Carlos Alcaraz vs Reilly Opelka preview

Five-time Major champion Carlos Alcaraz will take on Reilly Opelka in the first round of the US Open 2025.
Alcaraz started the year with a quarterfinal showing at the Australian Open, and then claimed his first indoor hardcourt title in Rotterdam. His title defense at Indian Wells Masters concluded with a semifinal loss to Jack Draper, and he was stunned by David Goffin in the second round of the Miami Open.
That loss to Goffin proved to be a turning point for Alcaraz. He hasn't lost prior to the final of a tournament since then. He won the Monte-Carlo Masters, the Italian Open and the French Open, and was the runner-up at the Barcelona Open during the clay swing. He clinched the Queen's Club title at the start of the grass swing and fell to Jannik Sinner in the Wimbledon final.
Alcaraz continued his good run of form by winning the Cincinnati Open. He was up against Sinner in the final, and unfortunately the match ended with the latter's retirement due to an illness.
A runner-up finish in Brisbane at the start of the year remains Opelka's best result so far. He hasn't advanced beyond the second round of a Major this season. His recent results include third-round appearances at the Canadian Open and the Cincinnati Open.
Carlos Alcaraz vs Reilly Opelka head-to-head
This will be the first meeting between them, so the head-to-head stands at 0-0 for now.

Carlos Alcaraz vs Reilly Opelka prediction

Alcaraz has been in excellent form for the past four months, posting a 39-2 record since the start of April. Opelka, on the other hand, has won 30 matches since the start of the 2024 season.
Opelka has a 4-4 record at the US Open. He recorded his only fourth-round appearance at a Major so far at his home Slam in 2021. Alcaraz claimed his maiden Major title at the US Open 2022 as a 19-year-old, and also captured the No. 1 ranking at the same time.
Alcaraz has a 17-3 record in New York, and lost prior to the quarterfinals for the first time last year. He was upset by Botic van de Zandschulp in the second round in one of the most surprising losses in recent times. It also marks his only loss before the quarterfinal stage of a Major since winning the US Open 2022.
Opelka's serve is his only reliable weapon, with his entire game being centered around it. Alcaraz ranks second on the tour with respect to return points won this year, winning 42.6 percent of points on his opponent's serves. Thus, he shouldn't face too many problems in handling the big-serving Opelka.
Pick: Carlos Alcaraz to win in straight sets.
