Ivo Karlovic set a new world record with a 156 mph (251 km/h) serve in Davis Cup World Group first round doubles match against Germany. The previous record of 155 mph (249.4 km/h) was set by Andy Roddick in a Davis Cup semifinal in 2004.
The 6ft 10in Croat hit the monster serve in the fourth set of his doubles tie which he and teammate Ivan Dodig lost 6-3, 3-6, 5-7, 6-3, 6-4 to Germany’s Christopher Kas and Philipp Petzschner.
