Lexi Thompson, meanwhile, was at her poised best – not her worst – on a Sunday in Mobile.
Lewis outlasted the rising teenager to win the Mobile Bay LPGA Classic by one stroke for her second LPGA Tour title in a round that supplied a measure of vindication for both.
Lewis, five strokes ahead early in the day, reclaimed the edge with a birdie on No. 16, while the 17-year-old Thompson parred the final hole and had to wait.
Lewis parred out. Her week was so solid that her finishing 3-under-par 69 was her worst round en route to a 17-under 271 total on The Crossings Course at Magnolia Grove, part of the Robert Trent Jones Trail. The former Arkansas star also won the 2011 Kraft Nabisco Championship.
“I’m getting more comfortable in this situation,” said Lewis, who earned $187,500. “I think that’s a lot of it, and it’s definitely been coming. I lost in a playoff in Australia, so I knew I was due.”
She has five top 10s in eight events this year, including a tie for second in the Women’s Australian Open.
Thompson made her earn it, and found redemption from her final-round fall in Mobile a year ago. She didn’t flinch under the pressure given a second shot, closing with rounds of 66 and 65, tying her career low in a bogey-free round.
NATIONWIDE TOUR: In Valdosta, Ga., Luke List won the South Georgia Classic for his first Nationwide Tour title, closing with 4-under-par 68 for a two-stroke victory over Brian Stuard.
The former Vanderbilt player finished at 16-under 272 at Kinderlou Forest, and earned $112,500.
EUROPEAN TOUR: In Seoul, South Korea, Bernd Wiesberger shot 4-under-par 68 to earn his first European Tour victory with a five-stroke win at the Ballantine’s Championship.
Wiesberger made four birdies on his way to claiming the win to become only the third Austrian to win on the European Tour after Markus Brier and Martin Wiegele.
Wiesberger finished at 18- under, five strokes ahead of Richie Ramsay.
LEGENDS TOUR: In Sun City West, Ariz., Rosie Jones won the season-opening Walgreens Charity Classic, finishing with 4-under-par 68 for a two-stroke victory over Elaine Crosby.
Jones had a 5-under 139 total on the Grandview Golf Course.
Crosby also closed with a 68.
