Australia captain Michael Clarke fell cheaply to teenage debutant Will Davis after David Warner made a hundred on the first day of the tour match against Derbyshire at Derby on Thursday.
At tea, Australia were 253 for three with opener Shaun Marsh 93 not out and younger brother Mitchell Marsh 16 not out.
The 19-year-old Davis, who took two wickets in three balls to dismiss both Clarke and Adam Voges, had tea figures of two for 32 in 11 overs.
It was a decent fight back by the Second Division side after Australia had reached lunch on 132 without loss.
However, they were assisted by left-hander Warner -- 87 not out at lunch -- retiring out as soon as he had completed his hundred.
Warner, who made 83 in the second innings Australia's crushing 405-run win in the second Test against England at Lord's on Sunday, which levelled the five-match Ashes series at 1-1, was rarely troubled after Clarke won the toss.
His one awkward moment came shortly after he had completed his fifty when Davis struck him in the groin.
But, after receiving some on-field attention, Warner batted on and shortly before lunch lofted off-spinner Scott Elstone for six.
Warner went to his hundred with a cover-driven boundary off Jonathan Clare and then walked off, having faced 108 balls including 13 fours and a six.
New batsman Clarke did not look especially comfortable in a 37-ball innings.
Clarke, whose best score of the tour thus far was 56 in the opening match against Kent, was keen to play a long innings in Derby.
But on Thursday, with his footwork uncertain, he edged the lively Davis to Tom Knight in the slips for 16.
And two balls later, Davis had a second first-class wicket when Voges was lbw.
Shaun Marsh is in line to replace Chris Rogers, should the veteran opener be ruled out of next week's third Test at Edgbaston.
Rogers succumbed to a sudden bout of dizziness at Lord's on Sunday.
It had been thought the 37-year-old was a victim of delayed concussion, having been struck on the helmet by a bouncer from England paceman James Anderson on Friday's second day at Lord's.
But Cricket Australia said Wednesday that, following examination by a London-based specialist, Rogers was suffering a balance problem in the inner ear.
The first innings at Lord's saw Rogers score a Test-best 173.
Rogers, who is to have further tests in London, was not scheduled to play against Derbyshire in any event.
Australia included both their wicket-keepers, Brad Haddin and Peter Nevill in the XI to play Derbyshire.
First-choice gloveman Haddin didn't play at Lord's after withdrawing because of “family reasons”, with Nevill impressing on his Test debut.
Both players are set to share wicket-keeping duties in this match ahead of the third Test, which starts on July 29.
Australia's team at Derby also included Pat Cummins -- the injury-prone fast bowler appearing in his first-class match in two years. – AFP
