Aces high as Karlovic prevails in Australian Open marathon
Croatian sets first-round sets record for games played as he wins opening match with 75 aces against Zeballos in match lasting more than five hours

Ivo Karlovic fired down 75 aces in a record Australian Open marathon against Argentina’s Horacio Zeballos which lasted five hours, 15 minutes and finished in a 6-7 (6-8) 3-6, 7-5, 6-2, 22-20 first-round victory for the Croatian on Tuesday.
The 37-year-old 20th seed threw his hands in the air in delight after Zeballos ballooned an attempted lob high into the night sky to finally bring an end to the gruelling 157-minute fifth set.
Karlovic embraced his exhausted opponent then exchanged high fives with a large part of the crowd which had stuck with the contest from its start in the afternoon sun to the finish under the low wattage lights on the tiny Court 19.
With all the other matches on the outer courts long finished, a carnival atmosphere had developed as the two players tried and failed to break each other’s serve in the final set.
Organisers sent ballboys running off to get more energy drinks as the marathon continued with the gloom punctuated occasionally by fireworks being set off at a match at the neighbouring Melbourne Cricket Ground.
