Players 30 and older make big splash at Sony Open, and tennis trend might continue

As the highest-ranked American in men's tennis, Sam Querrey watches all of the recent success by players in their 30s and likes what he sees.

Men 30 and older made a big splash at the Sony Open last week, including semifinalist Tommy Haas, at 34 the oldest player in the ATP World Tour's top 50, and runner-up David Ferrer, who lost a thrilling final to Andy Murray. Serena Williams, 31, became the oldest women's champion.

It's a trend that might continue into the clay-court season that began Monday, and beyond. The 25-year-old Querrey says the success of older players gives him more motivation to have a long career.

The Sony Open had 22 thirtysomething men in the draw, compared with four 20 years ago.
