His career-best result is a semifinal berth at the 2020 New York Open, where he defeated former world number 5 Kevin Anderson in the first round, followed by 7th seed Cameron Norrie in the second before upsetting defending champion and 3rd seed Reilly Opelka in the quarterfinals. He was eliminated in the semifinals by Italian veteran Andreas Seppi in straight sets.
