Giorgi won their only previous meeting. That was in Katowice, Poland in April 2016. She won in straight sets on an indoor hard court.
Both players are having great seasons. Ostapenko won the French Open. She is quite inexperienced on grass but has won 3 of her 4 matches on this surface this year. She has needed 3 sets in both her matches. She was priced below 1.20 in both rounds.
Giorgi has also needed 3 sets in both her matches. She was underdog in the last
round against Keys. She lost the opening set against Cornet in the first round and sets 2 and 3 were very tight.
Great value on Giorgi today. Her only weak link is her second serve. She gets aggressive on it and her double fault count can be higher than average. She has hit 19 double faults in her 2 matches.
Lay Ostapenko below 1.50. She starts around 1.70. Three sets looks like likely.
