Jeev Milkha Singh carded a one-under 71 in the final round to finish tied 14th at the 120 million
Yen Coca Cola Tokai Classic at the par-72 Miyoshi Country Club West Golf Course in Tokyo on Sunday.
It was a disappointing result for the Indian after having led on the first day and being tied second at midway stage.
Young Eun Yang played some brilliant golf with a five-under 67 on the final day to grab the title, which was the third in his career. It also took him to tenth place on the Money List in Japan.
Jeev, who had a flurry of birdies on first day, had just two on final day on the second and ninth and he also dropped a shot on 13th.
He took 30 putts but struggled on the fairways. However, to his credit, Jeev played on for three days despite being hit with flu.
