Jannik Sinner has taken his serve to a new level this season.
\n By Andrew Eichenholz<\/p>\n
ATP No. 1 Club member Jim Courier<\/a> told a story on Tennis Channel while commentating on the Miami Open presented by Itau<\/a> semi-final between Jannik Sinner<\/a> and Alexander Zverev<\/a>. The first time Courier met Simone Vagnozzi<\/a>, one of Sinner’s coaches, was four years ago in Miami, he said.<\/p>\n At the time, Sinner had recently parted ways with longtime coach Riccardo Piatti<\/a> and begun working with Vagnozzi. Courier encountered Vagnozzi at the ATP Masters 1000 event and stopped him in the corridor.<\/p>\n “[I] introduced myself and said, ‘What are you going to do with Jannik? What are things you guys would like to work on?'” Courier recalled. “The first thing he said was the serve. He said, ‘The serve, it’s got a hitch in it. We’ve got to get rid of the hitch and we’ve got to smooth it out. I want the toss to be more in front so he can be more offensive with his serve’.”\u00a0<\/p>\n That year, Sinner, who used a platform serve, landed 58.1 per cent of his first serves and won 74.5 per cent of those points. The Italian won 53.2 per cent of his second-serve points and 83.2 per cent of his service games. He made marginal gains in 2023 before making a significant step forward in 2024, maintaining that performance in 2025.<\/p>\n But in 2026, four years on from Courier’s conversation with Vagnozzi, the coach’s work with Sinner has come to the fore. According to an Infosys ATP Beyond The Numbers Analysis, Sinner, who has since moved to a pinpoint serve, has made huge jumps in all key service statistics in 2026 compared to his career numbers, and notable surges compared to 2025, which had been the best serving season of his career.<\/p>\n Sinner’s Serving Stats<\/p>\n \u00a0Service Stat \u00a0First-Serve % \u00a0First-Serve Pts Won % \u00a0Second-Serve Pts Won % \u00a0Aces Per Match \u00a0Service Games Won % Listen To Courier’s New ATP Beyond the Numbers presented by Infosys Podcast<\/a><\/p>\n In 2025, Sinner led the ATP Tour in percentage of first-serve points won (79.5%), second-serve points won (59.1%) and service games won (92%). In 2026, through the Miami semi-finals, he is performing even better in two of those three categories: first-serve points won (67.5%) and service games won (94%).<\/p>\n A big reason why is that Sinner is landing significantly more first serves than he has at any point in his career. Last season, the Italian landed 61.9 per cent of his first serves, his best mark for a year. In 2026, he has made 67.5 per cent of his first serves, an improvement of more than nine per cent.<\/p>\n That is a massive step up for a player of Sinner’s calibre. The 25-time tour-level titlist has already spent 66 weeks as the No. 1 player in the PIF ATP Rankings and is making notable improvements to his game.<\/p>\n
