Valentin Vacherot began his quest to defend his Shanghai Masters 1000 title with a two-set victory over Sebastian Baez. The match was characterized by powerful serves from both players, with the first seven games featuring a maximum of two points scored by the player receiving the serve. Vacherot eventually gained the upper hand through his consistent play, maintaining the score balance and putting Baez on the defensive. Baez managed to hold his ground for a while, but Vacherot took the lead after securing a crucial ace. The second set started in a similar fashion, with both players making it difficult for their opponents to break their serve. This pattern continued for seven games before Vacherot capitalized on a break point to take the match. In contrast, Baez lost his composure and found himself in a challenging position. After missing two set points, the 53rd-ranked Baez regained his focus and equalized the score at five games all in the third set. However, neither player could separate themselves, leading to a tiebreak. Initially evenly matched, the tiebreak turned in Vacherot’s favor on the sixth point, as he took control on Baez's serve. Despite Baez's efforts, Vacherot waited for his third match point, which came on his own serve, to clinch the match (6-4, 7-6 in 1h27') and advance to the third round. Vacherot will now face Tommy Paul, the 15th seed, who defeated Daniel Vallejo in two straight sets (6-2, 6-2 in 1h17'). The upcoming match promises to be another high-stakes encounter in the prestigious Shanghai Masters 1000 tournament.
