Seven Stanford tennis players were chosen to represent the Cardinal in the singles and doubles brackets of the NCAA tournament on Wednesday, with juniors Bradley Klahn and Ryan Thacher on behalf of the men’s team and senior Hilary Barte, sophomores Mallory Burdette and Stacey Tan and freshmen Nicole Gibbs and Kristie Ahn representing the women’s team.

Klahn, last year’s men’s singles champion, begins his title defense as one of the nine-through-16 seeds after finishing as the runner up in the Pac-10 championships over the weekend. He is 9-1 in his last 10 matches.

Thacher, the No. 46 player in the nation, was given an at-large bid into the tournament, and he will pair up with Klahn in doubles as the two try and improve on last year’s semifinals finish at nationals.

The stacked women’s side is anchored by Barte, who was awarded the No. 3 seed, but she has struggled down the stretch, with a 6-4 record in her last 10 matches.

Barte is closely followed by Ahn, the No. 15 player in the country, who earned one of the number nine-through-16 seeds.

Gibbs, Burdette and Tan all received at-large bids into the tournament field. Barte and Burdette will team up on the doubles side as the No. 4 overall seed, and Ahn and Gibbs pair up as an at-large selection.

The individual portion of the NCAA Men’s and Women’s Tennis Championship is scheduled for May 25-30, with singles play starting on May 25 and the doubles competition getting underway on May 26. All matches will be held at Taube Tennis Center.
