (Friday NZT).

Semi-retired Williams now works part-time for Scott, who plans to play the tournament before each of golf's four big dances this year - a move Scott hopes will enhance their chemistry.

The 36-year-old Scott feels he has an edge over the field at the eight events Williams is set to caddie this season.

"These (majors) are the important tournaments and I still feel it's an advantage to have Steve caddie for me. He's very alert and watches what I'm comfortable with and what I'm not," Scott told AAP.

Scott carded a second-round of five-over-par 77 to miss the weekend at Houston, but the silver lining was sneaking in an extra day's preparation at Augusta.

That meant a valuable Sunday practice round at Augusta, which Scott shared with fellow Australian and amateur world No.1 Curtis Luck.

After their first week together since December, Scott feels he's starting to get in sync with 53-year-old Williams.

"We're pretty much in the groove looking forward very much to this week," said Scott.

""I certainly I wasn't firing on all cylinders in Houston but it was more about getting Steve up to speed with where my game's at, he hasn't seen it since December," said Scott.

From five US PGA Tour events this season, Scott has finished outside the top 15 just once, at the World Golf Championships in Mexico in early March, where a head cold blighted his preparation.

But Scott said a solid ball-striking display during his pre-Masters practice round had him confident of bagging a second career major.

"I played nicely today and the game was looking more like what Steve's used to seeing," said Scott.

"I'm always trying to peak (for Augusta) and hopefully I can start building on this for the next few days of practice and then really start firing from Thursday."
