Playing career
Leonard Roscoe Tanner was born in Chattanooga, Tennessee, in 1951 and grew up on Lookout Mountain. At Stanford he played No. 1, with Sandy Mayer at No. 2, and the two won the NCAA doubles in 1972. He turned professional that year, and Arthur Ashe asked him to be his doubles partner.
A left-hander with a low toss and a lunging, very fast serve, he was built for grass. He reached the Wimbledon semi-finals in 1975 and 1976, losing to Jimmy Connors and Björn Borg, and in January 1977 won the Australian Open at Kooyong, beating Guillermo Vilas 6-3, 6-3, 6-3. In 1979 he took Borg to five sets in the Wimbledon final and reached a career-high No. 4; two months later he beat Borg in the US Open quarter-finals. He won the Davis Cup with the United States in 1981, 16 singles titles in all, and retired in 1985 after an injury to his serving elbow.
After his playing career he was arrested several times over unpaid child support and bad cheques, and served time in prison, including a year in Florida after his arrest in Germany in 2003.
