After Phil Mickelson tied the best score in major history at The Open, we look back at the social media highlights of the opening day.
Phil Mickelson was the headline maker on day one of the 145th Open Championship as he came close to a piece of golfing history.
The 2013 winner had a 16-foot putt at the last to card the first 62 in major history, only to be denied as a well-judged effort somehow lipped out.
Despite missing out on the lowest major score of all time, Mickelson is three clear of the field, with Patrick Reed and Martin Kaymer his nearest challengers.
Here we look at the social media highlights from an engrossing opening day's play at Royal Troon.
Second in 2005, Colin Montgomerie is very much an outsider for the Claret Jug but did at least display some resiliency to recover from a poor start before eventually finishing level par.
And Monty's caddie drew praise from one of last season's Super Bowl teams for his choice in headwear.
It did not take Reed long to make an impression, doing so in spectacular fashion.
Louis Oosthuizen is eight shots off the pace in his bid to regain the title he won in 2010, but will at least have the memory of a hole-in-one to cherish whatever happens.
Reed built on his early promise to set a Royal Troon record, but he would soon be outdone by his compatriot.
Off the course, a two-time major winner was on hand as the Premier League's greatest goalscorer tested his finishing on the putting green.
It was a rough start for U.S. Open champion Dustin Johnson, who went on to finish level par.
Despite a bogey-bogey finish, the omens are good for defending champion Zach Johnson, who is out to replicate Tiger Woods' 2006 triumph.
But it was Mickelson who stole the show with his agonising near-miss.
It may take some time for Mickelson's caddie to recover.
Mickelson's rotten luck earned the sympathy of a former world number one.
But Shane Lowry, who finished seven over, was pleased to see his hopes of a monumental comeback boosted.
