🇮🇹 Jannik Sinner — Form & Statistics

World number 1 Jannik Sinner goes into the US Open 2025 semifinals with the superior status, carrying the momentum of 26 major hard-court wins in a row. He holds a 54-5 record for 2025, with titles at the Australian Open and Wimbledon. In New York, only one set was lost by Sinner to Shapovalov, and then it was another easy win, Lorenzo Musetti having gone down by 6-1, 6-4, 6-2 in the quarterfinals. His career total in hard courts stands at 200-50, and in 2025, he is 12-1, with a win percentage of 90. His forehand is an absolute precision shot, and his physicality has improved tremendously; as said by Auger-Aliassime, his serve and movement have augmented. "I am very happy to be in the semis," Sinner said after his win over Musetti, showing a mindset of self-improvement. Following his retirement in the Cincinnati final due to illness, Sinner has been playing at peak form at the US Open, going undefeated 16-0 vs. Italians, including three wins over Musetti. Put this in a clinical curse, and Sinner becomes a juggernaut in the Grand Slam.

🇨🇦 Felix Auger-Aliassime — Form & Statistics

Felix Auger-Aliassime, 25th in the world, has since come roaring back and reached his second Grand Slam semifinal at the US Open 2025. He is 30-15 for the year, but his New York run has been stellar, with wins over Billy Harris, Roman Safiullin, Alexander Zverev, Andrey Rublev, and Alex de Minaur. His 4-6, 7-6(7), 7-5, 7-6(4) quarterfinal victory over de Minaur saw Auger-Aliassime hit 51 winners to 50 unforced errors and showed an aggressive but inconsistent style of play. Those 69 aces in four sets, along with 11 service breaks, underlined the power he was serving with, particularly on his first serve, but the second was found wanting. "I need to play good tennis," Auger-Aliassime said, referring to himself rather than Sinner. Having beaten Sinner twice in 2022 will give him confidence, but the four-hour battle against de Minaur should drain that energy. This Grand Slam run, his best in New York since 2021, places him as a dangerous underdog.
