Jimin Kang, who saw plenty of time on the LPGA Tour last season, closed with a 3-under 69 to join Kathryn Cusick (72) one stroke further back at minus-8. Hong Mei Yang, from China, ended with an even-par 72 to finish at 6-under-par 210.
Wright, leading by one stroke heading to the final hole, was talked into laying up with her second shot by caddy and coach Leith Wastle. The move paid big dividends.
She knocked her third shot on the green some 30 feet from the cup. After Cusick was unable to convert her birdie attempt, Wright needed a par to secure the win.
Wright, who won the Isleta Futures Golf Classic earlier this year, two-putted from 30 feet out for par and the win.
'I'm an aggressive player,' said Wright, who earned $8,400 for the win. 'If I see a shot and feel it, I'm going to take it. If I had been a stroke behind, maybe I would have tried that big second shot (on No. 18). I knew I just had to sink my putt to win. I didn't get ahead of myself.'
Last year in her rookie season, Wright missed the cut and caddied for friend Kate Macintosh in the final round. The experience helped greatly.
'I learned a lot that day,' Wright said. 'I said, 'I'm not going to do that again. I'm not going to miss the cut.''
Last week's New Innsbrook Golf Classic winner, Naree Song, finished alone in fifth place at 5-under-par 211. Fellow Korean Sung Ah Yim, Australian Dana Lacey and Americans Lisa Fernandes and Marianne Morris shared sixth place at minus-5.
Young Jo of Korea and Columbian Cristina Baena finished at 2-under-par 214.
