"This is such an amazing feeling. This never gets old," said Kuchar, who won for the sixth time in his career. "To have Jack Nicklaus congratulate me is a real treat. This is as special as it gets."
Woods made another triple bogey two shots from a bunker, three putts from 15 feet on the fringe at the par-3 12th and had to rally for an even-par 72. Woods came into the Memorial having won three times in his last four starts, and left with the second-highest score of his career at 8-over 296.
Russ Cochran won the Principal Charity Classic in Des Moines, Iowa, for his fourth career Champions Tour title, closing with a 5-under 67 for a one-stroke victory over St. George's Jay Don Blake.
Cochran finished at 11-under 205 at Wakonda Club. The left-hander, two strokes behind second-round leader Duffy Waldorf entering the day, broke a winless streak that stretched 35 tournaments.
Blake shot 69. He bogeyed the par-3 17th with his first three-putt of the tournament to fall a stroke behind. He had a chance to force a playoff, but his birdie try on the par-4 18th missed to the right.
Blake has finished second five times in Champions Tour events and has won three titles.

The Australian had a 4-under 209 total on The Bay Course at the Stockton Seaview Hotel and Golf Club.
