WATCH: Kei Nishikori emulates coach Michel Chang, serves underhand against Lucas Pouille

Japanese tennis star Kei Nishikori pulled off a Nick Kyrgios by serving underarm during an exhibition match against Frenchman Lucas Pouille.
Playing at the Aspall Tennis Classic at the Hurlingham Club, Nishikori was up 6-5 (40-0) when he decided to opt for the unconventional method of serving.
It did catch Pouille by surprise as Nishikori closed out on the set in a fashion his coach Michael Chang would be proud of.
“Kei Kyrgiori,” one person joked on Twitter, while another one added: “Homage to Coach #Chang.”
Notably, Chang had served underarm against Ivan Lendl before going on to win the French Open title back in 1989.
Meanwhile, Nishikori, who has never made it beyond the quarter-finals at Wimbledon, will look to break the jinx this time around when the tournament begins on July 1.
He has been seeded No. 8 in the main draw.
