ATP Miami Quarterfinals: Sinner, Zverev Advance? Predictions & Previews

As the ATP Miami tournament approaches its final weekend, the draw has presented opportunities for several lower-ranked players to advance. However, any contender on this side of the bracket will likely need to overcome the formidable No. 2 seed, Jannik Sinner, for a chance at the championship. Let's delve into the previews and predictions for today's quarterfinal matchups.

ATP Miami Quarterfinal Predictions

Alexander Zverev vs Francisco Cerundolo

Head-to-Head: Zverev 3-3 Cerundolo

Despite various discussions surrounding Alexander Zverev, he has maintained a consistent presence among the sport's top five players for nearly a decade. This year, he boasts a 14-4 record and stands just one victory shy of reaching the semifinals in both legs of the 2026 Sunshine Double. Yet, his path forward on Thursday promises to be challenging. Meanwhile, Francisco Cerundolo, initially recognized primarily for his prowess on clay, has impressively reached the ATP Miami quarterfinals, poised to achieve a new career-high ranking. He has demonstrated exceptional form this season, rivaling the performance of top contenders like Alcaraz and Sinner, with an 11-4 record since the Australian Open.

Their six previous meetings are evenly split, though Zverev has claimed their last three encounters. Cerundolo, however, did secure two victories against him earlier in 2035. Anticipate intense baseline exchanges characterized by powerful backhand-to-backhand rallies. While a Cerundolo upset, fueled by a supportive Argentine crowd, wouldn't be entirely surprising, I lean towards Zverev as the more probable winner.

Prediction: Zverev in 3 sets

Jannik Sinner vs Frances Tiafoe

Head-to-Head: Sinner 4-1 Tiafoe

Jannik Sinner, currently ranked World No. 2, is within reach of a historic achievement: becoming only the eighth man to complete the coveted Sunshine Double in the same year. Given the favorable progression of the tournament bracket and the Italian's stellar current form, he is clearly the favorite to accomplish this feat. Following a less-than-stellar 2025 season, Frances Tiafoe has shown significant improvement, compiling a 15-7 record to kick off 2026. The 28-year-old American has proven reliable against lower-ranked competitors but holds a less impressive 2-5 record against top 25 opponents. Although one of those victories came in Miami against Mensik, Sinner presents a vastly different caliber of challenge. While Tiafoe might manage to snatch a set, perhaps a 7-6, fueled by the home crowd, a straightforward victory for the Italian appears to be the more probable outcome.

Prediction: Sinner in 2 sets
