Australia's veteran all-rounder Shane Watson announced his retirement from Test cricket today.34-year-old Watson's 10-year Test career came to an end at the Ashes opener at Cardiff, which England won by 169 runs. Watson made 30 and 19 with the bat, and failed to take a wicket, causing him to lose his place for the rest of the series. Watson's Test retirement was announced on Cricket Australia's official website.Watson, however, hopes to play the shorter formats of the game, one-dayers and T20s. Watson captained his country in one test and nine one-day internationals. He steps down after being ruled out of the rest of the one-day international series by a calf injury sustained in the tourists' victory at Lord's on Saturday. Watson played 59 Tests for Australia, scoring 3,731 runs and taking 75 wickets.Watson's retirement follows Australia Test captain Michael Clarke's move to retire from all forms of cricket in the wake of the Ashes series defeat in England.
