Many highlighted the shot as a weakness in his game after the match, with Italian tennis legend Paolo Bertolucci claiming Sinner must improve his serve<\/a> if he wants to beat Alcaraz in the future.<\/p>\n

Since then, footage has been leaked of Sinner<\/a> in training, which suggests he may have listened to his countryman.<\/p>\n

Ahead of his trip to China for the beginning of the Asian swing, Sinner has been training in Monte-Carlo.<\/p>\n

The Italian was seen focusing on his serve in training, with one particular clip showing Sinner practising the shot without a racket in hand.<\/p>\n

Such emphasis on the serve can only be good news for fans of the world number two, who raised their concerns over the shot during the US Open.<\/p>\n

Sinner\u2019s serve was far from its best at Flushing Meadows, but was particularly poor in the final, where he trailed Alcaraz in every meaningful statistic.<\/p>\n\nPlayer<\/strong><\/td>\nAces<\/strong><\/td>\nDouble faults<\/strong><\/td>\n1st Serve %<\/strong><\/td>\nWin % on 1st Serve<\/strong><\/td>\nWin % on 2nd Serve<\/strong><\/td>\n<\/tr>\n\nCarlos Alcaraz<\/td>\n10<\/td>\n0<\/td>\n61%<\/td>\n83%<\/td>\n57%<\/td>\n<\/tr>\n\nJannik Sinner<\/td>\n2<\/td>\n4<\/td>\n48%<\/td>\n69%<\/td>\n52%<\/td>\n<\/tr>\n

Working on his serve in training, Sinner has followed in the footsteps of his rival, who did the same thing earlier this year.<\/p>\n

Carlos Alcaraz fixed his serve during the 2024\/2025 off-season<\/p>\n

Ahead of the 2025 season, Alcaraz made a significant change to his serve<\/a>, looking to become more efficient.<\/p>\n

Alcaraz admitted it was taking some time for the adjustments to feel natural before the Australian Open<\/a> began.<\/p>\n

\u201cRight now, I am still thinking about it. I am still reminding myself how I have to do it,\u201d he said.<\/p>\n

\u201cEvery day is getting better and better and feeling better and better with it. We knew I had to change something in the serve to be better at it.\u201d<\/p>\n

The improvements weren\u2019t evident right away, as Alcaraz lost to Novak Djokovic<\/a> in the Australian Open quarterfinals, hitting five double faults in that match, but he was right up to speed by the time the US Open came around.<\/p>\n

Producing arguably the most clinical serving performance of his tennis career, Alcaraz won his sixth Grand Slam title in style.<\/p>\n

Alcaraz and Sinner have both made\/are making changes to their serves in 2025, but where do they rank among the ATP Tour\u2019s<\/a> best over the past 12 months?<\/p>\n
