Ivo Karlovic has made history at the Australian Open hitting 75 aces in his First Round win against Horacio Zeballos.
The Croatian won the five-hour epic 22-20 in the final set making it the longest final set in the history of the year's opening Grand Slam. Karlovic's record smashes the previous best, set by Joachim Johansson in his four-set loss to Andre Agassi in 2005.
No player has ever hit more aces in their career than the 37-year-old, but he does not hold the single-game record. In 2010, John Isner hit 113 aces against Nicolas Mahut in their marathon match at Wimbledon. The Frenchman hit 103 aces despite losing 70-68 in the final set.
