Jeeno Thitikul birdied the last hole at Mountain Ridge Country Club to win the 2026 Mizuho Americas Open by four strokes, closing out a week that pushed her into another record book entry and added $487,500 to her season haul. Ruoning Yin finished four shots behind as Thitikul captured the ninth LPGA title of her career.
The victory made Thitikul, 23, the fastest player to cross $18 million in career earnings and extended her record as the quickest to hit every milestone from $8 million through $18 million. She has now made nearly $1 million in 2026 after two victories, with her first coming at the Honda LPGA Thailand. After the win, Thitikul said it meant the world and that it meant a lot to her.
The result also matters because the Mizuho Americas Open carried a $3.25 million purse, with prize money payouts reflecting one of the stronger stops on the schedule. Michelle Wie West, who served as the tournament host, had stressed the player experience around the event, which included free rooms, free transportation and player gifts such as $250 Delta and Starbucks gift cards. LPGA moms also received $1,000 Starbucks gift cards.
That hospitality framed a tournament that still came down to the scorecard. Thitikul’s closing birdie sealed a win, but the wider story was the combination of performance and payoff: a season gathering speed, a historic earnings mark and a field that left with more than just results. For Thitikul, the chase now shifts from one milestone to the next, and the pace she has set makes each stop feel like a test of whether anyone can keep up.
