Singapore QFs Set: Eala Falls, Sakkari and Gibson Storm Through

The quarter-final line-up at the 2026 Singapore Tennis Open is confirmed after four round-of-16 matches on Thursday night completed the last-eight draw ahead of Friday's quarter-final session at the OCBC Arena. The biggest news from the evening session was a marathon three-hour-plus upset: unseeded Russian Tatiana Prozorova eliminated third seed Alexandra Eala 4-6, 7-5, 6-3 in one of the week's most dramatic results.

Eala's Run Ends in Three Sets

Philippines star Eala, ranked inside the world's top 20 and seeded third at Singapore's debut WTA 500 event, came into Thursday as one of the tournament favourites. Prozorova, ranked World No. 180 and without a single win over a WTA top-40 player prior to this week, had nothing to lose — and played accordingly. Eala took the first set 6-4 and appeared to be in control, but Prozorova found another gear in the second, winning 7-5 before closing out the decider 6-3 in a result that will reverberate across the Asian tennis circuit. It was described by the WTA as Prozorova's first career win over a top-20 opponent. Prozorova now faces China's Wang Xinyu in the quarter-finals; Wang had earlier beaten Jasmine Garland 7-5, 6-4 in a composed performance that put her firmly in the last eight for the first time at a WTA 500.

Sakkari and Gibson Both Advance

Seventh seed Maria Sakkari delivered one of the cleaner performances of Thursday's session, beating Japan's Nao Hibino 7-5, 6-1 to advance to her first WTA 500 quarter-final of this stretch of the season. After dropping serve once in the first set, Sakkari regained her footing to take it 7-5 and then dominated the second with aggressive returning and consistent groundstrokes. Sakkari meets unseeded Australian Talia Gibson in the quarter-finals. Gibson had to work for it, beating Slovakia's Viktoria Morvayova in two tiebreaks 7-6, 7-6 in a scrappy but hard-earned match. Gibson had already entered Singapore with wind at her back after an earlier walkover and now stands in the last eight of a WTA 500 event for the first time in her career.

The Full Quarter-Final Draw

The quarter-finals on Friday at the OCBC Arena feature four matchups. Top seed Mirra Andreeva, who had powered past Aliaksandra Sasnovich 6-2, 6-2 in the round of 16, opens against wild card Leylah Fernandez in a fifth career meeting. Fourth seed Elise Mertens, who reached the quarter-finals via Barbora Krejčíková's retirement through injury, plays fifth seed Maja Chwalinska. Sakkari versus Gibson and Wang versus Prozorova complete the draw.

What the Quarter-Finals Hinge On

Andreeva has won three of her four career meetings with Fernandez and enters as a strong favourite, but the Canadian remains capable of a surprise on hard courts and earned her wild card with intent. Mertens and Chwalinska are both seeded for a reason, and their match shapes as the day's closest contest — two top-50 players with strong hard-court records who have rarely met at tour level. The Sakkari–Gibson encounter pits a former world No. 3 attempting to reassert her standing against a qualifier showing she belongs at this level. Semi-finals at the Singapore Tennis Open are set for Saturday at the OCBC Arena.
