BERN, Switzerland (AP) -- The Swiss Tennis Federation has appointed Steffi Graf's former coach, Heinz Guenthardt, as captain of its Fed Cup team.
Swiss Tennis says Guenthardt will begin his role in a World Group second-tier playoff against Belarus on April 21-22.
Guenthardt replaces Christiane Jolissaint, who stepped down after a 4-1 loss to Australia next month.
Guenthardt coached Graf during the 1990s and helped her win 12 of her 22 Grand Slam singles titles.
Swiss Tennis says Guenthardt, a former doubles specialist, also has worked with current players Ana Ivanovic and Andrea Petkovic.
Switzerland currently has only No. 63 Romina Oprandi in the top 100 of the women's rankings. Oprandi changed her national eligibility from Italy this year.
