Chris Evert and Pam Shriver won their singles matches and teamed in doubles Wednesday at Vancouver, Canada, to lift the United States into the quarterfinals of the Federation Cup tennis championship.
The 3-0 victory over France also assured the United States of a spot in the main draw of the 1988 Olympic Games.
Shriver, forced into singles competition when Martina Navratilova sprained her ankle, defeated Isabelle Demengeot, 6-0, 7-6.
Evert trounced Nathalie Tauziat, 6-1, 6-0, then teamed with Shriver to beat Demengeot and Catherine Suire, 6-1, 6-0.
The victory moved the United States, which has won the Cup 12 times, to the quarterfinals for the 25th consecutive year. The only time the United States failed to advance past the quarterfinals was in 1973 when it lost to West Germany, 3-0.
