In the summer of 2015, Croatian tennis player Ivo Karlovic set a record for the most aces struck over the course of a three-set match. Karlovic achieved the feat at the Gerry Weber Open in Halle, Germany. A tune-up for the Wimbledon Championships, the tournament takes place on a quick grass court that plays to the advantage of big servers like Karlovic, who holds a number of additional serving records.
During a quarterfinal match against third seed Tomas Berdych, the 36-year-old Karlovic hit 45 aces over the course of a 7-5, (8)6-7, 6-3 victory that lasted two hours and 12 minutes. In doing so, Karlovic eclipsed his own record of 44 aces--a mark he had shared with Australian Mark Philippoussis--set at his home tournament of Zagreb in 2014. Karlovic lost the subsequent Gerry Weber Open semifinal match to eventual champion Roger Federer in two tiebreak sets
