That inoffical tournament took place in Saarbrücken, Germany. Lendl filled in for the injured Carl-Uwe Steeb, so Graf and Lendl were a kind of German-American duo. Both won their single matches in the semi-final, so the closing mixed doubles were of no relevance. In the following year Lendl played in the American team together with Mary Joe Fernandez.

Graf - Garrison-Jackson 6-2, 7-5 ; Lendl - McEnroe 4-6, 6-3, 6-4 ; Garrison-Jackson/ McEnroe - Graf/Lendl 9-8
