Englishman Liam Livingstone has smashed a reported world record 350 from just 138 balls during a club match.
Playing for Nantwich in a National Club Championship match against Caldy, the 21-year-old hit 27 sixes and 34 fours to reach the highest one-day score in any form, the BBC reports.
However Otago club player Callum Egen hit 381 not out in a 40-over game last year.
"From 100 onwards, I was just trying to whack every ball for six," he told BBC Sport.
Nantwich went on to score 579 for 7 before bowling out Caldy for 79 to win by 500 runs.
