It was announced today that 21-time Grand Slam event champion and one of the greatest female players of all-time, Serena Williams, will take on close friend and former No. 1, Caroline Wozniacki, while current No. 4 men’s player Stan Wawrinka will square off with French star Gael Monfils in the 9th annual BNP Paribas Showdown at Madison Square Garden.

The entertaining one-night tennis event, which is being held on World Tennis Day for the fourth straight year has become a staple on the tennis calendar and is set for Tuesday, March 8.

The BNP Paribas Showdown is produced by MSG Sports and StarGames. Tickets starting at $35.00 will go on sale November 1 at 9:00 a.m. and can be purchased at the Madison Square Garden box office, online at www.thegarden.com and at all Ticketmaster outlets.

As in years past, the BNP Paribas Showdown at Madison Square Garden will once again headline a full day of worldwide activities as part of World Tennis Day, a global tennis participation effort. All events promote tailoring the game to players 10-and-under with smaller racquets, lighter balls and modified scoring.

Wawrinka and Monfils will make their Madison Square Garden debuts when they step onto the Garden court on March 8.
