Americans have claimed 11 of the last 15 British Opens, but they are fleeing the leaderboard in the third round at the Old Course at St. Andrews.

With the final groups making the turn, there are more players in the top-10 from Sweden (three) – a country that has never produced a major champion -- than the U.S. (two).

So what are the differences between tall, interchangeable Swedes Henrik Stenson (7-under through 18), Robert Karlsson (5-under through 13), and Peter Hanson (5-under through 10), who always seem to clutter the leaderboard in majors?

Stenson, 34, is the best known as the guy who stripped to his skivvies to hit a shot from a muddy lie during the CA Championship at Doral. His caddie is Fanny Sunesson. He has finished in the top 10 in four of the last eight majors and has six wins on the European Tour and two on the PGA (2009 Players, 2008 Accenture Match-Play).

Robert Karllson, 40, is best known for his fantastic nickname, Ivan Drago. The tallest of the trio at 6-foot-5, Karllson has 10 European Tour wins and has been in the top-10 in three of the last seven majors in which he has played. Karllson won 2008 World Cup with Stenson.

Peter Hanson, 32, is 6-foot-3, has three European Tour wins, and has been in the top 20 in the last two U.S. Opens.

And if you think Thomas Bjorn belongs on this list. You’re wrong. He’s actually from Denmark and missed the cut by a stroke.
