A full day of a quarterfinal competition at the Indian Wells Masters is set for Thursday, when Jannik Sinner and Alexander Zverev take the court. They are going up against Learner Tien and Arthur Fils, respectively.
(25) Learner Tien vs. (2) Jannik Sinner
It will be a fascinating contrast in styles when Sinner and Tien go head-to-head for the second time in their careers during quarterfinal action at the BNP Paribas Open on Thursday. Can Tien’s consistency and elite tennis IQ get the best of — or at least hang with — Sinner’s offensive firepower? That certainly wasn’t the case when they faced each other in the Beijing final this past fall, when Sinner rolled to the title with a 6-2, 6-2 romp.
Tien has flirted with the exit from Indian Wells multiple times this fortnight. The 20-year-old American needed two tiebreakers against Adam Walton, beat an ill Ben Shelton in three tight sets, and then saved two match points before overcoming Alejandro Davidovich Fokina on Tuesday. Sinner required two tiebreakers of his own against Joao Fonseca in the fourth round, but Fonseca played at an incredible level that probably would have been good enough to defeat anyone other than Sinner or Carlos Alcaraz. Although this should be a lot more competitive than their Beijing contest, the world No. 2 should once again have a significant advantage.
Pick: Sinner in 2
(30) Arthur Fils vs. (4) Alexander Zverev
Zverev and Fils will be squaring off for the seventh time in their careers on Thursday. The matchup has been a fun one, with Zverev leading the head-to-head series 4-2 and four of their encounters having required a final set — including a decisive tiebreaker in the 2024 Hamburg final (won by the Frenchman). Fils also prevailed 3-6, 6-3, 6-4 last spring in Miami, but Zverev won their most recent showdown 7-6(3), 6-1 on the red clay of Rome.
Fils is in resurgent form on the heels of a 2025 back injury. The world No. 32 is 9-3 this season with a runner-up showing in Doha (lost to Alcaraz) and Indian Wells wins over Dino Prizmic, Marton Fucsovics, and Felix Auger-Aliassime. Keep in mind, though, that Frances Tiafoe was also red hot heading into his match against Zverev on Tuesday and the German dominated 6-3, 6-4. Zverev’s tournament also includes a straight-set rout of Matteo Berrettini and a three-set victory over Brandon Nakashima. Even though the world No. 4 has never been past the Indian Wells quarters, conditions in the desert are great for his game. Along with Alcaraz and Sinner, Zverev has been a staple of semifinal lineups at the biggest tournaments in the world in recent years — and that should be the story in the desert.
Pick: Zverev in 2
