Chasing just 26 for victory, the Australians reached 0-26 some 11 minutes before lunch to secure a 1-0 lead in the two-Test series.

But with the scores tied, Usman Khawaja (nine) retired hurt after copping a frightful blow on the helmet from a Shamar Joseph short ball.

Khawaja felt his upper jaw and cheekbone area and was bleeding from the mouth before leaving the field.

Marnus Labuschagne hit the winning run and Steve Smith was unbeaten on 11.

Earlier, Australian paceman Josh Hazlewood completed a five-wicket haul as the tourists were bowled out for 120 earlier.

The West Indies made 188 in their first innings and Australia, with Travis Head making 119, replied with 283.

Australian captain Pat Cummins became just the second skipper in 82 Adelaide Tests to win after sending the opposition in to bat.

Hazlewood followed his 4-41 in the first dig, which included his 250th Test wicket, by claiming 5-35 – the 11th time he has taken five or more wickets in a Test innings.

The West Indies resumed at 6-73 and lost Joshua Da Silva in the fourth over.

Da Silva (18) fell for an Australian trap. With two fielders on the boundary on the leg side, he hooked a short Mitchell Starc (2-46) delivery to Hazlewood at fine leg.

Starc collected his second wicket soon after when Alzarri Joseph (16) wafted outside off stump and edged to wicketkeeper Alex Carey.

Hazlewood secured his latest milestone in the following over, bowling Gudakesh Motie for three – the lefthander didn’t offer a shot and was clean bowled.

West Indies debutant Shamar Joseph, who made 36 batting at No.11 in the first innings and then took five Australian wickets, made 15 from 12 balls before advancing to a Nathan Lyon (2-4) delivery and being stumped.

Cameron Green (1-9) was the other successful bowler while Kirk McKenzie top-scored for the tourists with 26 – he also was their highest scorer in the first innings, making 50.

The second Test starts on January 25 in Brisbane.
