Keeping top spot on the leaderboard from the first round, Mardan shot under-par each round - the only player to achieve this throughout the tournament.
He finished in an 8-under par 280, leading by five shots from second place Mo Joong-kyung of Korea.
When Mardan holed the winning putt on the 72nd hole, he fell on knees and broke into tears.
He gave his gratitude to his wife because she patiently continued to encourage and push him a lot to practice.
