Martinez, seeded third, stopped an eight-match losing streak against the Swiss teenager with a 7-5, 6-4 victory over the defending champion today to advance to the final of the $1.08 million German Open.

The Spaniard will seek her second title here in theee years and 32nd of her career when she battles 10th seed Amanda Coetzer in Sunday's final. Coetzer reached her first final of the season by defeating unseeded Joannette Kruger, 6-2, 6-4, in an all-South African affair.

Hingis had her 13-match winning streak come to an end and will switch positions with rival Lindsay Davenport for the second straight week in the battle for No. 1. She suffered only her fourth loss in 37 matches this season.

Martinez, 28, has not won a WTA Tour title since Sopot, Poland last year. The former Wimbledon champion reached the semifinals at the Australian Open before losing to Hingis and was runner-up at the Australian Hardcourt Championships in January and the Bausch & Lomb Championships on clay last month at Amelia Island, Florida.

The 28-year-old Coetzer has not appeared in a WTA Tour final since last year at Oklahoma City. The diminutive South African has won six singles titles but none since 1998 at Hilton Head, South Carolina.

First prize at the 93rd German Open is $166,900. Only the U.S. Open (113), Wimbledon (106) and the Canadian Open (100) have been held longer among women's tournaments.
