Ivanovic, the 2008 French Open champion, tweeted Tuesday about the decision to step away from the tour until 2017 – making the announcement one week after losing in the first round of the U.S. Open.
She said she has a recurring wrist injury and was advised by her doctor to take time off. In addition, she will have surgery on a toe she broke at the Australian Open in January 2015.
Novak Djokovic, Caroline Wozniacki and Roberta Vinci will seek to return to the U.S. Open semifinals Tuesday, part of a lineup that also features two Frenchmen battling for a spot in the final four.
The No. 1-seeded defending champ Djokovic takes on ninth-seeded Jo-Wilfried Tsonga, one of three French players in the quarterfinals. The other two, 24th-seeded Lucas Pouille and 10th-seeded Gael Monfils, face off for only the second time. Monfils won the previous meeting in five sets at last year's Australian Open.
On the women's side, in a contest of unseeded players, the two-time U.S. Open runner-up Wozniacki plays Anastasija Sevastova, who had never won four straight matches at any major until now.
The other women's quarterfinal features two top-10 players: second-seeded Angelique Kerber, this year's Australian Open champ, and No. 7 Roberta Vinci, last year's U.S. Open runner-up.
The roof on Ashe may be a factor. Forecasts call for partly cloudy skies, blustery winds and a chance of afternoon showers.
