The Australian Open first round continues on Tuesday with eight compelling matchups, headlined by fifth seed Elena Rybakina taking on Kaja Juvan and ninth seed Madison Keys facing Oleksandra Oliynykova. Former world number one Naomi Osaka returns to Melbourne Park action against Antonia Ruzic, while defending champion Belinda Bencic looks to continue her stellar form against Katie Boulter.
Rybakina aims to start strong against Juvan
Elena Rybakina enters as the clear favorite against Kaja Juvan in their first-round clash, carrying an impressive 74.5% win rate on hard courts over the past year. The Kazakhstani's serve has been particularly dominant, winning 75.5% of first serve points while averaging 7.5 aces per match. Her pressure serving statistics are equally impressive, saving 63.5% of break points faced when the stakes are highest. They met once before at this very tournament in January 2023, with Rybakina advancing comfortably. The world number 5 arrives in outstanding form, posting a 9-1 record in her last 10 matches and showing the kind of consistency that makes her a legitimate title contender in Melbourne. Juvan faces a significant challenge, having played just four hard court matches in the past 12 months with a modest 25% success rate. While her recent overall form shows promise at 6-4 in her last 10 outings, the Slovenian will need to find a way to neutralize Rybakina's powerful serve and aggressive baseline game. Her return statistics show she can be effective against second serves (61% return points won), but breaking down Rybakina's first serve will be the key challenge.
Keys looks to extend strong hard court record
Madison Keys enters her first-round encounter with Oleksandra Oliynykova carrying solid form on hard courts, winning 65.4% of her matches on the surface over the past year. The American's power game translates well to Melbourne's conditions, averaging 4.4 aces per match while winning 65.3% of first serve points. Keys has been particularly effective in tiebreaks, posting a 70% success rate (7-3 record) in decisive sets, which could prove crucial if the match becomes tight. Her serve under pressure has been reliable, saving 57.9% of break points faced, though she'll need to manage her double fault tendency of 5.2 per match. Oliynykova arrives as an unknown quantity on hard courts, with no recorded matches on the surface in the past 12 months according to available data. However, her recent overall form suggests she's playing with confidence, winning eight of her last 10 matches across all surfaces. The Ukrainian will be making her Australian Open debut and will look to use that freedom to play aggressive tennis against the seeded American.
Osaka returns to Melbourne Park
Naomi Osaka makes her highly anticipated return to the Australian Open, facing Antonia Ruzic in their first meeting. The former world number one has shown encouraging signs on hard courts, winning 70.4% of her matches over the past year while averaging 6.2 aces per match. Her tiebreak record of 77.8% demonstrates her big-match experience remains intact. Ruzic brings solid recent form with a 6-4 record in her last 10 matches and has shown she can compete on hard courts with a 50% win rate, but facing Osaka's power and experience presents a different challenge entirely.
Bencic continues hot streak against Boulter
Belinda Bencic brings an 11-match winning streak into her clash with Katie Boulter, having won an impressive 76.3% of her hard court matches over the past year. The Swiss star has been clinical in pressure moments, saving 59.8% of break points while converting 46.6% of her opportunities. They met once before in Tallinn, with Bencic prevailing. Boulter faces an uphill battle, managing just a 29.4% success rate on hard courts recently and struggling with 5.4 double faults per match. Her 49.9% break point save percentage suggests vulnerability against Bencic's consistent returning.
Fernandez faces tricky Tjen test
Leylah Fernandez enters on a concerning three-match losing streak despite solid overall hard court numbers (60.5% win rate). The Canadian's tiebreak expertise (72.7% success rate) could prove decisive against Janice Tjen, who has been impressive in her limited hard court appearances this year. Tjen boasts a 66.7% win rate on the surface and has been even better in tiebreaks at 83.3%. The Indonesian's serve pressure statistics (60.6% break points saved) suggest she won't fold under pressure, making this a potential upset alert for the higher-seeded Fernandez.
Cirstea and Lys renew acquaintance
Sorana Cirstea and Eva Lys meet for just the second time, with Lys having won their only previous encounter in Cluj Napoca back in October 2023. Cirstea brings superior hard court form with a 64.3% win rate compared to Lys's 55.6%, and her serve has been more effective, winning 67.1% of first serve points while averaging four aces per match. Lys faces challenges with her 0-3 tiebreak record and higher double fault rate (4.1 per match), though her slightly better break point conversion rate (51.4%) keeps this competitive.
Siegemund seeks revenge against Samsonova
Laura Siegemund and Liudmila Samsonova have split their four previous meetings 2-2, with Siegemund winning their most recent encounter in Adelaide last year. Both players bring modest hard court form, with Siegemund at 46.2% and Samsonova at 48.1% over the past year. Samsonova's bigger serve (4.6 aces per match) contrasts with Siegemund's superior return game, particularly against second serves where she wins 54.9% of points. The German's 60% tiebreak success rate could prove decisive if the match goes the distance.
Sramkova hopes to upset struggling Ostapenko
Rebecca Sramkova faces Jelena Ostapenko with the Latvian arriving in poor form, having lost six consecutive matches and posting just a 35% win rate on hard courts over the past year. While Ostapenko leads their head-to-head 3-1, including a victory in Rome last year, her current struggles with break point defense (42.5% saved) and excessive double faults (6.1 per match) present opportunities for Sramkova. The Slovak has been more consistent on hard courts and could capitalize if Ostapenko's erratic play continues.
Tuesday's action will set the tone for the tournament's progression, with several seeded players needing strong starts to build momentum. Upsets from players like Tjen or Sramkova could reshape their sections, while the favorites will look to advance without expending too much energy in the Melbourne heat.
