Alexander Zverev delivered a commanding performance to help Germany secure their opening United Cup victory, dismantling Tallon Griekspoor 7-5, 6-0 in Perth. The world No. 3 found his rhythm after a competitive first set, completely overwhelming his Dutch opponent in a dominant second-set bagel. Meanwhile, Frances Tiafoe and Learner Tien both advanced to the Brisbane International second round with straight-set victories, while Felix Auger-Aliassime helped Canada to their United Cup opener with a routine win over Zhizhen Zhang.
Zverev finds his groove after slow start
The German star needed time to settle into his rhythm against Griekspoor, but once he found his range, the match became a showcase of elite serving and aggressive baseline play. After edging a tight first set 7-5, Zverev completely took control in the second, winning six straight games while dropping just 12 points. The 27-year-old fired 15 aces throughout the match and maintained an exceptional 89% first-serve winning percentage, demonstrating the kind of serving prowess that has made him one of the tour's most dangerous players on hard courts. Most impressively, Zverev saved both break points he faced while converting all four of his opportunities on the Griekspoor serve, showing clinical efficiency in the crucial moments that often define matches at this level.
Tiafoe rolls past Vukic in Brisbane
Frances Tiafoe wasted little time dispatching local wildcard Aleksandar Vukic 6-2, 6-2 in just over an hour of play at the Brisbane International. The American's aggressive return game proved too much for the Australian, as Tiafoe broke serve four times from six opportunities while never facing a break point on his own delivery. With an 82% first-serve winning rate and three aces, the world No. 30 controlled proceedings from start to finish. Tiafoe's dominant performance sets up an intriguing second-round encounter as he looks to build momentum in his first tournament of the new season.
Auger-Aliassime delivers for Canada
Felix Auger-Aliassime helped Canada get off to a winning start at the United Cup with a professional 6-4, 6-4 victory over China's Zhizhen Zhang. The world No. 5 served with authority throughout the match, winning 86% of his first-serve points and firing six aces while never facing a break point. Auger-Aliassime converted both of his break point opportunities to seal the straight-sets win in efficient fashion, giving Canada crucial momentum in their opening tie.
The United Cup action continues with more high-profile matchups scheduled, while Brisbane's first round wraps up with several seeded players still to make their tournament debuts. Tien also advanced in Brisbane with a 7-6(4), 6-3 win over Camilo Ugo Carabelli, converting two of seven break point chances in a solid opening performance.
Monday's marquee matchups
Monday's ATP action promises fireworks as Alexander Zverev faces Hubert Hurkacz in a United Cup showdown between the world No. 3 and the former top-10 star looking to reclaim his ranking. The German leads their hard court head-to-head 2-0, but Hurkacz won their most recent meeting on grass in Halle. Meanwhile, Taylor Fritz aims to snap a three-match losing streak against Jaume Munar, while rising star Jakub Mensik gets another crack at Casper Ruud after beating him at the Australian Open last year.
Zverev looks to assert dominance over struggling Hurkacz

The headline United Cup clash pits Alexander Zverev against Hubert Hurkacz in a match that highlights the contrasting trajectories of both players. Zverev enters on a three-match winning streak and an impressive 31-13 hard court record over the past year, while Hurkacz has managed just 7-7 on the surface during the same period, though his recent 7-3 record in his last 10 matches suggests improved form.
The statistics paint an intriguing picture of two powerful servers with different approaches. Hurkacz has been the more dominant server when he gets his first delivery in play, winning 77.9% of first serve points compared to Zverev's 74.1%. The Pole also leads in aces per match (12.1 to 8.0), but Zverev has proven more reliable under pressure, saving 64.9% of break points faced. Zverev's superior return game could be the difference-maker - he wins 28.7% of points against first serves compared to Hurkacz's 25.7%, a significant gap that could accumulate over the course of the match.
While Zverev leads their overall head-to-head 3-1 and has never lost to Hurkacz on hard courts, the Pole's upset victory in Halle last June proves he has the weapons to trouble the German when firing on all cylinders. Hurkacz's serve-first game plan will need to be executed flawlessly, as Zverev's consistency from the baseline and improved pressure-point conversion (40.0% of break point opportunities) makes him a formidable opponent when matches get tight.
Fritz seeks redemption after rough stretch

Taylor Fritz desperately needs a confidence-boosting victory as he faces Jaume Munar while mired in a three-match losing streak. The American's 4-6 record in his last 10 matches represents a concerning dip in form for a player who compiled an otherwise solid 34-16 hard court record over the past 12 months.
The matchup favors Fritz on paper, particularly given his superior serving statistics. The American fires down 11.7 aces per match compared to Munar's 4.4, and his 78.9% first serve points won percentage significantly outpaces the Spaniard's 71.8%. However, Munar has proven more clinical in break point situations, converting 42.2% of his opportunities compared to Fritz's 36.3%. This efficiency in crucial moments could prove vital, especially given both players' recent struggles - Munar also arrives on a three-match losing streak with a matching 4-6 record in his last 10 outings.
Fritz's main concern will be his tiebreak form, where he's managed just a 17-14 record (54.8%) compared to Munar's poor 3-6 mark (33.3%). If Fritz can leverage his serving advantage to avoid extended rallies and break point scenarios, his power should overwhelm Munar's more grinding style on the hard courts of the United Cup.
Mensik eyes another scalp against Ruud

Jakub Mensik will be brimming with confidence as he faces Casper Ruud again, having defeated the Norwegian at the Australian Open last January. The 19-year-old Czech has been serving bombs over the past year, averaging 14.2 aces per match compared to Ruud's 6.7. However, Ruud's superior consistency shows in his pressure-point numbers, saving 68.9% of break points compared to Mensik's 66.3%. With Ruud in better recent form (7-3 in his last 10) versus Mensik's 6-4, expect a tight encounter that could easily go the distance.
Auger-Aliassime should handle Bergs comfortably

Felix Auger-Aliassime faces Zizou Bergs in what should be a routine victory for the Canadian. Auger-Aliassime's exceptional 30-6 tiebreak record (83.3%) over the past year highlights his mental strength in pressure moments, while his 41-14 hard court record dwarfs Bergs' modest 21-18 mark. The Belgian will need to find ways to disrupt Auger-Aliassime's rhythm early, but the ranking and form differential suggests a straightforward outcome.
Tsitsipas should cruise past Harris

Stefanos Tsitsipas gets a favorable United Cup draw against Billy Harris, whose dismal 1-7 hard court record over the past year tells the story. Harris arrives on a four-match losing streak and has struggled mightily in tiebreaks (1-5 record). While Tsitsipas hasn't been in peak form himself, his superior firepower from the baseline should prove too much for the British qualifier to handle in their first career meeting.
Czech clash headlines Brisbane action

In Brisbane's first round, Jiri Lehecka takes on compatriot Tomas Machac in an intriguing all-Czech battle. Both players enter in poor form - Lehecka on a four-match losing streak, Machac having dropped three straight. The key difference may be Machac's superior break point conversion rate (46.2% vs 39.3%) and his better tiebreak record (9-5 vs 11-11). With both players capable of explosive tennis when confident, this first meeting between the Czechs could swing either way.
Monday's action sets the tone for both tournaments, with several players looking to shake off recent struggles and build momentum for the Australian Open. Upset victories for Hurkacz or Munar would significantly boost their confidence levels, while the favorites will be eager to validate their rankings with convincing performances.
