After her French Open victory against Tomanová, Barker felt that it would be the first of a number of Grand Slam titles that she would win, but she would not reach another Grand Slam final in her career. In 1977, Barker won two singles titles in San Francisco and Dallas. She beat Martina Navratilova to reach the Virginia Slims Tour Championships final, where she lost in three sets to Chris Evert. Barker reached the Australian Open semi-final for the second time in 1977 and also reached the Wimbledon semi-final that year. She looked set to meet Virginia Wade in the Wimbledon final in 1977, but unexpectedly lost her semi-final against Betty Stöve of the Netherlands, which denied her the opportunity of playing against Wade in an all-British final. Years later, Barker said that losing to Stöve was the biggest disappointment of her career and admitted that she was so upset at losing in the 1977 Wimbledon semi-final that she could not bear to watch the final, which was won by Wade. After an injury-plagued 1978 during which her ranking dropped to World No. 24, she won three singles titles and reached three other finals in 1979. She was named the tour's "Comeback Player of the Year" by her fellow professionals. Barker reached one final in 1980 and won the last singles title of her career at the Brighton International in 1981, finishing the year ranked World No. 16. She won her last doubles title in 1982 at Cincinnati, and played her last professional match in 1984. Barker won 15 singles titles and 12 doubles titles, posting wins over Chris Evert, Martina Navratilova, Billie Jean King, Evonne Goolagong, Tracy Austin, Virginia Wade, Maria Bueno, Rosemary Casals, Andrea Jaeger and Pam Shriver. In 2004, recalling her French Open win of 1976, Barker said: "I'm still incredibly proud of what I achieved." Upon retiring from tennis Barker became a commentator and sports reporter for Australia's Channel 7 in 1985 before going on to anchor tennis coverage for British Sky Broadcasting in 1990. In 1993, Barker joined the Wimbledon coverage on the BBC and now anchors the two-week-long broadcast for the network. Barker has branched out since joining the BBC, becoming one of their chief sports presenters. She is currently the presenter of the long-running sports quiz show "A Question of Sport", having replaced the late David Coleman in 1997, and was a host of the annual BBC Sports Personality of the Year awards ceremony from 1994 to 2012 before stepping down in 2013.
