The current ATP World No. 1 Andy Murray is set to lose his number 1 ranking following next week’s ATP Masters 1000 event at Cincinnati. Following his stellar run last season to clinch the No. 1 ranking for the first time in his career, he has failed to maintain his form and fitness this season. He has confirmed that he will not be able to defend his 600 points at Cincinnati, and will consequently lose the No. 1 spot to either Roger Federer or Rafael Nadal.

As world No. 1, he has only been able to accumulate 2290 points in 40 weeks (41 after next week). Here we take a look at the players who have accumulated the least ranking points as the ATP World No. 1.

Note – The new points system introduced in 2009 has roughly doubled the points per event. Thus, Murray’s 2290 points would be worth approximately 1145 points, when compared to the previous points system. As such, the method used to calculate ranking points has changed several times over the years, and any interpretations of the following should take that into account.

Sl Name Weeks at No. 1 Points obtained as No. 1 1 Patrick Rafter 1 0 2 Thomas Muster 6* 3 3 Marcelo Rios 6* 28 4 Carlos Moya 2 64 5 Yevgeny Kafelnikov 6 172 6 Marat Safin 9* 250 7 Mats Wilander 20 258 8 Andy Roddick 13 475 9 Boris Becker 12* 597 10 Juan Carlos Ferrero 8 695

Interesting Points

Thomas Muster played 3 matches as the world No. 1. He lost all 3. His opponents were ranked 161, 40 and 114.

Pat Rafter was world No. 1 for just 1 solitary week. He did not play any event that week.

Ivan Lendl and Marcelo Rios are the only players to reach No. 1 without previously winning a Grand Slam tournament. Marcelo Rios is the only player to be No. 1 and never win a Grand Slam.
