Welcome to Monday's tennis information session. The Athletic Let me explain the story behind last week's court.
This week saw the first tournaments of 2025 culminate across Australia and New Zealand. Aryna Sabalenka continued her impressive record, with too many matches ending in retirement.

How to beat Aryna Sabalenka in Australia?
At first glance, there is little to offer hope for the rest of the field. World No. 1 Sabalenka enters the Australian Open as a two-time defending champion, winning 27 of 28 hard-court Grand Slam matches and winning her first US Open title in September, along with two majors in Melbourne. obtained.
She also won 27 of her last 28 matches in Australia after clinching the title at the Brisbane International on Sunday, continuing her strong run in a tournament where 10 of the 16 seeded players were eliminated at the first opportunity.
It wasn't as simple as her record in Australia suggests. Sabalenka defeated Mila Andreeva in the semifinals, overcoming a shaky first set to qualify after a tougher match than the 6-3, 6-2 scoreline indicated. Polina Kudermetova 4-6, 6-3, 6-2 in the final. Sabalenka had a pretty tough performance, making 36 unforced errors, but got the job done.
At this stage, she knows she's up against almost everyone. If Sabalenka plays close to her best level, she looks nearly unbeatable on this surface, and the rest of the field is left with either their own perfect performance or Sabalenka's increasingly rare off days. I'm hoping for one.

Why are there so many injury retirements just one week into the season?
The first week of the 2025 tennis season (parts of which took place in 2024) had a very 2021 feel as Riley Opelka and Naomi Osaka reached the finals in Australia and New Zealand, respectively. At the time, Osaka was the dominant female player in the world and Opelka was a top 20 player.
But in the end, 2025 started out feeling like 2024. Opelka has been plagued by hip and wrist injuries and a number of associated complications for the better part of the past two years, having to withdraw from the Brisbane final against Jiri Lehecka in the first set with a back injury, and in the final set against Jiri Lehecka. They lost 4-1 in one set.
Osaka, who fought through many hardships until 2024 and had her season ended early with a lower back injury, won the first set of the final against Clara Thorson before retiring with an abdominal injury.
Neither player wanted to come off their best week in a long time, but with the first Grand Slam of the season just six days away, stopping short of the finish line appears to be the only safe course of action. It looked like. In their post-match comments, both players said, “I'm sorry.”
Although both players seem to have been around forever, they are still relatively young. Osaka, 27, said last year that she was focused on playing for at least five to seven more years. In Auckland, she suggested it had more to do with her ranking than her longevity.
“If I'm not where I think I should be, where I feel like I can be, I want to spend time with my daughter,” she said at a press conference.
Opelka did not have the luxury of thinking long-term like that. The nearly 7-foot-tall frame has its disadvantages when it comes to injury prevention.

“I'm going to spend the next few weeks training seriously and getting stronger physically,” Opelka said after losing in the first round at the US Open in August, early in his comeback.
“The goal is to have a really big offseason in December.”
There was another retirement match that attracted attention. Tomas Machak suddenly missed the United Cup semi-final match against Taylor Fritz. Machak, who led the set 5-2, had two match points on Fritz's serve and serve for the match, but the American broke to make it 4-5 in the set.
During the changeover, Machak exploded, throwing his racket and screaming at his coach. In the next match, Fritz's serving took the match into a third set and he lost 6-5, but he did it again. One point into the match, Machak headed to the net and was pointing and gesturing to the top of his leg for part of the second set, telling Fritz that he was suffering from cramps.
Machak then withdrew from the Adelaide International due to a knee injury, but hoped to be able to play at the Australian Open as well. He is still shrouded in mystery, having spent 2024 looking like one of the world's strongest players, but at times appearing mentally and physically inadequate.

Kei Nishikori's last performance?
When it comes to injuries, no one would begrudge Kei Nishikori the last bloom of his career considering his terrible luck thus far. Now 35, the former world number four knows his best days are behind him, but he remains committed to finding his next big moment.
While staying healthy for a while will feel like enough, Nishikori has suggested he may have a shot at winning his first title in six years. He reached the final of the 250-level Hong Kong Open last week, coming within one set of victory, but ran out of steam in the final against Alexander Muller. Muller won all five matches from a set down. Nishikori lost 2-6, 6-1, 6-3.
His comeback follows his 2014 US Open final opponent Marin Cilic's return from a serious injury of his own to win the Hangzhou Open in September, a month before Nishikori He said this. The Athletic In a Zoom interview, he said that 2025 is the year he wants to strive for better results.
Regarding 2024, he said:I still want to go slowly. I also hope to stay healthy and participate in many games. He added, “I want to be able to play well starting next year.''
Much of the tennis world hopes so, too.

Should I keep the title or not?
Something strange has happened this Australian tennis summer. The 2024 WTA defending champions decided they had little desire to defend their title.
Coco Gauff won in Oakland last year. She played in the United Cup this year. Elena Rybakina wins in Brisbane. She also decided to participate in the United Cup.
Emma Navarro won in Hobart when she was a player competing in the tournament the week before the Grand Slam. Everything was new to me and I needed ranking points wherever I could find them. Given that she is number 8 in the world rankings, she is no longer who she thought she was. She registered for Brisbane, but then became one of a number of seeds to make an early exit, falling to Australia's Kimberly Birrell.
The defeat reverted Navarro to playing in the week before the tournament, with Navarro heading to Adelaide for a point-and-above game. Things went better for Gauff. She played five matches in the United Cup and won all five, the last one against long-time nemesis Iga Swiatek of Poland. That's about the definition of game preparation.
