Elena Rybakina vs. Aryna Sabalenka preview

Sabalenka is appearing in a Grand Slam final for the first time after losing her previous three semifinal appearances. The 24-year-old Belarusian advanced by defeating the unseeded Magda Linette 7-6 (7-1), 6-2 on Thursday in her toughest test in the tournament to date. Sabalenka cruised to straight-set victories in each of her first five matches, losing more than three games in a set only twice.

The fifth-ranked women's player in the world, Sabalenka could have a more difficult time against Rybakina, whose 7-6 (7-4), 6-3 triumph over No. 24 seed Victoria Azarenka was her fourth in a row versus a seeded opponent. The 23-year-old Russian pulled off a huge upset in the fourth round as she knocked off World No. 1 Iga Swiatek in straight sets. Rybakina, who leads all women players with 45 aces, took Sabalenka to three sets in each of their previous three meetings but has yet to record a victory. You can see Onorato's best bets here.
