Melbourne: Australia wicketkeeper Brad Haddin announced his retirement from international Twenty20 cricket on Thursday to focus on the longer forms of the game.

Haddin, 33, played in 25 T20 internationals, his last during Australia's just-completed tour of Sri Lanka.

"I thoroughly enjoy Twenty20 cricket and have taken great pride from playing all three forms of the game for Australia," he was quoted in a Cricket Australia statement. "However I feel the time is now right for me to concentrate on Test and ODI cricket.

"This decision has been made to prolong my effectiveness in these formats and provide me further time to prepare for the demands of ODI and Test cricket," he said. "I remain extremely determined to play cricket for Australia and believe this decision will help achieve this."

Haddin has scored 1,995 runs from his 35 Test matches at an average of 37.64. He has 2,466 runs from 90 one-dayers at 32.01.

Despite retiring from international T20s, Haddin will remain captain of the Sydney Sixers in the domestic T20 Big Bash League and the Indian Premier League's Kolkata Night Riders.
