And then there were four.

Semifinal Saturday is set in the desert, featuring a blockbuster lineup that includes two-time champion Carlos Alcaraz, Jannik Sinner, Daniil Medvedev and Alexander Zverev. Will rivals Alcaraz and Sinner prevail to set up their 17th career meeting and third at Indian Wells, or are upsets on the cards in Tennis Paradise?

Undefeated at 16-0 on the season, Alcaraz has proven to be an unsolvable puzzle for his peers on the ATP Tour. He cruised past Cameron Norrie on Thursday night in Stadium 1 to become the third player in history to reach five consecutive Indian Wells semifianals, along with Novak Djokovic and Rafael Nadal.

Next up for the top-ranked Spaniard is two-time finalist Medvedev, who is playing some of the best tennis of his career after emerging from a difficult 2025 season with a new coaching team and a new lease on life. 

The former World No.1 knows he is about to face the game’s most difficult challenge, but believes there is no time like the present to dream big. Medvedev, who lost to Alcaraz in straight sets in the 2023 and 2024 finals, believes the fast desert conditions will give him a better chance against the world-beating Spaniard this time around. 

“I feel like I'm playing great,” Medvedev said on Thursday after dismissing defending champion Jack Draper in straight sets. I never want to jump into conclusions [and say] best tennis of my life or whatever. I'm playing very good. I feel like the court is a bit faster since the two times I have played him. The balls are different. So I feel like it's a good chance to try to show my best tennis against him.”

Alcaraz holds a 6-2 lifetime record against Medvedev, and he has won each of their last four meetings. In addition to his 16-match winning streak, the World No.1 rides a 35-match streak of successive wins on outdoor hard courts. 

A tall order for anyone, even an in-form Medvedev.

Sinner has won his past five meetings with Zverev and dropped just eight games across two comprehensive wins late last year at the Rolex Paris Masters in Paris and the Nitto ATP Finals in Turin.

There is also a key subplot in Sinner’s desert campaign: Trailing Alcaraz by 1600 points in the ATP Race To Turin, the four-time Grand Slam champion risks losing touch with his great rival in the battle for year-end No. 1 honors should the Spaniard win a third title in four years in Tennis Paradise.

Zverev will hope hot conditions add pace and kick to his lethal first serve and that he can pick up a string of cheap points. Sinner will be happy to engage the World No. 4 In extended baseline battles, leveraging his premium movement and defensive skills to win a majority of points that stretch beyond three or four shots.

“It's always a challenge,” Zverev said of playing Sinner, who leads their head to head 6-4. “He's been one of the two best players in the world the last two years. Him and Carlos won all the Grand Slams and all the big events. Of course it's a challenge, but it's a challenge I'm looking forward to.”

Zverev this week became just the fifth man to reach the semifinals of all nine Masters 1000s after dismissing Arthur Fils in the quarterfinals for the loss of just five games. Should he win the title, he will move past Djokovic at No. 3 in the ATP Rankings.

Sinner has his eye on another notable record. Having won Toronto in 2023, Miami, Cincinnati and Shanghai in 2024 and Paris last year, the Italian is looking to complete a sweep of all six hard-court Masters 1000 titles.
