All top seeds have been eliminated during the first part of the day at the Shanghai Masters 1000, except for Taylor Fritz, who won in two sets. Five days after his disqualification in the semifinals of the ATP 500 in Beijing, Daniil Medvedev returned to competition in the second round of the Shanghai Masters 1000. Although he had to fight for 1 hour and 52 minutes, the world number 5 eventually eliminated the world number 59, Jan-Lennard Struff, with a score of 4-6, 6-3, 6-3. The Russian served 21 aces during this match, which did not prevent him from losing the first set, due to a break at 4-4. However, he recovered well, winning the second set by breaking the German's serve at 5-4. In the third set, Medvedev managed the break at 3-2, which led him to victory. He will face Dalibor Svrcina, who caused a surprise by defeating the top seed number 28 Tomas Etcheverry (6-3, 3-6, 7-5 in 2 hours and 52 minutes in a match with seven breaks). Felix Auger-Aliassime also needed three sets, and it was even more difficult for the world number 4, facing the 77th Camilo Ugo Carabelli. The Canadian, who served 14 aces, indeed fought for three hours before winning 4-6, 7-6, 7-5, in a match where each player lost their serve twice. The Argentine won the first set by breaking the opponent's serve at 3-3, then came back from 0-3 to 5-5 in the second, before being defeated by "FAA" in the decisive game (7-1). Finally, the world number 4 won by breaking at the best moment, at 5-5 in the last set. Eliminated at the start in Tokyo, the world number 13 Rafael Jodar recovered by eliminating Thiago Agustin Tirante (54th) this Saturday, but it was not an easy win, as he needed two hours to win 4-6, 6-2, 6-3. The Spaniard lost his serve at the start of the match and could not make up for it. However, he recovered well in the next two sets, winning the second thanks to breaks at 2-1 and 5-2, and the third by breaking the Argentine's serve at 4-3. He will face the world number 19 Jiri Lehecka, who also won in three sets against Nuno Borges: 6-3, 3-6, 6-3 in 1 hour and 59 minutes. A break at 1-0 allowed the Czech to win the first set, but the Portuguese equalized one set each by breaking at 3-2 in the second. Finally, Lehecka made the difference at the start of the third, quickly leading 3-0, before concluding on his third match point. Finally, the only top seed to have won relatively easily at the start of the day was the world number 12 Taylor Fritz. Defeated at the start in Tokyo, the American defeated Matteo Arnaldi (38th) with a score of 7-5, 6-4 in 1 hour and 43 minutes. Fritz served 9 aces and lost his serve only once. He won the first set by breaking at 5-5, then saw the Italian catch up to 2-2 in the second set, although he had broken him. After another break at 3-3, the American found himself down 0-40 when serving for the match, but he converted five points to win this match.
