World No.35 Reilly Opelka recently took a cheeky dig at former World No.1 Andy Roddick

Roddick, who is perhaps best known for his rocket serve, was also known for wearing extremely short socks.

Opelka took to social media to joke that during a recent practice session, a child thought he was Andy Roddick because of his "short socks."

"Some kid saw my short socks and thought I was Andy Roddick," Opelka tweeted.

Opelka, who is known for being outspoken, often takes to social media to vent his frustrations. The Michigan native has been under fire recently, as he continually engages with fans on social media due to his controversial posts and takes on matters surrounding the ATP and WTA.
