"I've been motivated for one, but I've just been extremely calm", said Lewis. "I think it's something we should talk about because it's a big deal".
Lewis, 32, won her 12th LPGA Tour title and first since June 2014.
"I knew it would be hard to make it to the top, but I kept myself motivated trying to see how far up (the leaderboard) I could get", Miyazato said.
"I finished without being able to find my rhythm".
"Feel like I played well at Solheim, and last week took the week off just trying to recover". "It was just unbelievable how when you let go of the control like that, how great you can play".
Lewis moved to Houston when she was 11, and her husband, Gerrod Chadwell, is the women's golf coach at the University of Houston.
It appeared that Lewis would lose her advantage when she hit her approach to the par-4 17th over the green while Chun found the putting surface.
"I was fine until he showed up and then I started crying", she said.
"You know, when I said that I had the goal of winning the tournament-you got to get a lot of things right, to go your way", Lewis said. "So just to have him here and get to share the win with him was pretty special". "I have been hitting solid and (gave) myself a lot of really good chances for birdie".
Chun also parred the final two holes in a 66.
Lewis entered Sunday with a three-stroke lead over Moriya Juntanugarn and hung on late to beat In Gee Chun by one. Her career earnings are about $2.4 million, and she was ranked sixth in the world coming to Portland. Chun was another stroke back after a 69. The cut was 1-under par.
Lewis surged into a three-way tie atop the leaderboard with a bogey-free 64 on Friday and continued her blistering play in the third round with birdies on five of the first eight holes. "I just handed over the controls (to God) and said, 'Take me there'".
Chun rolled in a 25-foot birdie putt on the par-3 No. 16 to get to 19-under, one off the pace.
"It was a little up and down today", Henderson told media following her round.
Stacy Lewis will join three other 2017 American winners in the Indy Women in Tech field: Cristie Kerr, Lexi Thompson, and Danielle Kang. I really enjoyed playing with Stacy.
South Korean players' winning streak on the LPGA Tour has ended at five.
"I was pretty happy", said Jutanugarn. "On the last hole, I got really emotional".
Annoucing her pledge "probably made things harder, because there were more people following me, more phone messages and more social media. This is my favorite city forever now". She failed to break par for the first time in 11 career competitive rounds at Columbia Edgewater, all but ending her bid to become the youngest three-time victor of a tournament in tour history.
