Yes,but I thought Istomin in a sense that he was outside of top 100 at the time.Istomin played great in that match in 2017 but he had been to a few 4th rounds in Slams and been a top 40 player before. It wasn't too much of a shock he was playing that well.
Nobody really expected that level from him against Djokovic in RLA of all places.
Hanfmann was also top 50 player at his peak.
