Jung makes blogs about his experiences and his life as a professional tennis player.[2] He was featured in an article by ESPN subsidiary Grantland – together with fellow Michigan alum Evan King as well as then-upcoming players Frances Tiafoe and William Blumberg) – that displayed the struggles and low prize money in playing on the ITF Futures Tour.[3]
Career
Jung reached his first quarterfinal at the 2018 Hall of Fame Tennis Championships in Newport, Rhode Island. He defeated veteran Nicolas Mahut in the second round, but his run was ended by Tim Smyczek, who outlasted Jung 6–1, 5–7, 6–4 in a nearly two-hour, 185-point quarterfinal match.[4]
His career-best result is a semifinal berth at the 2020 New York Open, where he defeated former champion and world No. 5 Kevin Anderson in the first round,[5] followed by seventh seed Cameron Norrie in the second, before upsetting defending champion and third seed Reilly Opelka in the quarterfinals.
