The eagle shot on the par 4, 11 hole, was a really tough shot, she added.
"It would be probably one of my most special wins, just to be able to do this for the people in Texas and to do it too when everybody is watching", Lewis told reporters. But a huge par putt from Lewis sent the tourney to the 18th, where Chun missed the green and Lewis hit it from a fairway bunker and made a two-putt par to save her emotional victory.
"I have been motivated", said Lewis. "My caddie (Travis Wilson) has been here way more times than anybody probably in this field, and so I think we have an advantage as far as knowing the golf course". Lewis' husband, Gerrod Chadwell, is the head women's golf coach at the University of Houston.
Chun has four runner-up finishes in 2017 but hasn't yet cracked the winner's circle.
Chun's bogey-free round of six-under 66 at the par-72 Columbia Edgewater Country Club took her to 19-under 269 but wasn't enough to overtake Lewis, who, playing in the same group with Chun, held on with a 69 in the final round.
Lewis, of Toledo, Ohio, carded eight birdies and no bogeys in her round, which she considered one of her best of the year. She won her 12th official LPGA Tour title, her first since June 2014. "I've just needed a couple good breaks here and there", Lewis said.

Stacy Lewis shot an 8-under 64 on Friday for a share of the lead with two-time defending champion Brooke Henderson and first-round leader In Gee Chun at 10-under 134 at tree-lined Columbia Edgewater. She stayed in close contact with Chadwell, who was back at their home.
Lewis entered Sunday with a three-stroke lead over Moriya Juntanugarn and hung on late to beat In Gee Chun by one.
Indeed, it was her second-lowest single round score of the year (she shot a 63 at the Pure Silk Bahamas LPGA Classic in January, the first event of the year). If she finishes second she would earn US$120,000. "It's nice to see yourself do that again".
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.
Ai Miyazato shot a 67 to tie for fifth at 13 under in the Japanese star's final US start. I know Stacy have a little hard time before, so I want to give to her big congratulations.
