Most aces served in an ATP tennis match (best of three sets)

Milos Raonic (Canada; b. Yugoslavia, in what is now Montenegro) delivered 47 unreturnable serves in a three-set, first-round match against Cameron Norrie at the Queen’s Club Championships in West Kensington, London, UK, on 17 June 2024. Raonic advanced 6–7, 6–3, 7–6 after saving two match points. He won 86% of his first-serve points.

Croatia’s Ivo Karlović had set the previous three-set record at 45 aces, fired down during a 7–5, 6–7, 6–3 quarter-final win against Tomáš Berdych at the Gerry Weber Open in Halle, Germany, on 19 June 2015.

John Isner (113) holds the record for the most aces served in a five-set ATP Tour match, namely his epic first-round encounter with Nicolas Mahut at the 2010 Wimbledon Championships.

With 8,445 aces, the 6-ft 5-in-tall (195.6-cm) Raonic is ranked ninth on the ATP Tour for the most career aces served.
