Day nails monster putt, doesn't even retrieve ball

Jason Day didn't win the Tournament of Champions in Hawaii, but he can lay claim to this incredible effort.

The Australian world No.2 made eagle to kickstart his final round, draining a mammoth 75-foot putt.

But the best part was Day's reaction.

The putt was so long he simply walked away with a cheeky grin, leaving his caddie to pick the ball out of the hole.

World No.1 Jordan Spieth ran away with the season-opening event, ruining Day's hopes of regaining golf's top spot.
