Jannik Sinner will kick off his 2026 season on January 10, with a face-off against longtime rival Carlos Alcaraz in a South Korea exhibition match. Opening up about his decision to play Alcaraz right before the Australian Open, the Italian told the Tribune,

"I have never been to South Korea, so I wanted to see for myself what the country is like. It's very interesting for me. Moreover, such exhibition matches are a great opportunity for Carlos (Alcaraz) and me. The fact that we can play in front of Korean tennis fans is something special. Another important reason is the possibility to feel the rhythm of a competitive match at least once before the Australian Open. Getting back the feeling of playing on the court helps a lot in preparing for the season. I took all of this into account and I gladly accepted the invitation.”

Sinner went on to heap praise on the World No.2 and spoke about the uniqueness of each of their matches, adding,

“Alcaraz has almost no weaknesses. He is one of the best players on the tour, and perhaps the best. Matches against him are always huge challenges, but at the same time a pleasure. Each of our encounters is a new story, a new scenario.”

After his exhibition match in South Korea, Jannik Sinner will head to Melbourne for the Australian Open. The Grand Slam begins on January 18 and the 23-year-old will arrive at the tournament as the defending champion.
