Who was McEnroe’s partner in 1977 win?

Today’s question: Tennis anyone? Who did John McEnroe win the mixed doubles with at the French Open in 1977, when he was an 18-year old amateur?

Yesterday’s question and answer: The Kentucky Derby has roses, but what flowers are ceremoniously given to the winner of the second Triple Crown race, the Preakness Stakes? The answer is Black-eyed Susans. The Black-eyed Susan is the state flower of Maryland, where the Preakness is held. The winning horse is actually draped with daisies. They are painted in the center to look like black-eyed Susans, which are not in season in mid-May.
