489 Yards: Dustin's Drive Won't Count As Tour's Longest Drive Ever

Dustin Johnson hit a 489-yard driving during his round 3, 2018 WGC Dell Match Play face-off with Kevin Kisner (eventually losing the match 4&3). 

As Rex Hoggard explains for GolfChannel.com, the drive does not count as the longest in PGA Tour history because the Match Play records are not included. But remember, the numbers at non-major venues, and non-match play venues are flat so these more athletic players today are not hitting it longer except when they are.
