Wozniacki, Nadal and more enjoy the sights of Rome

The stars of the ATP and WTA are soaking up their time in one of the most historic cities in the world, Rome. Rafael Nadal certainly knows his way around the Italian Open.

Four-time champion Novak Djokovic got off to a winning start with a straight-sets win over Alexandr Dolgopolov.

Venus Williams will try to get her first win on red clay this season after an early loss in Madrid. She's even in the doubles draw, with Madison Keys.

The action isn’t all just on the courts as the players made an effort to see the Eternal City. Garbine Muguruza visited the center of the Catholic faith, Vatican City.

Stan Wawrinka's comeback struggles continued with a first-round loss, but not before he got in some of the best local cuisine, fresh pasta.

Caroline Wozniacki toured the sights with her fiancé David Lee.

Maria Sharapova, who's hoping her quarterfinal run in Madrid is a sign of good things to come, savored some pizza.

Though Madrid champion Petra Kvitova pulled out of Rome, she still spent a day in the incredible city.

Last but not least, Karolina Pliskova may have found the best views of the sprawling metropolis.

Main draw action in Rome began on Monday.
