South Australia's Travis Head has become the first batsman to hit two double-centuries in Australian domestic one-dayers with a record-breaking knock against Queensland.
Head smashed 230 from just 127 balls in an extraordinary innings featuring 28 fours and eight sixes on Wednesday in Adelaide.
The lefthander raced to his 100 from just 65 balls, the fastest-ever ton for SA in the one-day competition.
The Redbacks posted 8-389 from 48 overs in a rain-shortened innings, with opener Jake Weatherald making 97 from 103 balls.
But Weatherald's knock was a sideshow as Head pulverised Queensland's bowlers.
Head logged the second-highest individual score in domestic one-dayers, behind only Darcy Short's 257 for WA against Queensland in 2018.
The Redbacks skipper surpassed Tasmanian Ben Dunk's 229 against the Bulls in 2015 in reaching his second domestic one-day double-ton - he made 202 against WA in 2015.
Short and Dunk are the only other batsmen to have made domestic one-day double-centuries.
Head took just 38 balls to reach his half-century at Karen Rolton Oval - the ground where he made 163 in the drawn Sheffield Shield opener against WA late last month.
The 27-year-old then accelerated, taking another 27 balls to register his ninth domestic one-day century.
Head needed just 26 more balls to race from 100 to 150, yet still improved his scoring rate by moving from 150 to 200 in only 23 deliveries.
