Down by two shots with two holes to play, Jeeno Thitikul knew exactly what was needed to capture the biggest prize in women’s golf history.

On Sunday at the CME Group Tour Championship, Thitikul poured in a 25-foot putt for eagle on the 17th hole and knocked a 6-iron to 5 feet on the last to clip Angel Yin by one stroke and claim the $4 million prize. The gutsy performance came after she won $1 million earlier this week for claiming the Aon Risk Reward Challenge.
