Former world number one Simona Halep appeared before the Court of Arbitration for Sport on Wednesday to appeal her four-year doping ban in what is expected to be a three-day hearing.

The 32-year-old Romanian was suspended last September by the International Tennis Integrity Agency (ITIA) after two separate doping infractions.

The two-time Grand Slam singles champion tested positive for roxadustat after the US Open in 2022 and was charged with a separate second anti-doping breach last year relating to irregularities in her athlete biological passport.

Halep, smiling and surrounded by her legal team, was seen entering CAS headquarters at the Palais Beaulieu in Lausanne, Switzerland but made no statement.

The CAS ruling will be delivered at a date yet to be announced.

Halep has protested her innocence and refused to accept the ITIA decision which will keep her from playing professional tennis again until October 6, 2026.

The winner of the 2018 French Open and 2019 Wimbledon singles titles says she wants to "clear her name" and has claimed experts found she had accidentally taken a contaminated supplement.

But the ITIA said while the tribunal accepted Halep had taken a contaminated supplement, they also "determined the volume the player ingested could not have resulted in the concentration of roxadustat found in the positive sample".

Roxadustat is a substance that can be used legitimately to treat anaemia.

But it is also on the World Anti-Doping Agency banned list as it is considered a blood-doping agent, which increases haemoglobin and the production of red blood cells.&nbsp;

The biological passport system is designed for the long-term monitoring of an athlete's blood indicators with the aim of identifying irregularities that could indicate doping.

Tennis: Simona Halep appears before CAS to appeal four-year doping ban

The World Anti-Doping Agency (WADA) has begun to build cases against drug cheats with the help of raw data retrieved from a Moscow laboratory as the Russia doping investigation enters a new and perhaps final phase, WADA said on Thursday.

Gunter Younger, WADA's director of intelligence, told the Foundation board that the <a href="https://www.wionews.com/sports/wada-retrieves-more-than-2000-samples-from-tainted-moscow-lab-214962">first cases built on data mined from the infamous lab</a> had been turned over to international federations and he expected that work to be completed by the end of the fourth quarter this year.

After forcing Russian authorities in January to surrender raw data stored in the Moscow lab and later securing thousands of urine and blood samples, WADA is in the process of analysing that material and connecting the dots that could lead to hundreds more sanctions.

Younger reported that 24 million documents of data have been analysed and are being compared with multiple other sources, including Laboratory Information Management System (LIMS) data obtained through a confidential source in 2015.

"We have already started, one federation has already received a package," Younger told Reuters. "There was a very high degree of matching between the data collected in January and the LIMS data.

"The strongest cases we have now identified.

"We will now start with case one we consider strongest, get into the data base get the raw data and with our raw data we go to our lab experts.

"The lab experts look at raw data and say yes this is a really strong case go ahead. Then we prepare all the evidence and approach the federation."

WADA has been under immense pressure to deal with Russia since a 2015 report outlined evidence of state-backed, systematic doping in Russian athletics which was amplified a year later when a report by Canadian lawyer Richard McLaren revealed doping and testing manipulation across many sports.

The heat was turned up last September when the WADA executive committee, ignoring the outrage of numerous athletes groups, voted to reinstate the Russian Anti-Doping Agency (RUSADA) before it had fulfilled the requirements laid out in a Roadmap to Compliance, including access to data in the Moscow lab.

After being bombarded by criticism and with an end to the long-running doping saga now in sight, a vindicated WADA president Craig Reedie is confident that history will show they made the right decision by provisionally reinstating RUSADA.

"Successfully getting the data and then the samples was the real game changer," Reedie told Reuters. "The accusation is that we were weak on Russia but if you look at it, it was our Compliance Review Committee who decided to try to break the logjam on the compliance of RUSADA.

"Instead of waiting for Russia to come to us we actually went to them saying we will make you compliant if you deal with these conditions and they did," Reedie added.

"Was it the right decision, yes it was, loud and clear and we have delivered. I would be happy if the rest of the world now understood WADA did the correct thing."

WADA's Russian investigation enters new phase

Providing a major relief to Narsingh Yadav, the Court of Arbitration for Sports (CAS) on Thursday gave a clean chit to the grappler to participate in the 74kg men&#39;s freestyle category at the ongoing Rio Olympics. 
 
On Tuesday, Narsingh&#39;s Rio campaign hit another roadblock when the World Anti-Doping Agency (WADA) decided to appeal the CAS against the clean chit given to him by the National Anti-doping Agency (NADA) in New Delhi connection with doping charge.&quot;Narsingh Yadav has been cleared by the CAS,&quot; confirmed lawyer Vidushpat Singhania. 
 
The decision means Narsingh will now kick start his Rio campaign on Friday when he takes on France&#39;s Zelimkhan Khadjiev in the qualification round. Earlier, NADA had paved the way for Narsingh to compete in the prestigious quadrennial event after its disciplinary panel exonerated the 26-year-old grappler from the charges of violating anti-doping rules saying he was a victim of sabotage perpetrated by a competitor. 
 
Narsingh, who bagged the quota with a bronze medal finish in last year&#39;s World Championships, tested positive for a banned anabolic steroid on both his A and B samples. He was kept under provisionally suspension until the NADA&#39;s verdict.Wrestling Federation of India (WFI) president Brij Bhushan Sharan Singh had earlier expressed his confidence that the embattled wrestler would be cleared by the CAS in his doping case. 
 
&quot;WADA has appealed in the CAS. We have presented our case to WADA. They have set a hearing for August 18. Our lawyer will not be able to reach here by that time and, therefore, he will mark his presence either through telephone or video conference. I am totally confident that Narsingh will clear this hurdle as well. Our case is not at all weak,&quot; Brij Bhushan had then said. 
 
Interestingly, Narsingh was also selected for the Rio Olympics in controversial circumstances as two-time Olympic medallist Sushil Kumar had demanded for trials to determine who should go to the games. In the end, Narsingh was favoured for the same after fighting a lengthy legal battle with Sushil.
