Jon Super/APJordan Spieth, right, speaks to his caddie, Michael Greller. Jordan Spieth is having one of the best seasons in PGA Tour history, and, as a direct result, so is his caddie, Michael Greller. In 19 events so far this season, Spieth has 12 top-10 finishes and five wins, including the Masters and US Open. That has added up to $9.7 million in winnings and $8.7 million on the official Tour money list*. The latter is more than twice as much as anybody else on the Tour this season.
