“She’s got those new irons in the bag, Jerry, and I talked to her caddie…earlier and he said the mis-hits are just a little bit better than the old irons she used to play,” said Golf Channel analyst Morgan Pressl. 

“[She] told me yesterday they’re just more consistent feeling,” said on-course commentator Jerry Foltz. 

“Proto Concept congratulates the winner of the Gainbridge Championship,” said Yasufumi Kawasaki, Brand Producer of Proto Concept. “We are proud that she has chosen Proto Concept irons in order to bring her game to the highest level and we look forward to doing all we can to help her maximize her game.”

The C-05 irons feature a tour pocket cavity engineered with a deep and low center of gravity along with a clubface that is slightly thicker than standard (2.7 millimeters) in the middle and lighter on the heel and toe (2.4 millimeters) to add ball speed on mishits. Designed to increase distance and to enhance maneuverability, straight line performance, forgiveness and feel.
