"I apologize to Richard McEvoy and the fans for my brevity on 18", world number 23 wrote on Instagram.
This year's Memorial Tournament victor could do with a big performance as he bids to make an American Ryder Cup team that will have a few players who show their emotions on the course, with Patrick Reed and Bubba Watson sure to rile the European crowds in Paris from 28-30 September! "You get a lot of self confidence with handling a situation like that".
"I've tried to enjoy my golf as much as possible".
The man who eventually scuppered John's dream of victory on home soil was 39-year-old journeyman McEvoy.
Since turning pro 17 years ago, McEvoy has plied his trade between the Challenge Tour and European Tour. What a massive step forwards for him, as he won €333,334, whilst the total prize fund for the Challenge Tour event was just '€210,000.

The Englishman, who is yet to win on the European Tour, took the outright lead with birdies at No. 9 and No. 11 before play at the Green Eagle Golf Course was suspended for nearly three hours due to lightning storms.
"It's incredible", McEvoy told reporters. 'I've waited a long time for this.
McEvoy secured his first European title on his 285th attempt following a victory on the Challenger Tour in France the previous week.
McEvoy has had the month of his life, one that started with a victory in a pro-am at Queenwood in Surrey, where he came out on top against the likes of Rory McIlroy and Justin Rose with a course-record 64.
"I fought hard, I believed, and even at the last I overpowered my caddie to lay it up to give myself the best opportunity to make birdie and I managed to do it", McEvoy said of his approach to the last. A lot of bad years, a lot of good years but it had never quite happened.
