The event will be the second ever mixed team format event on the Champions Series tennis circuit featuring men’s and women’s legends competing throughout the year for prize money and the season-long points championship.

Clijsters and Sock will play as a team against Fernandez and Baghdatis, each playing a set of singles and then pairing for a deciding mixed doubles match.

The event will feature $75,000 in prize money with $50,000 going to the winning team and $25,000 to the runner-up. The winning team members will each be awarded 200 ranking points while the runner-up team members will be awarded 100 ranking points towards the season-long championship. Each player will also be awarded 100 ranking points for every singles match they participate in and an additional 100 ranking points for each victory.
