Brendon McCullum (New Zealand) – 247.61 vs Canada (at Gros Islet on 22nd March 2007)
It was the 18th game of the 2007 ODI World Cup (Group C). While New Zealand top-orders and top-middle-orders shined very well in the first innings of that match, wicketkeeper-batsman Brendon McCullum finished that game in his style. The right-handed no.7-positioned batsman smashed the Cricket World Cup record-breaking 20-ball fifty and remained not out on 52 runs off just 21 balls with the help of only four and 5 sixes. He finished that innings with the amazing batting strike-rate of 247.61.
New Zealand finally managed to score 363/5 (50 overs) in first innings. Later, they won that match by 114 runs after bundling out Canada for 249 runs in 49.2 overs.
