Hasn't Alcaraz always been so beatable in the majors that he's won?
At the 2022 US Open, Alcaraz saved a match point against Sinner in the quarter final in the fourth set, went 5 sets against Tiafoe in the semi final, and then won a close 4-setter against Ruud in the final
At 2023 Wimbledon, the momentum of the final against Djokovic was very back and forth. Djokovic had set point for a 2-0 sets lead. Alcaraz won 1-6, 7-6, 6-1, 3-6, 6-4
At the 2024 French Open, Alcaraz beat Sinner in 5 sets (far less intense than the 2025 final though) and had to come from 1-2 down in sets to beat Zverev in the final
At 2024 Wimbledon, Alcaraz had to come from 1-2 down in sets against Tiafoe in the third round, and was pushed to 4 sets in his fourth round, quarter final and semi final. The final was very impressive though, beating Djokovic in straight sets
At the 2025 French Open, Sinner looks invincible until Djokovic pushed him a bit in the semi final, while Alcaraz drops sets to Marozsan, Dzumhur, Shelton and Musetti. Then that final win against Sinner from 4-6, 6-7, 3-5 and 3 CPs down.
