This will be their first meeting.
Better grass results for Safarova in the last 12 months. She has reached the 4th round at Wimbledon for the last 2 seasons and reached the semis in 2014. Last week she reached the semi final in Nottingham losing out to
Vekic in a third set tie break. She came through a tough 3 setter with Cibulkova in the last round.
Osaka beat Davis in a 3rd set tie break in the last round. That was her first main draw win since April. Her only grass success has been in ITF tournaments with the last being as a finalist in 2015 in Surbiton, UK.
I favour Safarova to take this. Wait for 1.80 before backing.
