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.
