Henderson, playing alongside Lewis, failed to break par for the first time in 11 career competitive rounds at Columbia-Edgewater, dashing the 19-year-old Canadian's bid to become the youngest three-time victor of a tournament in LPGA Tour history.
Stacy Lewis, a 2003 graduate of The Woodlands High School, announced on her Twitter account late Wednesday night her intentions to donate her entire winnings from the LPGA Tour stop this weekend to Hurricane Harvey victims.
"I played the round with a good feel, but I would've liked to improve my score by three at least", said Miyazato, who won the tournament in 2010.
"I have been motivated", said Lewis, who shot a 65 yesterday morning (Singapore time) to take a three- shot lead into this morning's final round of the LPGA Tour's Portland Classic. She won her 12th LPGA title for those suffering from the epic rainfall and deadly flooding that destroyed so many homes and businesses in Houston. She shot a six-under 66 while Thailand's Moriya Jutanugarn (72) and American Brittany Altomare (69) finished in a tie for third. "You have to get a lot of things right, to go your way". "Everybody talks about it", she said.
Gerrod Chadwell, Lewis' husband, is the head coach of Houston's women's golf program and had to deal with Harvey uprooting his team for the time being.
The 32-year-old American looked well on course to be able to hand over the United States dollars 195,000 (£150,000) first prize when she started the day with a three-shot lead over the chasing pack and then birdied the opening two holes.
She said she's looking forward to next week and trying to lock up a victory before the season is through, perhaps even, at the year's final major.
Jutanugarn briefly flirted with the lead after making six birdies on the first 10 holes. Chun missed a short birdie putt at the par-4 14th, and pulled to within a stroke with a 45-foot birdie at the par-3 16th.
Finishing second in tournaments, "sometimes it's your fault, sometimes it's not", she said.
The good that money can do for a displaced population had Lewis pumped up after her win.
Lewis also called on her fellow LPGA Tour pros to grab an extra pair of shoes when they next go shopping and she would hand them over to those in need. "It's nice to see yourself do that again".
