The USTA has announced that defending champion Jack Sock of Lincoln, Neb., and reigning Orange Bowl champion Lauren Davis of Gates Mills, Ohio, will be the top seeds at the 2011 USTA Boys’ and Girls’ 18s National Championships. The USTA Boys 18s National Championships will take place Aug.5-14 at Kalamazoo College in Kalamazoo, Mich., while the USTA Girls 18s National Championships will take place Aug. 6-14 at the Barnes Tennis Center in San Diego. The winners of the USTA Boys’ and Girls’ 18s National Championships are awarded wild cards into the U.S. Open men’s and women’s singles main draws.

Sock, who turned professional last month, is looking to become the first player to win consecutive USTA boys 18s titles since Donald Young in 2006-2007. Last year, Sock became the first American to win the US Open boys singles title since Andy Roddick in 2000, and the first USTA 18s champion to accomplish that feat since Brian Dunn in 1992. Davis ended 2010 on a 32-match winning streak that encompassed two USTA Pro Circuit titles, three ITF World Junior titles including the US Open, and a victory at the USTA Australian Open Wild Card Playoff to earn a main draw wild card into the 2011 Australian Open.

Other top seeds in the boys’ 18s field include: Number two seeded Mitchell Frank of Annandale, Va., who has the second-highest ATP World Tour ranking of any player in the field behind Sock; number three seed Bjorn Fratangelo of Pittsburgh, who became the first American to win the boys’ singles title at Roland Garros since John McEnroe in 1977; and number four seed Marcos Giron of Thousand Oaks, Calif., who earlier this year became the first boy to win the USTA International Spring Championships and the Easter Bowl in back-to-back weeks since Sam Querrey in 2005.

Other top seeds in the girls’ 18s field include: Number two seed Krista Hardebeck of Santa Ana, Calif., who won both the USTA International Spring Championships and the Easter Bowl in 2010; number three seed Madison Keys of Boca Raton, Fla., a finalist at the 2011 USTA International Spring Championships; and number four seed Nicole Gibbs of Santa Monica, Calif., who reached the final at the USTA Girls’ 18s National Championships in 2010, and as a freshman helped the Stanford Cardinal reach the 2011 NCAA women’s team final.
