Dancevic won their only previous meeting. That was in the Ilkley Challenger in June 2015. He won in straight sets on grass.
Better results on grass this year for Novikov. Most of his wins on this surface this year were in qualifying rounds. He was comfortable in the last round and won in straight sets.
Dancevic was in the semi finals of this tournament in 2008 and quarter finals in 2010 but since then has not been past the 2nd round. He has done well this week and has come through the qualifying rounds.
I give a slight edge to Novikov here but 3 sets are likely. The sets will certainly be very tight. Wait for 1.85 or better before backing him
