World number one Aryna Sabalenka meets Madison Keys in the Brisbane WTA quarter-finals on hard courts on 9 Jan 2026, best-of-three, with live stream and TV details below.
The market points clearly one way, but the most recent chapter in this rivalry went to Keys in a major final, which keeps the stakes sharp. With the 2026 season only just starting, the numbers need a little extra context as well, and this match should show quickly who has found their range.FINISHED

6-3

Sabalenka leads the head-to-head 5-2, yet the last meeting swung Keys' way in the 2025 Australian Open final, where she won 2-1. Their seven matches have averaged 22.7 games, with three deciding sets, so swings of momentum have been part of the pattern. On the serving numbers across the series, Sabalenka has held more often (80% of service games won versus 66%), which is why Keys usually needs her return pressure to land early.

Both players arrive 2-0 on hard courts, but it is a very small slice of the new season and should be read with care. Even so, Sabalenka's early hold and return rates stand out at 94% and 60%, while Keys has posted 82% on serve and 26% on return.
The contrast shows up in match length too, with Sabalenka averaging 10.3 total games per match to Keys' 19.3, hinting at cleaner, quicker control when Sabalenka gets on top.By signing up at bet365, you gain access to one of the most reliable live streaming services available for this match and the rest of the tennis season.

Over their last 10 matches, Sabalenka is 8-2 and has won the opening set 90% of the time, which often lets her dictate the scoreboard rather than chase it. Keys is 4-6 in the same span, and the combination of 6.1 double faults per match and a 27% return-games-won rate leaves less room for error against a top seed. If this turns into a third set, Sabalenka's 67% deciding-set win rate in that stretch also nudges the balance.

Bookmakers price Sabalenka at 1.21 against Keys at 3.78; first-set prices are 1.28 versus 3.19. It is a strong lean, though the season being in its opening week adds a small note of caution to any early read.
Sabalenka's recent profile blends a high hold rate with meaningful return bite, and that combination is usually decisive on hard courts when she lands first strikes behind the serve. Keys has the evidence that she can turn this match-up, and her latest win over Sabalenka in a final underlines how dangerous she can be when the baseline exchanges stay on her terms.
Both have played back-to-back, with Sabalenka logging 3h 57m across her last three matches and Keys 4h 27m, so composure in longer games could matter as much as raw power.Prediction
Aryna Sabalenka
Madison Keys
Overall indicators tilt towards Aryna Sabalenka, led by the market price and the sharper last-10 profile on serve-and-return balance. Madison Keys' win in their most recent meeting keeps this from feeling routine, especially with the season only just underway, but Sabalenka's ability to hold and apply return pressure more consistently on hard courts gives her the clearer path.
