Sets and the City

With the start of the season's final Grand Slam event just days away, New York is in full U.S. Open mode. Before stopping by "The Late Show With David Letterman," Andy Roddick joined Nicolas Kiefer, Fernando Gonzalez, David Ferrer and a strangely thin-looking Jo-Wilfried Tsonga -- plus the ever-ubiquitous Bethenny Frankel -- at the W Hotel for the 10th Annual BNP Paribas Taste of Tennis, a celebrity-player cooking lesson to benefit the Food Bank for New York City. I'm not sure what any of the players whipped up, but based on the name of the event I'm guessing they all now know what balls taste like.

Defending champions Roger Federer and Serena Williams were looking fit at the 2009 U.S. Open Draw Presentation at the New York Times Center in Midtown.

Meanwhile, after ringing the opening bell at the New York Stock Exchange and receiving an Anti-Defamation League Americanism award, Venus Williams was on hand for the maiden voyage of the Zero Ferry, a free water taxi service from Manhattan to Queens running all next week for visitors to the U.S. Open. The complimentary service is provided by her sponsor, POWERADE ZERO, who will also be handing out bottles of Powerade Zero to thirsty fans taking the ferry to the tournament.

Venus and Serena -- along with Bud Collins -- also made a promotional appearance in Bryant Park for DIRECTV.

John McEnroe unveiled his new prostate cancer awareness billboard outside Madison Square Garden.
