↑ Frank Falderbaum was drawn against the Spaniard José Guerrero in the first round. Since Adriano Panatta had been banned by the Italian Tennis Association for improper behavior in a Davis Cup game, Falderbaum moved in his place in the draw for the second round and played against István Gulyás. Since Panatta was then obviously able to compete in Hamburg (according to the results overview on the ATP website), the encounter between Falderbaum and Gulyas was apparently downgraded to a first round match. So István Gulyás had to play one more game than he could have expected from the draw (if that's the case). However, he had a bye in the men's doubles.
