Serena leads H2H 9-2.Most recent,Serena won fourth round match at the 2019 AO,Serena winning 6-1,4-6,64 and six months later at Wimbledon Halep won 6-2 6-2.
Serena will be in a physical encounter with Simona,though I have been impressed with Serena's defense,movement especially in her match against Sabalenka.Serena needs to have her first serve at a better percentage than she did in her last match.Serena will step up a gear.Halep will have to display her best tennis to defeat Serena.
