Nadal, Serena will play at MSG in March

Former world No. 1 stars Rafael Nadal and Serena Williams will be among those playing some exhibition tennis at New York's Madison Square Garden in March.

The 11-time Grand Slam champion Nadal, who will miss the upcoming U.S. Open due to knee problems, will face fellow former U.S. Open champ Juan Martin del Potro at the BNP Paribas Showdown.

The 14-time major titlist Williams, meanwhile, will take on currently top- ranked Belarusian star Victoria Azarenka at the Garden.

Williams beat her older sister Venus at MSG in 2009.

The French Open champion Nadal, del Potro and Australian Open titlist Azarenka will play at the Garden for the first time in their careers.
