The 26-year-old will arrive at Augusta National fresh off a breakthrough PGA Tour title and a live hope of joining Adam Scott as the country's only winners of the coveted green jacket.
Lee's booming drives, clutch putts and chipping prowess, combined with his social media presence, have turned the Perth product into a cult hero.
But his iron play approaching greens has hampered his progress, something not missed by Lee or coach Ritchie Smith.
"Players like Min, they've got really good with what they do. But if you see something fail enough there becomes incentive to change it," Smith told AAP.
"We've seen the way he was delivering the club not perform the way he wanted, and he's made a decision, 'Well I don't want that to happen anymore'."
So Lee has started hitting his irons higher - Smith estimates his six-iron now climbs about 15 metres above his old trajectory - to create a ball flight they think is essential for PGA Tour success.
"It's significant; a totally different game and takes a lot of trust," Smith said.
"So I'm really proud of him for having a crack.
"We're hitting it a lot higher, a lot better, a lot straighter.
"But there's still a trust component to doing that when you play in wind, and we're not there yet."
The results show exactly that, Lee sharing the 32-hole lead at The Players Championship last month before falling back in blustery weekend conditions.
He followed that up by winning the Houston Open last Sunday, statistics showing his approach play was the difference when his usually trusty driver let him down.
Last season Lee ranked 139th on Tour for strokes gained on approach (-.213).
He's been in the positive in four of seven tournaments this season and was 15th (.995) in the 156-player Houston field last week.
That's help net him five top-20 finishes this season, Lee quick to reference Smith and his lofty ambitions after the Houston win.
"Historically it's been really bad with approach ... so this is just unheard of for us," Smith said.
"He knows he's probably playing the best he's ever played.
"There's just a lag between knowing you're doing really well, but also trusting it because of your history of underperformance of a certain skill."
There will be fanfare on Lee's arrival at the Masters, now the top-ranked Australian and one of five - Scott, Jason Day, Cam Davis and Cameron Smith will all fancy their chances - in the field from Thursday.
Heavy rain and thunderstorms have hammered the region and are expected to disrupt Monday's first practice rounds, before clearing ahead of the first round.
Lee will carry new-found belief along with the inherent confidence he showed when closing with a record-equalling, front-nine 30 on 2022 debut.
"Yeah, he knows he can win out here," Smith said.
"Min's an artist, not a scientist and it (Augusta) makes you manipulate the ball in all sorts of different directions.
"Major success comes when your errors aren't big.
"At the Masters you know you'll make birdies, you just can't make big errors or compound them by making another one."
