Kathleen Horvath

Erica Kathleen "Kathy" Horvath (born August 25, 1965) is a retired American professional tennis player.

She was the youngest player to play in the US Open in 1979 at 14y5d—this record still stands. Horvath was the youngest player to win the U.S. National 16 and under in 1979. She also is the only player to ever win all four age groups in the U.S. Girls Clay Courts in all consecutive years.

Horvath played on the WTA Tour from 1981 to 1989, winning six singles titles and reaching a career high rank of #10 in 1984. She reached the quarterfinals at the French Open in 1983 and 1984. She retired with a 176–154 singles record.

Horvath was the only player to defeat Martina Navratilova in the 1983 season (at the 1983 French Open), winning in the fourth round 6–4, 0–6, 6–3. Navratilova's coaches (Renee Richards and Nancy Lieberman) argued in the stands over strategy, something Navratilova noticed during the match.

Horvath had career victories over Navratilova, Andrea Jaeger, Manuela Maleeva, Gabriela Sabatini, Dianne Fromholtz, Claudia Kohde-Kilsch, Mary Joe Fernández, Betty Stöve, and Sylvia Hanika. She was a member of the 1984 US Fed Cup Team. She played in the 1984 Olympics when tennis was reintroduced and was the 1st seed. She was coached by renowned Australian coaches Harry Hopman and Nick Bollettieri.

After her tennis career she got her BS and MBA at the Wharton School of Business and then worked on Wall Street until 2003.
