(CNN) -- Jim Furyk is golf's latest $10 million man as he claimed the Tour Championship and the jackpot bonus for winning the FedEx Cup playoff series.
The American kept his nerve on the final hole to hold off England's Luke Donald by one shot on eight-under 272 at East Lake.
Retief Goosen of South African finished third at six under with England's Paul Casey and Nick Watney tied for fourth a further shot back.
All five were eyeing victory and the massive bonus prize, with American Charley Hoffman, who claimed sixth spot, also in the hunt on the final day.
But in the end, it boiled down to a battle between Donald and Furyk, who will be on opposing sides in the Ryder Cup between Europe and the United States at Celtic Manor later this week.
Donald resurrected his hopes on the back nine with three birdies, chipping in at the 17th to set the clubhouse pace on seven-under 273.
Fuyrk had scrambled brilliantly all day in wet conditions made worse by a storm which halted play for nearly two hours.
Leading by three with three to play, he bogeyed the 16th and 17th and came to the tough 235-yard par-three 18th needing a par to win the tournament, itself worth $1.35 million, and to clinch the FedEx series prize.
The 40-year-old pushed his tee shot wide into a greenside bunker but he splashed out to just over two feet and holed the putt before pumping the air in celebration and relief.
Donald, who like Furyk carded a final round 70, was watching in the scoring trailer and waiting for a possible playoff.
"It's a special moment," Furyk said after holing the winning putt. "What a special year."
Earlier, Watney, who carded a third round 63, had rattled through the front nine in just 30 shots and looked set to secure a remarkable victory, but after the storm delay his challenge fizzled out.
Matt Kuchar, who came into the event as the series leader, finished tied for 25th with Steve Stricker while Phil Mickelson closed with a disappointing 74 to leave the absent Tiger Woods still world number one.
