COLLEGE STATION, Texas -- Defending champion Matais Boeker of Georgia and fourth-seeded Jesse Witten of Kentucky beat Stanford players Sunday to advance to the NCAA tennis final.

The top-seeded Boeker, a junior from Argentina, beat David Martin 6-4, 6-4, and Witten, a freshman from Naples, Fla., edged Ryan Haviland 6-4, 5-7, 6-1.

Boeker, who beat Witten in a third-set tiebreak in March in a dual match, said he doesn't feel any pressure as defending champion.

``I try not to think about it,'' Boeker said. ``If I do, it's pressure that I don't want. I'm just trying to have fun for my last college match of the year.''

Witten is taking the opposite approach.

``I had a tough match today and really had to mentally stay in it,'' he said. ``I look for nothing but the same kind of intensity tomorrow. I guess you're not really the best until you win it all, and that's my goal.''

Martin and Stanford teammate Scott Lipsky advanced to the doubles final, beating Duke's Phillip King and Michael Yani 7-6 (6), 6-3.

The second-seeded Cardinal duo will face Auburn's Andrew Colombo and Mark Kovacs, 6-4, 6-4 winners over Illinois' fourth-seeded Michael Calkins and Amer Delic.
