Neither the pioneer nor the present-day popularizer of the underhand serve has been in Paris this year during the French Open.
Michael Chang, who won the tournament with a clutch use of the serve in 1989, is back in the United States, spending time with his wife, Amber, and their three young children. Nick Kyrgios is back in Australia, spending time on social media as a freelance tennis critic, which should make for some testy conversations with his peers when he finally does return to the circuit in person.
