ZACH JOHNSON has revealed how the Meltdown at Medinah will continue to haunt him - until the United States win back the Ryder Cup from Europe.

Johnson and his countrymen had looked certainties to triumph in the biennial competition back in 2012 after romping into a commanding 10-6 lead.

But Davis Love III's star-studded side suffered an astonishing collapse on the final day and Jose Maria Olazabal's team was victorious against all the odds.

Europe won eight and halved one of the 12 singles matches to record a 14.5-13.5 victory that has since been dubbed the Miracle at Medinah.

But for 2007 US Masters champion Johnson there was nothing miraculous about one of the worst capitulations in the history of sport never mind golf.

He revealed that events in Illinois two years ago still prey on his mind - and will continue to do so until the Samuel Ryder Trophy is back on the other side of the Atlantic.

"I am probably not completely 100% over it," the 11-time PA Tour winner admitted. "It was very frustrating for all of us involved in the United States team.

"It is not that I am losing sleep over it or anything. What it boils down to is that I felt bad for Davis (US captain Davis Love III). I felt we let him down."

Johnson added: "The United States guys who are hungry for the Ryder Cup, the regular team members and the guys who haven't played yet, know what matters now.

"We are all determined to put what happened at Medinah two years ago behind us and win back the Ryder Cup at Gleneagles."

Johnson and compatriot Jason Dufner had the misfortune to find themselves up against Rory McIlroy and one Ian Poulter in the fourball matches on the second day at Medinah.

The Americans appeared to be heading for a comfortable win that would have given the home team what would surely have been an unassailable 11-5 lead. But English star Poulter then produced one of the greatest performances in the 85 year history of the event - by birdieing the final FIVE HOLES to secure an amazing one hole win.

Johnson recalled: "If it hadn't been for the putts that Ian holed in that match on the Saturday afternoon then Europe probably wouldn't have won.

"The Ryder Cup brings out the best and worst in every player. And for some reason it brings out the best in Ian every two years. But the bottom line is he played phenomenal golf."

The 38-year-old is one of many players who have been less than complimentary about the PGA Centenary course the Ryder Cup will be played on in September.

But he was pleased to hear United States captain Tom Watson speak positively about the remodelled Jack Nicklaus course after making a reconnaissance visit there last week.

And Johnson reckons the course for the eagerly-anticipated contest with Paul McGinley is not as important as hitting top form during the week of the competition.

He said: "It isn't a bad golf course, but it isn't the best I have played over here.

"The best I have played at are Turnberry, Royal Lytham, Muirfield, and Wentworth is pretty good too.

"Gleneagles is going to be absolutely fine. I have played in three Ryder Cups now and I haven't played a phenomenal golf course yet.

"But you don't have to. If you have a good golf course with great infrastructure you will be fine."
