LPGA Tour Veteran Ryann O'Toole Wins 2026 Aon Risk Reward Challenge and $1 Million Prize

After 15 years on the LPGA Tour, O'Toole earns a career-defining achievement through strategic decision-making, capping a standout season as she prepares to welcome her first child

NAPLES, Fla., Nov. 9, 2026 /PRNewswire/ -- Aon plc (NYSE: AON), a leading global professional services firm, and the LPGA Tour today announced Ryann O'Toole as the winner of the 2026 Aon Risk Reward Challenge, earning the Aon trophy and $1 million prize.

O'Toole's victory was built on a season of consistently making the right decisions when risk and opportunity were at its highest. Analysis of her performance on the Aon Risk Reward Challenge holes shows how she converted those moments into competitive advantage, finishing 22-under-par across her counting scores and delivering some of her best golf of the season when it mattered most.

Across 12 Challenge holes, with her two best scores counting on each, O'Toole finished 21-under-par on the par 5s, including four eagles. She hit 21 of 24 greens in regulation, or 87.5%, 22 percentage points higher than her overall season average and recorded 15 one-putts without a single three-putt.

Her performance on the Challenge holes reflected a broader transformation in her game. After ranking 125th on the LPGA Tour in par-5 scoring in 2025, O'Toole climbed to 11th in 2026, the best ranking of her 16-year career. At age 39, she also averaged a career-best 270.6 yards off the tee, combining improved distance with consistent execution to capitalize on opportunity throughout the season.

For O'Toole, those decisions extended beyond the golf course. Having built a commanding lead in the Challenge standings and secured the minimum number of rounds required to qualify, she made the decision to conclude her 2026 LPGA Tour season following the FM Championship as she prepared for the birth of her first child. It meant leaving the final outcome of the Challenge in the hands of the remaining field, confident in the position she had created through her performance across the season.

"Ryann is a veteran who knows exactly when to take a risk and how to deliver on it, and watching her win the 2026 Aon Risk Reward Challenge has been inspiring," said Craig Kessler, LPGA Commissioner. "A year after going back to Q-Series to earn her card, Ryann finished on top while playing a limited schedule, all while navigating her pregnancy and supporting her brother in his recovery from a severe accident. That's really special golf."

"Aon's philosophy of making better decisions in the face of uncertainty resonates with me more than ever this year," said O'Toole. "Sometimes the greatest rewards come from continuing to trust yourself, staying committed to what matters most, and embracing the opportunities in front of you, even when the path doesn't look exactly how you imagined."

A 15-year veteran of the LPGA Tour, O'Toole has built a career defined by dedication, perseverance and longevity. Her 2026 Aon Risk Reward Challenge victory represents one of the most significant achievements of her professional career, with the $1 million prize nearly doubling her highest single-season on-course earnings.

"Ryann's performance shows what better decision making looks like: understanding the risk, recognizing the opportunity and having the confidence to act when it matters most," said Anne Corona, CEO of North America, Aon. "We are proud to celebrate her as the newest Aon Risk Reward Challenge champion, and we wish Ryann and her partner, Gina, all the best as they prepare to welcome their first child."

O'Toole adds the Aon Risk Reward Challenge title to her list of career accomplishments, joining past champions Carlota Ciganda, Hannah Green, Minjee Lee, Angel Yin and Jeeno Thitikul and Jennifer Kupcho.

"For Ryann and Gina, as they get ready to welcome their son, I know this $1 million prize means a lot," said Kessler. We're so grateful to Aon for rewarding smart, brave golf and helping shine a light on stories like Ryann's. Congratulations, Ryann - we can't wait to see you back out here with your newest fan cheering you on."
