Williamsburg, VA (AHN) - The diminutive Mi Hyun Kim may be small in physical stature, but her heart and determination are as big as any professional athlete's anywhere.

After the barely five-foot tall Kim won last week's SemGroup Championship in storm ravaged Oklahoma, she decided to donate half of her winnings ($100,000) to the victims of last week's powerful tornado in nearby Greensburg, Kan.

"Honestly, I make a lot of money in the USA," Kim said Tuesday at the Michelob Ultra Open at the Kingsmill Resort and Spa. "Mostly, I have made donations in Korea. But I wanted to help here, too."

Kim, who averages 240 yards off the tee, said that when she arrived at last week's tournament, she had no plans on winning the course at Cedar Ridge Country Club which covers more than 6,600 yards but played even longer because of torrential rains in the area.

"I never expected to win," the 30-year-old Kim said. "I thought a long hitter would win. Last week was a surprise for me because I am not a long hitter. God gave it to me as a special present. He used me to help those people."

The tornado in Greensburg last Friday killed 10 people and demolished 95 percent of the town.

Though Kim has never even been to the state of Kansas, her huge heart didn't let her think twice about helping others in need.

"The win was a surprise for me," Kim said. "I think God gave it to me like a special present. ... So that's why I want to try to help people."

Kim's victory was her eighth on the LPGA tour and increased her career earnings to nearly $7 million.

Kim is currently ranked 16th in the most recent world rankings and is among the favorites in this week's LPGA tournament at Kingsmill.

Kim's donation will reach tornado victims via the United Way Greensburg Disaster Fund.
