Yet another Test match and yet another dominating performance by Australia. Leading 2-0 up in the series, the hosts needed just three days to beat England at the Melbourne Cricket Ground by an innings and 14 runs to retain the Ashes on Tuesday morning. Starting the day on 31/4, Australia needed just a little more than 15 overs to bowl out England for 68 in the second innings. Scott Boland, who took two English wickets on Monday, added another four to his tally today to finish with figures 6/7 in just four overs to blow away the opposition on his debut. Mitchell Starc took three wickets. For England, they need to get back to the drawing board and do whatever they can to come back stronger in the final two Test matches. Earlier, Australia had won in Brisbane and Adelaide. Get here highlights of AUS vs ENG Boxing Day Test.
