The 2026 tennis season is poised for intense competition, with Carlos Alcaraz and Jannik Sinner, dubbed 'Sincaraz,' expected to dominate, beginning with the Australian Open. Aryna Sabalenka aims for more Grand Slam success, starting at the Brisbane International. The United Cup also features top players like Iga Swiatek and Alexander Zverev. Sinner, coming off a strong year with an Australian Open and Wimbledon title, feels he has improved, while Alcaraz seeks his first Australian Open title after a split with his coach.
