• 21-year-old claims $5m in one week after brilliant play
• Prize is largest in history of women’s golf

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. And another eagle-birdie finish – for the second straight day – made it happen.

Thitikul claimed the record-setting $4m purse by winning the CME Group Tour Championship on Sunday. It’s the biggest money prize in women’s golf history, bigger than even the winner’s shares in three of the four men’s major championships this year.
