While a student at
Stevenson High School, Jaeger was the top-ranked player in the United States in the 18-and-under age group. She won 13 U.S. national junior titles, including the most prominent junior titles in tennis: the
1979 Orange Bowl and 1979 Boca Raton. In 1980 (at the age of 15 years, 19 days), Jaeger became the youngest player ever to be seeded at
Wimbledon, a record that was broken by
Jennifer Capriati in 1990. After defeating former champion
Virginia Wade, she became the youngest quarterfinalist in the history of the tournament. Later in the year, she became the youngest semifinalist in
US Open history. By the age of 16, she had become the second ranked female professional tennis player in the world. Jaeger became a household name on the front pages of news publications, notable magazines and appearances on TV.
People Magazine,
Sports Illustrated,
Life Magazine visited her junior high and high school. One of her endorsement commercials featured Jaeger with
Bjorn Borg and another with her Mom, highlighting a new way of viewing sports prodigies. At the
French Open in 1982, Jaeger defeated
Chris Evert in the semifinal 6–3, 6–1 but lost the final to
Martina Navratilova. She then reached the semifinals of both the US Open and the
Australian Open, losing both matches to Evert in straight sets. Jaeger and Evert met 10 times in all in 1982, with Jaeger winning three of the first five but losing the last five in a row. At
Wimbledon in 1983, Jaeger defeated six-time Wimbledon singles champion
Billie Jean King 6–1, 6–1 in a semifinal on
Centre Court, which was King's last career singles match at that tournament and her most lopsided singles defeat at Wimbledon. Jaeger then lost the final to Navratilova. Jaeger won eight of the nine singles matches she played for the U.S. in
Fed Cup. She also won two of the three
Wightman Cup singles matches she played for the U.S., resulting in the U.S. winning Fed Cup and Wightman Cup trophies. A major shoulder injury at the age of 19 ended Jaeger's career in 1985. Jaeger obtained a degree in
theology and ministry training. During her career, Jaeger won
U.S. $1.4 million in prize money and had endorsement deals with clothing, racket, shoes, watch and fast food restaurants. ==Philanthropy==
