Xander Schauffele turned pro in 2015 and quickly gained his PGA Tour card during the 2017 season. Throughout his entire career as a pro, Schauffele has only ever had one man on his bag - Austin Kaiser.
The pair have known each other since their college days at San Diego State between 2011-2015 when they were both a part of the Aztecs' golf line-up. After graduating, Kaiser had ideas of becoming a police officer but was persuaded to join his friend on tour as a caddie.
