Australia pace bowler Nathan Bracken retires

Former Australia pace bowler Nathan Bracken announced his retirement from cricket on Saturday due to a persistent knee injury.

The 33-year-old left-armer announced his retirement on his Twitter page on Saturday before he addressed reporters in Sydney.

Bracken, at one stage ranked the world's best One-day bowler, captured 174 wickets in 116 One-day Internationals at 24.36 and was a member of Australia's World Cup winning squad in 2007.

He was less successful in Tests, playing just five games, taking 12 wickets at 42, with his last match against South Africa in Perth in late 2005.
