Golf's top 25 was once dominated by US players but in recent times non-US payers, from Europe and the rest of the world, have been filling the top spots.
The weekend's events saw three Europeans vying for world number one with Lee Westwood finally coming out on top ahead of Luke Donald and Martin Kaymer.
US golfers have been struggling to match their European counterparts in major events during 2010 and in the first few months of 2011.
Tiger Woods used to be the player US golf could count on but even he has struggled to keep up with the plethora of non-US players.
He hasn't won a PGA Tour event since September 2009, hasn't won a major since June 2008 and his five-year reign at the top of the world rankings ended in October.
It was only in the final round of the Masters, where he pulled on his famous red golf shirt and began a charge for the lead, that he looked like the Tiger of old.
He failed to complete the task and was beaten to the Green Jacket by non-US player Charl Schwartzel.
All of the majors are currently possessed by non-US players and the Ryder Cup is in Europe's trophy cabinet so is this a lasting changing of the old guard?
