“To win the biggest tournaments in the world, you have to beat the best. And Jannik is the best in the world right now.”

Alexander Zverev arrives at Sunday’s Mutua Madrid Open final chasing a win he has not managed since the 2023 US Open. The No. 2 seed reached his first title match of the season on Manolo Santana Stadium by ending Alexander Blockx’s strong run and snapping a six-match losing streak in 1000-level semifinals.

Zverev’s week included a 6-1, 6-4 victory over Flavio Cobolli earlier in the draw, and he carried that momentum into the match with Blockx. While Blockx saved a pair of break points to hold for 5-4 in the second set, Zverev broke the next time he had the chance and closed out a 6-2, 7-5 win.

As a two-time former champion in Madrid with nine career clay-court titles, Zverev will try to halt a remarkable run by Jannik Sinner. Sinner comes into the final on a 22-match win streak and is attempting to become the first man ever to win five consecutive ATP Masters 1000 trophies since the series began in 1990.

In the victories that brought Sinner to his first Madrid final, he defeated Zverev in the semifinal rounds of 2025 Paris and the first three 2026 Masters 1000 events in Indian Wells, Miami and Monte Carlo. That sequence has left Zverev without a win over Sinner since that 2023 major, and Sinner has run off eight straight victories against Zverev following a four-match swing in the German’s favor earlier in their rivalry. Their last 12 sets have been swept by the four-time major champion.

“Generally, I’m feeling well. I look forward to the final,” Zverev said. He acknowledged the scale of the task ahead: “He’s world No. 1, and hasn’t lost a match since beginning of February. Right now he’s definitely the best player in the world,” Zverev said in his press conference. “I have to play very, very good tennis to have a chance. But I know I’m capable of doing that, and I will try to do my best on Sunday.”

Kei Nishikori announced he will retire at the end of the 2026 season in posts to his social media channels on Thursday. The 36-year-old, currently ranked No. 464, turned professional 20 years ago and will close a career that set new benchmarks for Japanese tennis.

At his peak, Nishikori was the first Japanese man to reach a Grand Slam singles final at the 2014 US Open and rose to a career-high No. 4 less than a year later. He won Japan’s first tennis medal in 96 years when he took bronze at the 2016 Rio Olympics and last year became the first player from his country to surpass 450 ATP match wins. Nishikori collected 12 titles and earned more than $26 million in prize money, and was credited, along with Li Na, with helping to build the sport’s popularity in Asia.

Injuries interrupted much of his later years. Major problems to his hip, wrist, back, shoulder and knees led him to say last year that he “barely hanging on” physically. In his social media statement he reflected on his lifelong drive: “Since I was a child, I have been passionate about tennis, and I have continued to pursue it with only one dream in my heart: ‘I want to compete on the world stage,’” he wrote. “Reaching the ATP Tour, playing at the highest level of competition, and maintaining a presence in the Top 10 is something I am extremely proud of. Whether in victory or defeat, the special atmosphere I felt in packed arenas is irreplaceable.”

He admitted he “still wish[ed he] could continue” but added he could “proudly say that [he] gave it [his] all.” “I am truly happy to have walked this path,” he wrote.

In posts after the announcement, Naomi Osaka hailed her compatriot as “inspirational” and noted their shared milestone at the 2018 US Open, when both reached the semifinals, the first time a Japanese man and woman had advanced that far in the singles draws of the same Grand Slam tournament.

Jannik Sinner advanced to his first Madrid final by defeating Arthur Fils 6-2, 6-4 in the semifinals of the Mutua Madrid Open. The straight-sets victory closed the only gap in Sinner’s Masters 1000 résumé: Madrid had been the sole tournament at that level where he had not yet reached a final.

The world No. 1 has now reached the final at all nine Masters 1000 events. At 24 years old, Sinner is the youngest player to complete that career set since the Masters 1000 tier was established in 1990. He becomes the fourth player overall to achieve the feat, following the members of the Big 3.

The Madrid semifinal also represented another milestone. The win over Fils marked Sinner’s 350th tour-level victory. Born in 2001, he is the first man born in the 2000s — and the first since 1999 — to reach 350 tour wins.

Sinner’s record at Masters 1000 events now stands at 116-29, an exact 80.0 percent winning percentage. That places him alongside two of the sport’s best as the only men in Masters 1000 history with an 80.0 percent or higher winning rate, after Nadal (82.0 percent) and Djokovic (81.4 percent).

The Madrid result combines two forms of career progress: a long-missing final at a single Masters site and the accumulation of consistent success across the tour. Both milestones underline the rapid ascent and sustained performance that have characterized Sinner’s career to date. With the Madrid final now secured, the focus will shift to whether he can convert this latest run into another title at a Premier Masters event.
