After all four players parred the par-5 18th, Choi knocked in a 3-footer for birdie on the par-5 17th hole to earn her third career LPGA victory.
“I was nervous, but I tried to focus on my game, so now I’m really happy,” said Choi, who also won the Samsung World Championship and the Hana Bank – KOLON Championship in 2009. “I’m really proud of the way I controlled my emotions today. I think it’s really special to have won wire-to-wire.”
