There was a Sky Cart first at the WGC-Cadillac Championship, as Butch Harmon joined his son Claude Harmon III to take a closer look at The Blue Monster at Doral.
The father-son combination discussed how the Trump National course has changed over the years, plus looked at the best ways to tackle the venue's daunting closing stretch.
Butch reflected on his own memories of playing the course, with the pair also looking back at some of the memorable winners at the venue.
