Li Na and Caroline Wozniacki will face off in Hong Kong on March 4 at the AsiaWorld-Arena, adding to the line-up for the newly christened “World Tennis Day,” which also includes matches held in New York City. On the same day at Madison Square Garden, Serena Williams will play Victoria Azarenka, and Rafael Nadal faces Juan Martin del Potro. Both exhibitions are being called the BNP Paribas Showdown.

Ivan Lendl and John McEnroe will also renew their rivalry in Hong Kong.  
World Tennis Day is a new co-initiative by the president of StarGames, Jerry Solomon, and the International Tennis Federation. The idea is to hold several pro events around the world while at the same time tying them to grassroots programs that promote 10-and-under tennis.
