On 9 November, the LPGA Tour and Aon announced Ryann O'Toole as the Aon Risk Reward Challenge winner, with a $1 million prize. The joint announcement also awards her the Aon trophy.
O'Toole's scoring built the winning campaign
The LPGA Tour and Aon's 9 November announcement records O'Toole at 22 under par across her counting Challenge scores. It says she made four eagles on the designated par-five holes, where her counting scores totalled 21 under par. Those scores reflect the scoring opportunities that shaped her season-long Challenge lead.
The LPGA Tour and Aon's 9 November announcement also says O'Toole hit 21 of 24 greens in regulation on those holes. Her decision to attack those opportunities came alongside a broader improvement in par-five scoring across the LPGA season. The Challenge title therefore rests on a documented set of scoring outcomes, rather than an individual tournament result.
LPGA Tour golfer O'Toole said, “Sometimes the greatest rewards come from continuing to trust yourself,” in the joint announcement. She linked the award to decisions made amid changes away from the course.
A ranking rise before a break from competition
SportsRivo's calculation from Aon's figures: 125th in 2025 minus 11th in 2026 equals a 114-place rise in O'Toole's LPGA par-five scoring rank. The comparison puts the Challenge outcome alongside improvement in a related measure across her tour season; it does not treat the Challenge and the tour ranking as the same competition.
O'Toole ended her LPGA Tour season after the FM Championship while preparing for the birth of her first child, according to the joint release. Having already established her Challenge lead, she left the final result to the remaining field. The award was confirmed after her playing season had ended.
What the award changes
- O'Toole receives the Challenge trophy and prize after the LPGA Tour and Aon confirmed the final result.
- Her par-five ranking improvement gives context to the scoring record behind the award.
- Her season has concluded, so the announcement recognises a completed campaign rather than a new start on the course.
