For years, two tennis players with little in common other than their love for the sport held records that seemed unlikely to be broken.
Kenny Banzer is a 30-year-old wealth planner from Liechtenstein, one of the world’s richest countries. Gadonfin Yaka, 75, is a maintenance man at a post office in Germantown, Md., who grew up in a thatched-roof dwelling in a remote village in Togo with no electricity or running water.
In 2000, Banzer was a seventh grader, five days past his 14th birthday, when he became the youngest player to compete in the Davis Cup.
A year later, Yaka played in the Davis Cup for Togo at 60, setting the record for the oldest Davis Cup participant.
