Heard the one about the 19-year-old tennis prodigy from Canada, the two-meter-tall Russian and the New York investment banker?

No, it’s not the introduction to a complicated joke, but a real life scenario that linked two of the finalists at the US Open.

Canadian Bianca Andreescu stunned the tennis world by beating 23-time grand slam champion Serena Williams to clinch her maiden major title. A day later, the lanky Daniil Medvedev made Rafael Nadal work hard for his 19th grand slam title.

Connecting the two was 22-year-old financier Michael Genender, who served as a hitting partner for both Andreescu and Medvedev during the tournament.

“I will remember it forever,” Genender told CNN’s Patrick Snell.
