This will be their first meeting.
Good win for Kozlov against Nishioka in the last round. He is inexperienced on grass. He has only played 8 matches on this surface and won 4 of them.
Johnson hasn’t been in good form recently and his record on grass isn’t amazing. If his serve is working well then he should be tough to beat on grass but he loses concentration too often in big moments.
I think Kozlov could make a match of this. It could go to 3 sets. Value on him at the start. Johnson’s experience should be too much for him in the end.
