MELBOURNE, Australia — First, a confession: I still wear my cap backward when I play tennis, even at a certain age.
So I come subjectively to this subject as I note that many years after the Swedish pro Mikael Pernfors inspired some of my generation of hackers to reverse our caps, and years after Australia’s Lleyton Hewitt made it definitively a thing in tennis, members of the new wave have acquired the taste, too.
They include the American Jack Sock, Lucas Pouille of France, Karen Khachanov of Russia and the flashy Canadian teenager Denis Shapovalov.
It has never been an entirely logical choice.
