The Round of 64 is underway at the Shanghai Rolex Masters, and Friday's slate features a mix of elite seeds navigating their opening assignments against ranked opponents hungry for an upset on hard courts in China. From world No. 2 Carlos Alcaraz to a loaded Medvedev-Struff rivalry, the day promises high-level tennis across the board.

Juan Manuel Cerundolo vs. Carlos Alcaraz - Round of 64

The head-to-head record here is straightforward: Alcaraz leads 1-0, and that lone meeting was not close in overall terms. Alcaraz took that match at the Next Gen ATP Finals in Milan by scores of 4-0, 4-1, 2-4, 4-3(3), controlling the contest before Cerundolo pushed late in the fourth. The ranking gap, world No. 2 versus No. 45, underscores Alcaraz's heavy-favorite status. Cerundolo is a capable and aggressive ball-striker who has earned his place in the top 50, but the prior meeting gave no indication he can trouble Alcaraz consistently. With no odds available and no additional meetings to reference, the data points firmly toward the Spaniard progressing without much alarm.

Prediction: Alcaraz in straight sets.

Camilo Ugo Carabelli vs. Felix Auger-Aliassime - Round of 64

Auger-Aliassime, ranked No. 4 in the world, meets Ugo Carabelli, ranked No. 57, in a Round of 64 contest that their only prior meeting already contextualized clearly. FAA defeated Ugo Carabelli 6-0, 6-3, 6-4 at the French Open on clay, a dominant performance from start to finish that left no ambiguity about the pecking order between these two. Translating that to Shanghai hard courts introduces some variables, but the ranking gap of 53 places and the one-sided H2H record make Auger-Aliassime a comfortable favorite. No odds are listed, but the available data offers little reason to side against the Canadian in this spot.

Prediction: Auger-Aliassime in straight sets.

Daniil Medvedev vs. Jan-Lennard Struff - Round of 64

This is the richest head-to-head in today's Round of 64 slate. Medvedev leads Struff 9-2 overall, and the five most recent results are similarly lopsided: Medvedev has won four of those five meetings, with Struff's lone win coming at Halle in a tight 7-6(6), 6-3 result. Outside of that Halle upset, Medvedev dispatched Struff convincingly in Hamburg, Marseille, Cincinnati, and Wimbledon. The ranking gap, No. 8 versus No. 77, reinforces the scale of Medvedev's historical dominance. Struff has shown he can take a set and, on his best day, steal a match, but the weight of nine wins for Medvedev in eleven meetings makes him a clear favorite. No odds are provided, but the data supports Medvedev comfortably.

Prediction: Medvedev in three sets.

Matteo Arnaldi vs. Taylor Fritz - Round of 64

This Round of 64 clash is the most genuinely balanced matchup of the day on paper. The H2H sits at 1-1, with each player holding a win in their two prior encounters. Arnaldi beat Fritz 6-4, 4-6, 6-3 in Acapulco, while Fritz responded with a tighter 6-3, 6-4 victory in Washington. Both meetings were competitive, and the results suggest Arnaldi is capable of troubling the American. Fritz, ranked No. 9, holds a modest 25-place edge over Arnaldi at No. 34, but the perfectly split record makes this genuinely open. No odds are available to tip the scales further. The two meetings establish a competitive dynamic that could easily produce a third-set decider in Shanghai.

Prediction: Fritz in three sets.

Jiri Lehecka vs. Nuno Borges - Round of 64

Lehecka, ranked No. 12, enters this Round of 64 match as a clear favorite over Borges, ranked No. 50, with the head-to-head record sitting 1-0 in the Czech's favor. That prior meeting came in a Davis Cup rubber, where Lehecka won 6-4, 6-4 in a clean, composed performance. The context of that match, a high-pressure national team setting, suggests Lehecka held his nerve well. A 38-place ranking gap reinforces his status as the favorite here. With only one prior meeting and no odds provided, there is limited data to build a deeper narrative, but what exists points consistently toward Lehecka advancing.

Prediction: Lehecka in straight sets.
