Andy Roddick

'One of the coolest things about working with Brad was he came in, and he's like, "Listen, we're going to simplify things." It wasn't all this technical mumbo-jumbo. He made it very simple.' Andy Roddick, on working with coach Brad Gilbert

NEW YORK -- Serena Williams, who said she got teary-eyed as she watched Andy Roddick finish his last-ever tennis match, composed herself quickly. Williams, seeded fourth, beat 12th-seeded Ana Ivanovic of Serbia, 6-1, 6-3, Wednesday night at Arthur Ashe Stadium. Williams will play 10th-seeded Sara Errani in Friday's semifinals. Third-seeded Maria Sharapova will face top-seeded Victoria Azarenka in the other women's semifinal. This was Williams' 64th career win at the U.S. Open.

Andy Roddick's mojo was a no-show at the U.S. Open this week, leaving corporate sponsor American Express and Roddick fans to ponder "Where's Andy?" Roddick's first-round loss to Gilles Muller of Luxembourg on Tuesday night sent American Express scrambling to revise a cheeky advertising campaign that was supposed to have tracked the 23-year-old American's anticipated advance through the tournament.

Andy Roddick is rather busy these days. There's the "Saturday Night Live" hosting gig. The "Got Milk?" ad. The upcoming reality television show. Oh, yes, and then there's the little matter of trying to finish 2003 at No. 1 in the ATP Tour rankings. To do that, Roddick must fare better than French Open champion Juan Carlos Ferrero and Wimbledon champion Roger Federer at the season-ending Tennis Masters Cup, which starts Monday. "Even though I've accomplished a lot of my goals this year, I'm still in the hunt for No. 1," Roddick says.

Andy Roddick, Andre Agassi, Jennifer Capriati and Lindsay Davenport have committed to the Pacific Life Open to be played March 8-21 at the Indian Wells Tennis Garden. Others men's top 10 players entered in the ATP Masters Series event include Roger Federer, Juan Carlos Ferrero and Carlos Moya. Joining Capriati and Davenport in the women's field will be Belgians Justine Henin-Hardenne and Kim Clijsters, the top two players in the world.

Andy Roddick is going to try working with Andre Agassi's former coach. Roddick will get ready for Wimbledon under the guidance of Brad Gilbert, the former tour pro Agassi left early last year. A spokeswoman for Roddick said it's not a permanent move yet. Roddick split with coach Tarik Benhabiles after a second straight opening-round loss at the French Open. They spent four years together, during which Roddick won six titles and reached a career-high ATP ranking of No. 5.
