Ashes 2015: Derbyshire vs. Australians Day 1 Takeaways

Australia put in another solid performance with the bat on the first day of their tour match against Derbyshire.

Openers Shaun Marsh and David Warner both made centuries before retiring, and Shane Watson delivered a spectacular cameo as the visitors closed on 413 for nine.

The Aussies didn't have it all their own way, though, thanks largely to an impressive debut from 19-year-old Derbyshire seamer Will Davis.

Michael Clarke's scratchy form continued, and Adam Voges and Peter Nevill were both dismissed cheaply.

Read on for the main takeaways from Day 1 in Derby.

Shaun Marsh Stakes Test Claim

With Chris Rogers potentially a doubt for next week's third Test, reserve opener Shaun Marsh showed that he's in fine touch if called upon.

After scoring 114 in the tourists' opening match against Kent, Marsh added another century against Derbyshire.

The 32-year-old was largely untroubled against the inexperienced county attack, eventually retiring with 101 runs to his name from 177 balls.

Younger brother Mitchell fully justified his call-up at Lord's. If Rogers doesn't recover from his dizzy spells, Marsh senior looks like a more-than-capable replacement.

Michael Clarke's Problems Continue

One of the few disappointments for the Australians at Lord's was the form of Michael Clarke. The captain scratched around for seven from 32 balls in the first innings but gave hints of a return to form with a nice second-innings cameo.

Clarke needed some time in the middle in Derby, but his stay was frustratingly brief. The skipper made a stodgy 16 from 37 deliveries before nicking off to debutant Will Davis.

There were few positives for England following the second Test. Clarke's lack of form is one of them. Many more failures and expect the calls for Steve Smith to take over the captaincy to get a little louder.

Remember the Name Will Davis

Resting senior bowlers when the tourists are in town is disappointing for spectators (what, no Mark Footitt?). Leaving out the old sweats gives youngsters an opportunity, though, and Will Davis grabbed his chance with both hands.

Bowling at a decent pace, the 19-year-old picked up the wickets of Michael Clarke and Adam Voges in the afternoon session, then returned after tea to nab Nevill. He finished the day with figures of three for 63 from his 15 overs.

Having the Australian skipper as your maiden first-class wicket is a fine way to mark your debut.

David Warner Carries on Where He Left Off at Lord's

It didn't have any impact on the result at Lord's, but how costly could Adam Lyth's drop of David Warner be for the rest of the series?

After being given a life on nought, Warner smashed a rapid-fire 83 against England in the second innings.

The Aussie opener looked in imperious touch in Derby, smashing 101 from just 108 balls.

Rumours of Warner's frailty against the moving ball in English conditions appear to have been greatly exaggerated.
