The Queenslander was on the practice putting green more than two hours before his 2:35pm tee time spending a significant amount of time hitting putts of various lengths under the watchful eye of coach Brad Malone with an armlock Scotty Cameron putter – a longer putter that runs up the inside of his left forearm, employing his familiar pencil grip.

The armlock Scotty Cameron mallet is not a new putter to the 2013 Masters champion, Scott using the putter earlier in 2019, including at the Farmers Insurance Open at Torrey Pines where he was runner-up to Justin Rose in his best finish of the season.

But Scott switched to a lie angle balance Directed Force putter at The Honda Classic, the change in putter with Augusta and The Masters specifically in mind according to the 38-year-old.

“I’ve used a few different putters this year, this week I’m going to use the Directed Force putter that I used the last two events I have played. And I have really decided on using that with this event in mind. It’s the putter most suited for me to this golf course,” Scott told reporters at Augusta on the Sunday before Masters week.

Scott currently ranks 14th on the PGA Tour in Strokes Gained: Putting for the 2018/19 season, a vast improvement over recent years. And he acknowledged the need to hole more putts over the weekend if he is to claim a second major title when he spoke to the media after his second round 68 in dreary conditions on Friday.

“Hopefully the putter can warm up a little bit. It was good – it was pretty good for two days, but you know, a hot putter will go a long way on the weekend,” Scott said. “But if I can rely on my ball‑striking, then that will take some of the pressure off and maybe free me up a little bit.”

Scott’s Directed Force short putter remained in his bag as he worked on the putting green on Saturday before his round, but the former World No.1 only used the armlock putter during his early practice session before returning to the caddie locker room by the practice area.

If he indeed does make the switch and manages to win Australia's second green jacket on Sunday, Scott wouldn't be the first player to win The Masters with a putter change during the tournament. Nick Faldo making a similar mid-tournament putter switch on his way to victory in 1989.
