Seventh seed Maria Sakkari faces Australian Talia Gibson for a place in the Singapore semifinals.
Sakkari has found some rhythm this week. She recovered from 2-4 down in the first set to beat Linda Fruhvirtova 6-4, 6-1, then saw off qualifier Nao Hibino 7-5, 6-1. In both matches she raised her level sharply after a slow start, a pattern she will want to avoid against a hard hitter.
Gibson is into the last eight after beating Fiona Ferro 6-3, 6-3 and lucky loser Viktoria Morvayova 7-6, 7-6. Winning two tiebreaks shows composure, and the Australian's flat, aggressive baseline game can trouble anyone on a quick hard court. A win would give her a first WTA semifinal.
Sakkari's physicality and experience are the edge. She defends well, hits a heavy forehand and has played far bigger matches than this. Gibson will need to serve big and take risks early in rallies to avoid being dragged into a physical contest.
Expect Gibson to make it competitive, but Sakkari should have enough.
**Prediction: Sakkari in three sets. Confidence: medium.**
