Kiwi golf ace Lydia Ko's new coach is being credited with playing a vital role in the turnaround in form that's brought an end to her title drought.
Amid the raft of changes that have fuelled her critics in recent months, the decision to hire little-known former player Ted Oh to shape her swing was seen as the most baffling of all.
But in the wake of victory, experts can see what he's done to help the 21-year-old back in the winner's circle.
With Monday's (NZT) long-awaited triumph in San Francisco, Ko sent an important message.
"For all the haters! It just says hey, as long as you believe and stay patient and positive you can do it," said Ko following her title triumph in California.
It's a mindset reinforced by her new coach, Oh, who understands the plight of the teenaged star and the often-tricky transition into adulthood.
"He's a great fit for Lydia in a sense that he walked in her shoes as it relates to being a prodigy," said the Golf Channel's Tim Rosaforte.
"He qualified for the US Open at 16, so he knows what it's like to be that young and have so much expected of you."
Behind the scenes, Oh has helped Ko deliver her best performance in years as she secured he first tour win since 2016 at the Lake Merced course.
New Zealand Golf High Performance manager Greg Thorpe visited Ko in January and witnessed the impact her new coach was having by adding a competitive edge to training.
"She was putting herself under pressure," noted Thorpe.
"Ted [Oh] was having little games with her to put her under pressure and I think that's been a part of it."
"If you look at the emotion in her over the last few days it does look different to six months ago. She's enjoying her golf, so I think that shows she's back in that space playing really well."
The other notable difference to Ko's game is her new-found power.
"Ted was really interesting in bringing that out in the way she approached her shots - being more aggressive, put the hammer down and see what that felt like and get used to that in practice and eventually bring it into her on-course play."
It's helped her jump five places in the rankings to 13th.
After months of constant change, Ko and her team might have finally found a winning combination.
