We all know Dustin Johnson can hit the ball crazy distances, but the world's number-one golfer took things to extremes on Saturday as he boosted his chances of victory at the WGC-Mexico Championship.
Johnson began round three of the event at Club de Golf Chapultepec three behind leader Rory McIlroy and wasted little time in trimming that deficit to a single stroke - driving the green at the par-four first to set up an eagle.
Now we've seen plenty of par fours driven before, of course. However, Johnson got the job done - on a hole spanning 322 yards - with a two-iron.
The opening hole at Chapultepec is downhill and the entire course is at high altitude, enabling players to hit the ball further than usual.
Even so, this is just insane.
