Answer
Martina Navratilova defeated Zina Garrison in the 1990 Wimbledon final. Navratilova, a nine-time Wimbledon champion, won the match in straight sets, 6-4, 6-1. Garrison, who was unseeded in the tournament, had upset several higher-ranked players on her way to the final, including Steffi Graf in the semifinals. However, she was unable to overcome Navratilova's experience and power on the grass courts of Wimbledon.
