The former sixth-grade math teach is going back to school.
That would be Michael Greller, who left his old job to caddie for Jordan Spieth in 2013. At Spieth’s request, Greller has been studying up on AimPoint, the methodology of reading greens that starts with using feet to feel the slope of the green and then holding up fingers for each percent of slope.
Among those who use it are Dustin Johnson and his brother, Austin, whom other caddies say has mastered the technique.
Spieth said Greller met with John Graham, the putting coach for Justin Thomas, for a crash course.
