In 2015, Lexi Thompson came from one-stroke back in the final round to defeat 54-hole leaders Lydia Ko and Sung Hyun Park. Thompson carded a final round 69 to win by one stroke at 15-under par, holding off charges on Sunday from Yani Tseng and Suzann Pettersen to win her second event of the season and sixth win of her career. Amy Yang made history with a record nine straight birdies on her back nine during Sunday's final round to tie the course record with a 62 and finish T-4 at 13-under par, two behind Thompson.
