So many great matches. What to watch? You cannot go wrong with any, but here are a few suggestions.
On Center Court, this will be a contrast in styles between ninth seed Daria Kasatkina and Amanda Anisimova. Kasatkina has just re-entered the world's top 10 after a resurgent year, just winning a tournament a few weeks ago in San Jose. Her game of variety and running down every ball goes up against the big hitting Anisimova who has one of the sweetest backhands you will ever see that has helped her rise more than 60 spots in the rankings this year.
Following that match is a blockbuster of Grand Slam major winners Andy Murray against Stan Wawrinka. Each has three major titles, but Murray also has two Western & Southern Open titles, so he has proved he is comfortable on the Cincinnati courts.
Fans from Cincinnati will want to cheer on two local players, J.J. Wolf and Caty McNally. Wolf is having the best summer of his career, rising to a career-high ranking of No. 84 with lots of wins over top players. McNally is known as one of the best doubles players in the world, but she is a singles force, as well. The hometown crowds can make a difference!
Australian Nick Kyrgios and his mate Thanasi Kokkinakis have proved to be not just an entertaining doubles team, but a winning one. They won the Australian Open title in January. They take on the Italian pair Fabio Fognini and Simone Bolelli.
