The reigning world champions chased down a modest target of 230.

 

Steve Smith was the hero for Australia with a sublime 76.

 

The in-form batsman could define Australia's campaign.

 

Here are the key things that folded.

 

Return: Smith's return to the national team has been significant

 

Smith's return to the Australian team after the 12-month ban for a ball-tampering scandal was always going to be closely looked at.

 

Smith has brushed off any insecurity and just focused on his game.

 

The returns have been superb so far.

 

In four warm-up matches, the Aussie star has got scores of 22, 89*, 91* and 76.

 

This augurs well for the defending champions.

 

Smith: Smith masters the chase to show his value

 

Smith holds the key in this Australian batting line-up.

 

He is their best batsman and we all know what he is capable of in the big stage.

 

Smith hit seven fours and two sixes to lead the chase against the Windies.

 

He was involved in two important partnerships that helped Australia in their chase.

 

Shaun Marsh also chipped in with a fluent 55*.

 

Fact: He's ready for a big tournament: Marsh on Smith

 

"It's certainly the best seat in the house, he's going fantastically since he's come back in and it's great to see him come in, score some runs and no doubt he's ready for a big tournament," said Shaun Marsh on Smith as per ESPN.

 

Relief: Aussies breathe a sign of relief regarding Khawaja

 

Aussies were handed a positive news after scans confirmed that Usman Khawaja did not suffer a serious injury after being struck by an Andre Russell delivery.

 

The 32-year-old was forced off the field early in his innings after the ball managed to catch him under the grill on his helmet.

 

He was led from the field by team doctor Richard Saw.

 

Learnings: What did we learn from the warm-up match?

 

Australia managed to dismiss the Windies for 229 in 46.2 overs.

 

Their three premier pacers Pat Cummins (2/36), Mitchell Starc (2/34) and Nathan Coulter-Nile (2/25) excelled with the ball.

 

This will please the Australian camp immensely and boost their confidence further.

 

As for West Indies, they had a few positives to build upon.

 

The understanding will be key as time progresses.
