Mitchell Starc's below-par return in the one-day series with England has seen him relinquish his hold on the No.1 ODI bowler ranking spot.
Starc first rose to the world No.1 spot after the World Cup semi-final against India and was named man of the series for the global 50-over tournament as Australia secured a fifth title.
His return of just five wickets from the four matches he played, with an average above 42 and an economy rate nudging six per over, saw him slip behind South Africa spinner Imran Tahir on the ICC's individual player rankings.
Starc had been battling a long-term ankle injury and missed the fourth ODI after having a cortisone injection to help manage his pain.

Opening batsman Aaron Finch, who was a late call-up to an Australian side hit by injury, climbed back into the top 10 ODI batsmen but there was otherwise little movement at the top end of the rankings table from either side.
However, there were still big gains to be had from several Australians, perhaps signalling the start of a climb towards the top of the individual rankings tree.

Allrounder Mitchell Marsh, named the man of the series in Australia's 3-2 victory, jumped 16 places in the batsmen rankings, and 27 in the bowlers category to land on spots 65 and 99 respectively.
Tearaway quick Pat Cummins, who was the series' leading wicket-taker with 12 at 19.66, climbed an incredible 50 spots and is now ranked 62.
Glenn Maxwell's all-round effort saw him climb into the top five of the allrounder's category headed by Bangladesh's Shakib Al Hasan, but the Victorian also jumped 22 spots in the bowlers table to 49 and held steady as the No.9 ranked ODI batsman.
Quick Single: Players shaken by Morgan helmet blow
For England, skipper Eoin Morgan finished just outside the top 20 batsmen after a jump of 11 places while Moeen Ali's off-spin helped him move up 17 spots to 29 on the bowler rankings.
There was no change in the team ranking positions, with Australia still well clear at the top of the tree with England still ranked sixth in the 50-over format, although the hosts did close the gap on fifth-ranked Sri lanka.
