Indian Wells, California:Stephen Ames started well and finished even better.
Ames, who won the first hole of the LG Skins Game a day earlier and hadn't won another since, sank a 7-foot birdie putt worth $650,000 (euro438,900) on Number 18 on Sunday.
Taking the title for the second year in a row, he finished with nine skins and $675,000 (euro455,800) of the $1 million (euro680,000) purse.
Five-time champion Fred Couples, playing in the 25-year-old tournament for the 14th time, also won nine skins, winning $325,000 (euro219,450) to push his career earnings in the made-for-TV event to more than $4.2 million (euro2.84 million).
Zach Johnson and Brett Wetterich, both playing in their first Skins Game, were shut out.
Ames, whose birdie on the opening hole of the tournament was worth $25,000 (euro16,880), didn't play particularly well again until the 18th.
He stuck his 9-iron from 142 yards out close enough to the pin for a good birdie chance, then watched the other three miss their considerably longer putts.
Johnson missed from 40 feet, Couples from 20, then Wetterich's 10-footer slid past the left edge of the hole to give Ames his chance.
He stroked the ball firmly into the center of the cup, and, beaming, accepted Couples' congratulations, then handshakes from the other two players.
Couples won the first hole of the second day of the two-day, 18-hole tournament with a 5-foot birdie putt for $250,000 (euro168,800) on Number 10.
From there, the holes were tied until Ames won eight skins on Number 18.
His winning total was $590,000 (euro398,400) in the tournament last year, when he clinched the title with a 3-footer for birdie worth $270,000 (euro182,320).
Couples finished second then, too, with $385,000 (euro259,980).
The first six holes were worth $25,000 (euro16,880) each, and Numbers 7-12 $50,000 (euro33,760).
The 13th through 17th carried a prize of $70,000 (euro47,270) and Number 18 was worth $200,000 (euro135,050).
In the Skins Game format, a player takes a skin by winning a hole. If the hole is tied by any of the players, the money carries over and all four remain in the hunt.
