Italy's Sara Errani banned for doping violation
Italian player Sara Errani has been suspended for two months for an anti-doping violation, the International Tennis Federation (ITF) confirmed on Monday.
The 29-year-old former French Open finalist failed the out-of-competition test in February after a urine sample was found to contain letrozole - a substance used in the treatment of breast cancer which is also on the banned drug list of the World Anti-Doping Agency (WADA).
It is described as an aromatase inhibitor that can act as a hormonal and metabolic stimulant.
An ITF statement said Errani was charged with an Anti-Doping violation on April 18 and had promptly asked for a hearing before an Independent Tribunal.
Nadal has eyes on world number one ranking in Montreal
Rafael Nadal will return to the top of the ATP world rankings for the first time in three years if he reaches the semi-finals at this week's Rogers Cup in Montreal.
The 31-year-old Spaniard, top seed in Canada in the absence of current world number one Andy Murray, ended last year ranked nine after taking time off to recover from a wrist injury.
While the return of the Mallorcan to the summit would be an incredible turnaround, the French Open champion is refusing to get carried away as he seeks a fourth Rogers Cup title.
"I don't even think about that now. I'm trying to have the right preparation now and that's it," Nadal told the ATP's website.
"I'm going to keep trying to play the way I did in the first part of the season, so if I'm able to make that happen, I hope to have a chance to do well," said Nadal, who is preparing for his first action since losing an epic contest to Gilles Muller in the fourth round of Wimbledon.
Fifteen-times grand slam champion Nadal has spent a career total of 141 weeks as world number one -- seventh on the list.
Murray, who is missing from Montreal as he treats a hip problem, has been ranked number one since last November having claimed five successive titles.
Nadal opens in Montreal against either Croatia's Borna Coric or Russian Mikhail Youzhny.
Second seed Roger Federer also returns to action in Montreal having won his eighth Wimbledon title last month.
The 35-year-old Swiss is also challenging to return to the world number one spot he has occupied for a record total of 302 weeks during his career.
