Spieth's incredible closing stretch clinches 2017 Open Championship

In the end, it was nice of Jordan Spieth to make things interesting before putting the hammer down in the most impressive finish in the history of major championship golf.

The 23-year-old overcame a disastrous start to his day by going absolutely bonkers on the final five holes, making three birdies and an eagle to run away from Matt Kuchar.

The final number was a 1-under 69 to finish at 12-under for the championship, but the closing 18 was anything but routine.

Spieth entered play Sunday with a 3-stroke lead over Kuchar but lost that advantage right away with three bogeys in his first four holes. He would settle down slightly, holding a 1-shot lead standing on the 13th tee.

It was then that the fun really began, as Spieth drove his ball more than 100 yards offline to the right, prompting an absolutely incredible scene as he decided what to do. After stalking around for over 20 minutes, he eventually took an unplayable lie and walked over 100 yards back to the practice range to hit his third shot. He somehow launched one beside the green and was able to get up-and-down for a bogey.

Kuchar's par on the hole would tie the score, but Spieth wasted no time in pulling away. After nearly acing the par-3 14th, Spieth drilled a 50-foot eagle putt on 15 before pouring in birdies on 16 and 17 as well to send the patrons at Royal Birkdale into hysterics.

A closing par would see Spieth become the only player in history to win 10 PGA Tour events and three majors before his 24th birthday, and he matches Jack Nicklaus as the only players with three major wins prior to that date.
