It was Lin’s first World Superseries final in over two years and he took charge from the second game.
Lin, 30, had to qualify for the Sydney event after his ranking dropped to 104 following a seven-month sabbatical from the sport.
He went into the final ranked 22 and is expected to climb further in the world rankings following his Sydney victory.
