If Marti and Sergio are really an item, that raises some questions. How often do the women's tennis tour and the men's golf tour cross paths? Very infrequently, I would think. Are there two separate golf tours, an American one and a European one, and which does Sergio belong to? Would Marti change her training base from Florida to Spain? I see Marti having even less time to be with him than with a boyfriend at her training base, like Calkin, or a boyfriend from the men's tennis tour or some pro team sport, like hockey.
