Rypien finished with 27 points at Edgewood Tahoe Golf Course under the modified Stableford scoring system that awards graduated points for pars or better.
"I got it going on my first nine holes and scored 19 points on that side. By far my best in all the years I have played here," said Rypien, who started play on No. 10. "The fountain of youth is not in my favor, but I think I am playing better golf now than when I first came out here."
He eagled the par-5 16th, hitting a hybrid club to 8 feet.
Actor Lucas Black was second with 25 points, followed by former NFL quarterback Chris Chandler with 24. Former Denver quarterback John Elway, Golden State guard Steph Curry and former NHL player Jeremy Roenick were tied for fourth place with 22 points.
Defending champion Dan Quinn, a five-time winner and former NHL player, struggled with only 13 points.
