Member of the Swiss Davis Cup Team... An extremely graceful, improvisational player, Gunthardt is a joy to watch... Bob Hewitt, his former coach, described him as having a repertoire of shots and deft touch rivaling John McEnroe's.

Heinz became the first "Lucky Loser" to win a Grand Prix singles title when he upended Harold Solomon to win in Springfield in 1978... Doubles remains his bread and butter... A very intelligent, articulate man, Gunthardt likes to unwind from tennis but not from athletic pursuits; two of his favorite diversions are skiing and wind surfing. Resides in Zurich, Switzerland... Wife, Cecilia; daughter, Anna-Michael.
