With his fifth win of the season Sunday at the Tour Championship, Jordan Spieth earned a record haul on the PGA Tour in offical earnings—$12,030,465 (he earned another $1 million in unofficial money, although no doubt his financial advisor counts it as official). With the $10 million annuity for winning the FedExCup, the total amount surpasses Tiger Woods's 2007 record of $22,090,707. Add in his endorsement income with Under Armour, AT&T, Titleist, NetJets, Perfect Sense, Super Stroke, and Rolex, and he earned more than $50 million this year. But what really puts his year in perspective is that he paid his caddie, Michael Greller, more than $2.2 million if Spieth gave him the going rate: five percent of his earnings outside the top 10, seven percent inside the top 10, and 10 percent of the winner's purse, including the FedExCup bonus. Greller's earnings would have put him 38th on the 2015 PGA Tour money list this year just ahead of Phil Mickelson. Not bad for a former sixth-grade teacher who was earning $77,000 a year before taking a leave of absence to caddie for Spieth two years ago.
