Dolgopolov's play is like something from another era - although that's not proving a bad thing.
He loves to mix it up, often using drop shots and the slice to frustrate opponents.
They are tactics which have served him well - and proved popular with fans - for he is now very much part of the top 20.
He first sprang to prominence with a run to the quarter-finals of last year's Australian Open but has refused to go away since.
You will often find the suffix 'junior' after his name as his father of the same name was also a professional player.
