Australian skipper Michael Clarke scored a sparkling ton against Worcestershire on Day Three of the warm-up in London.

Clarke, who had been suffering from a recurrence of his longstanding back injury during the early stages of the tour, got in touch for next week's first Test against England at Trent Bridge by making 124 off just 98 balls.

His innings featured 16 fours and three sixes, although a placid pitch and a less than threatening attack certainly worked in the star batsman's favour.

Australia set Worcestershire 457 to win, with the hosts 64 for one at stumps – a deficit of 393 after Nick Compton, who on Wednesday revealed his unhappiness at being dropped by England, the man out.

Earlier, Australia declared for the second time in the match after piling up 344 for five, with Phil Hughes making 86.
