Teenage golfer Yuka Saso's triumph at the U.S. Women's Open was met with jubilation from her Japanese supporters Monday, with her father crying tears of joy as he watched her hoist the trophy.

"I didn't think she would win it this quickly. I'm so happy," Masakazu Saso said as he looked on at San Francisco's Olympic Club after her victory.

Born to a Filipino mother and Japanese father, Saso became only the third woman with Japanese citizenship to win a major title and tied the record for the youngest to win the tournament at 19 years, 11 months, 17 days.
