Given both players' ability to hold serve and recent first-set trends, the first set is likely to be competitive and exceed 9.5 games.

The read

Liu's momentum and Vandewinkel's tendency to fade after losing the first set give Liu a slight edge to also take the second set.

• Liu has won the second set in 7 of her last 10 matches, including all three Wimbledon qualifying matches.
• Vandewinkel has lost the second set in 4 of her last 6 matches, often after dropping the first set.
• Liu's fitness and recent three-set win over Sakkari suggest she can maintain intensity through two sets.
• Vandewinkel's second-serve win rate (45%) is vulnerable under pressure, which Liu can exploit.

The read

Vandewinkel's high double-fault rate and Liu's moderate rate make it likely that the combined double faults will exceed 7.5, though grass may slightly suppress this.

• Liu averages 4.1 double faults per match (career double-fault rate 4.1%), with several recent matches exceeding 4 double faults.
• Vandewinkel averages 6.3 double faults per match (career double-fault rate 6.3%), with 5 of her last 15 matches having 5+ double faults.
• Combined, their average double faults per match would be around 10.4, but grass can sometimes reduce double faults due to lower bounce.
• Both players have moderate second-serve pressure, which can lead to double faults in tight moments.
