Former world number one Caroline Wozniacki has withdrawn from the Mutua Madrid Open and the Internazionali BNL D'Italia in Rome due to a right ankle injury. Wozniacki sustained the injury during training in Monte Carlo two weeks ago. The injury puts the Dane's appearance at Roland Garros in doubt, with Wozniacki only scheduled to play Strasbourg the week before the French Open, followed by the second major of the year. Wozniacki, who has already withdrawn from Fed Cup and Istanbul, took to Twitter to announce her withdrawal. 

Wozniacki's injury-plagued 2015

After enjoying a resurgent 2014, the Dane came into 2015 with high expectations. After having a solid first half of the year, the tennis gods went after Wozniacki week-by-week. In Eastbourne, the former world number one suffered a lower back injury only three days before Wimbledon, causing her to retire from her semifinal match against eventual champion Belinda Bencic. Still feeling the effects of the back injury, Wozniacki struggled at Wimbledon, falling in the fourth round to eventual finalist Garbiñe Muguruza.

Wozniacki's bad luck continued when the Dane injured her calf less than a week before the Bank of the West Classic in Stanford, where the former US Open finalist crashed out in her opening match. The calf injury kept plaguing the world number 24, causing two more opening match exits in Toronto and Cincinnati. With no match wins to her name so far in the Emirates Airline US Open Series, the four time New Haven winner made the semis, before another disappointing second round loss in New York. The Dane ended her season with a round robin loss in Zhuhai to Svetlana Kuznetsova before having to withdraw due to a sliced finger, a freak accident from slicing bread, an incident that told the story of much of Wozniacki's 2015 season.

Wozniacki's previous Madrid and Rome results

With clay being Wozniacki's worst surface, her results in Madrid and Rome have been fairly average to the Dane's standards. The former world number one's best result in Madrid came in her debut performance in 2009, where she fell in the final to Dinara Safina. The world number 24's best Rome result came in 2011, where she lost to eventual champion Maria Sharapova in the last four. Last year, Wozniacki made the quarterfinals in the Spanish capital, before falling in her opening match in Rome. The Dane is next scheduled to play at the Internationaux de Strasbourg.
