Michael Clarke will retire from ODI cricket after Sunday’s World Cup final.

Clarke announced the news in Saturday’s pre-match press conference, revealing the trans-Tasman decider will be his final ODI.

Clarke suggested he only reached closure on the decision “about 48 hours ago” when he returned home from the semi-final against India in Sydney.

“I think I got back to my house at about 12.30. Kyly was in bed and that’s when I spoke to her about it,” he said.

“I know I’ve made the right decision.

“I told my teammates 10 minutes ago. I told the selectors and (Cricket Australia boss) James Sutherland about an hour ago.”

The 33-year-old will continue to play Test cricket.

“I’m hopeful it will prolong my Test career and that’s a priority for me,” Clarke said.

“I don’t feel bad about saying I feel that Test cricket is the toughest part of our game.

“I love that challenge.

“I see it as the pinnacle … I feel like I’ve still got a lot to offer the Australian Test team as captain.”

Steve Smith is yet to be confirmed as Clarke’s successor, but given the 25-year-old filled in as Clarke’s understudy during the Test series it’s expected to happen soon.

“Smithy has certainly matured as a player and a person,” Clarke said.

“I don’t think it would be fair for me to go into who is going to be the next captain, it’s not my place. It’s up to the selectors.”

Clarke noted once he realised he wouldn’t be playing in the 2019 World Cup it was an easy decision.

“There’s no doubt I could keep playing for the next couple of years,” he said.

“But the team and the next captain deserves the time and preparation (to lead for a long time before the 2019 World Cup).”
