Top quality second set between Khachanov and and Tsitsipas; TB had to decide (a really good tB with a lot of high-quality rallies and points). Khachanov had two SP at 6-4 and another at 8-7, But Stefanos won The TB (10-8) and the match.
With guys like this, ATP is in safe hands in a post-Federer&Nadal era.
