Sabalenka vs Alexandrova — the world No. 1 against an awkward problem

Preview · National Bank Open · Round of 16 · Saturday 8 August 2026

Aryna Sabalenka has not dropped a set since arriving in Toronto. Ekaterina Alexandrova is one of the few players on tour who can take the ball as early as she does and has beaten her four times. They open the evening session at 19:00 on Centre Court.

The matchup

Sabalenka is the top seed and world No. 1. Alexandrova is seeded 16 and ranked 19 — worth noting, because the two numbers get confused constantly, and because this is Ekaterina Alexandrova, not Amanda Anisimova, who plays later on the same court.

Sabalenka leads the head-to-head 5-4 and won the most recent meeting, 6-4, 6-4 on grass in Berlin in June. Alexandrova's wins in the series are real, though, and they follow a template: flat, low, first-strike tennis that denies Sabalenka the shoulder-high ball she loves. When the Russian's serve is firing, that plan works. When it is not, the rallies get long, and long rallies against Sabalenka are a losing proposition.

One correction to the record: Sabalenka is not the defending champion here. Victoria Mboko won last year's title in Montréal, beating Naomi Osaka in the final, and Sabalenka was not in that draw at all — she withdrew before it began, citing fatigue. Her most recent run at this event ended in the 2024 quarter-finals in Toronto.

Form & hard courts

Sabalenka has been efficient rather than spectacular: 6-3, 6-3 over the qualifier Moyuka Uchijima, in which she was broken in the opening game and traded breaks through the second set, then 6-3, 6-4 against Shuai Zhang without dropping serve. Zhang is precisely the kind of low-bouncing, redirecting opponent who has troubled her before, and Sabalenka needed one save at 5-4 to finish it.

Alexandrova has done more work. She needed a tie-break to get past Camila Osorio, 6-3, 7-6(4), then went the distance with Talia Gibson, 5-7, 6-1, 6-3, after being broken to lose the opening set. She has been playing well and winning matches she is expected to win, which is the substance of her run this week.

The surface-adjusted numbers are stark. Sabalenka is the No. 1 hard-court Elo on the women's tour; Alexandrova sits outside the top 35. That is not a seeding artefact — it is the widest gap on Saturday's card by a distance.

The deciding factor

Physical state, and this is the concrete reason to side with the favourite rather than the hot hand. On 28 July, in her opening match at the Memphis Classic as top seed, Alexandrova collapsed with heat illness and retired at 5-4 down in the third set to the 16-year-old Kristina Liutova after three hours and eleven minutes. She has recovered well enough to win two matches here, but she has also just spent the best part of two hours getting past an opponent outside the seeds, while Sabalenka has been on and off court inside an hour and a half twice.

The call

Sabalenka. Alexandrova has four wins in this series and the game to make it awkward, so this is not a free pass — but the hard-court ratings, the two straight-sets wins and the difference in workload all point one way. Lean Sabalenka, medium-high confidence.
