Henri Laaksonen replaces Roger Federer at top of Independent Swiss rankings, 1st time since April 2001 that Federer is not Swiss No. 1

The new Rado Swiss Tennis rankings were published recently and for the first time since April 2001, Roger Federer is not heading the list.

The list is published biannually by Swiss Tennis, the governing body of tennis in Switzerland. As per the new list, Henri Laaksonen leads the rankings in the men's section while Belinda Bencic heads the women's section.

However, it is important to note that the Swiss rankings are separate from the ATP rankings. Roger Federer is still the top-ranked Swiss player in the ATP rankings, with Federer ranked 43 in the world while Laaksonen is ranked 91st.

The rankings, published twice a year, are valid for official tournaments and interclub and junior interclub championships.

The classification process is as explained below.

"All victories or defeats within 12 months are taken into account for the classification. It doesn't matter how close a win or loss was or how many sets/points were won. The classification is calculated twice a year - in autumn and spring."

"For the spring classification, all results from April 1st to March 31st are taken into account, for the autumn classification those from October 1st to September 30th count. The period between the two classification calculations (autumn/spring) is called the classification period. Accordingly, the results from 12 months or, in other words, the last two classification periods count for the classification."

Roger Federer was last seen in action at Wimbledon last year, where he lost to Hubert Hurkacz in straight sets. He has since been recovering from knee surgery.

No place for Roger Federer, Stan Wawrinka in new rankings list

The two biggest names in Swiss tennis history -- Roger Federer and Stan Wawrinka -- do not feature at all on the latest rankings list.

According to Swiss Tennis' official website, the national rankings of Roger Federer and Wawrinka were frozen at the end of March on account of the injury breaks that the two players were on.

With Roger Federer's ranking being frozen, Henri Laaksonen, who achieved a career-high ranking of World No. 84 in February this year, is the new top-ranked player in Switzerland.

Laaksonen, who was born in Finland, has previously made it to the third round of the US Open and the French Open, his best finish in Grand Slams thus far.

Stan Wawrinka, meanwhile, will return to tour action at the Monte-Carlo Masters after a prolonged injury break. He will take on Alexander Bublik in his opener.
