Sugiarto revealed that ever since he started training under the tutelage of his father, former world champion Icuk Sugiarto, he has received a major boost in confidence.
"I am not in the National team in Indonesia," Sugiarto said following his victory over Lin. "Two months ago I started coaching with my dad. His approach is more physical. Before the match, I spoke to him. He told me 'Believe in yourself and you can beat the best'."
With those words of advice etched in his mind, Sugiarto made his father proud by defeating Lin 21-17, 15-21, 21-17 in a hard-fought contest at the Siri Fort Sports Complex.
Even though Lin was being cheered by a majority of the crowd, Sugiarto refused to let his nerves get the better of him and triumphed over the five-time World Champion in an hour and 18 minutes.
"You know who Lin Dan is. He is a legend in badminton," Sugiarto said. "I had lost to him thrice so I had to come up with my best as I know Lin Dan's game.
"He is a superstar wherever he goes. The crowd was backing him so I had to motivate myself and concentrate point after point. I am happy, this is one of my best wins."
Sugiarto also pointed out that Lin has changed his game plan over the past few years. Instead of relying on speed and power, Sugiarto noted that Lin has become more focused on his accuracy, which made him that much harder to beat.
"I think he has changed his game in the last few years," he said. "His game was more of speed power but he has more accuracy. For me I had to match his accuracy.
"I think at 15-all, Lin Dan lost his concentration. He made a lot of mistakes.
"He is a special player. Sometimes he is at his best and sometimes he doesn't give his best."
