• A good read from Douglas Robson: As the 2014 season kicks off, the expectations for U.S. tennis, aside from Serena Williams of course, remain questionable.
The longest Grand Slam title dry spell — now-retired Andy Roddick was the last U.S. male major winner at the 2003 U.S. Open — drags on.
On the women’s side, Serena Williams, 32, and Venus Williams, 33, remain the only U.S.-born Grand Slam winners in more than a decade. The sisters were groomed outside the USTA system.
But there are signs of progress: There were 11 American women in the top 100 in 2013, the most of any country. Many of the rising talents, such as Sloane Stephens, Madison Keys and Jamie Hampton, and most of the other under-23 women such as Christina McHale and 2009 U.S. Open quarterfinalist Melanie Oudin, have received on-and-off coaching and assistance from the USTA.
