3 100s and 5 50s in 31 ODI innings as Captain.
He captained in 10 ODI series in a row running into the 2017 Champions Trophy after the 2015 World Cup. His contribution towards Pakistan’s win in that tournament can’t be underestimated. Not only his runs with the bat at the top of the innings, but his captaincy in helping Pakistan qualify for that tournament and build some confidence with series wins against Sri Lanka and West Indies under him and also importantly an ODI win in England at Cardiff where they ended up meeting England in the Champions Trophy semi final. Hasan Ali, Babar Azam and Imad Wasim all started and developed under Azhar.
He had a decent ODI record as Captain, winning half of his series and individually having a respectable average and strike rate while leading the ODI side. His removal was harsh. He had a tough schedule as ODI Captain with two series vs England’s strongest ODI team ever that went on to become world champions, a series in Bangladesh against Bangladesh’s strongest ever team and an away ODI series against the teams that played the 2015 World Cup final. Only those were the series he lost as skipper. His ODI record against everybody else and more realistic teams Pakistan could win against was pretty clinical i.e. series wins against West Indies, Sri Lanka, Zimbabwe and Ireland.
The purpose of making him ODI Captain was to groom him as a successor for the longer form of the game.
