Jordan Spieth's long-time caddie Michael Greller has left the Mexico Championship after the death of his father.
The former sixth-grade maths teacher from the Seattle area and only caddie Spieth has had as a pro, learned that his dad, John Greller, had died on Tuesday night.
Spieth's father, Shawn, caddied nine holes of practice on Wednesday and will be on the bag the rest of the week at Chapultepec Golf Club.
Shawn Spieth only goes to a handful of tournaments outside the majors.
He wasn't planning to be in Mexico City this week until he decided to fly down from Dallas on Tuesday before Greller learned his father had died.
