(CNN) -- Henrik Stenson kept his cool to collect the biggest paycheck of his career Sunday, landing a $10 million FedEx Cup jackpot along with the $1.44 million prize for winning the Tour Championship in Atlanta. The Swede, who also collected $1.44 million for winning the Deutsche Bank Championship earlier this month, finished three shots clear of young American hope Jordan Spieth and veteran Steve Stricker. The 37-year-old went into the final day at East Lake with a four-stroke advantage, having been nine ahead halfway through Saturday's round, but Spieth ate into that as he fired a superb six-under-par 64.
