That’s when the contest really began.
Both girls parred the first extra hole – the par five first – then went to the par-three second, which they played three times, including once when Kath looked out of it, but chipped in for a par.
Fearing the match would never end, officials then sent the girls to the nearby par-four 16th , where both players hit long drives and excellent approach shots.
Yuuki chipped from the fringe of the green to within 2m of the hole, only to watch as Kate sank a marvellous 17m putt for a birdie and the win.
“That was incredible,” Kate said.
“Augusta is a subtle course,” Leigh explained.
“You need to be able to draw the ball, fade it and, sometimes, hit it straight. And the preferred landing area on some holes is very small.
“But deChambeau is a big, powerful man. He gets himself into position, pauses, then goes all out.
“He’s got complete trust in his swing and just goes for it. I like that.
“He’s really well balanced and hits straight through the ball,” Leigh said. Frank Chong (right) congratulates Leigh Lasek on his extraordinary round of 47 stableford points at Maroochy River
He went on to explain that he picked up a tip from watching deChambeau – something about keeping his left arm straight, coming through on a nice plane, and rotating through the swing.
