Aaron Finch (Australia) – 18 sixes
Australian captain Aaron Finch also performed impressively in the 2019 ODI World Cup, where the right-handed opening batsman scored 507 runs in 10 innings, with an average of 50.70, including two centuries and three half-centuries.
During that tournament, Finch hit 18 sixes, which was the joint-most sixes for an Australian batsman in a Cricket World Cup edition (Matthew Hayden also hit 18 sixes in the 2007 ODI World Cup). In that tournament, Finch once hit five sixes during the match against Sri Lanka at The Oval on 15th June 2019 (in the League Stage match) where the Australian captain scored 153 runs.
