   Unseeded Kristie Ahn, a 26-year-old Stanford graduate, surprised fifth-seeded Marie Bouzkova, a 20-year-old Czech, 6-3, 6-2 on Thursday to reach the quarterfinals of the $100,000 Dow Tennis Classic in Midland, Mich.
   Ahn, an American ranked No. 220, is scheduled to play top-seeded Rebecca Peterson of Sweden today. Peterson, ranked No. 57, dismissed 14-year-old wild card Cori (Coco) Gauff of Delray Beach, Fla., 6-2, 6-1 in 56 minutes.
   Gauff, at 13, became the youngest player to reach the U.S. Open girls final and, at 14 last year, the youngest to capture the French Open girls title since Martina Hingis won her second crown there in 1994 and the fifth-youngest all time.
   Third-seeded Madison Brengle of Dover, Del., beat Jamie Loeb of Ossining, N.Y., 6-1, 6-4 in a rematch of last year's final, won by Brengle 6-1, 6-2. Brengle also won the $60,000 Stockton (Calif.) Challenger last October.
   In the doubles quarterfinals on Thursday, Bouzkova and Jill Teichmann of Switzerland crushed Jovana Jaksic, a 25-year-old Serb living in Sacramento, and Lu Jia-Jing of China 6-0, 6-1 in 44 minutes in a clash of unseeded teams.
