Australia's bowlers delivered a 64-run win over West Indies in the opening one-day international in St Vincent aftet a stunning collapse from the home side.
Defending 8-204, Australia dismissed the hosts for just 140 at the Arnos Vale Cricket Ground after a calamitous batting collapse by the Windies to take a 1-0 lead in the five-match series.
Left-arm spinner Xavier Doherty (4-49), smashed for three sixes in his first over, rebounded magnificently to claim four quick wickets in his second spell and derail West Indies' run chase.
The hosts had appeared on track to claim a first one-day international win over Australia since 2006 when Dwayne Bravo (32) and Marlon Samuels (35) added 64 for the fourth wicket.
But when Bravo was bowled by Dan Christian (2-12) it sparked a remarkable collapse as the hosts lost six wickets for just seven runs to slump to 9-104.
Doherty was the main beneficiary of the home team's implosion, picking up Samuels and Carlton Baugh (0) in the same over before having Andre Russell (1) stumped by Matthew Wade an over later.
The Tasmania tweaker then completed his good afternoon with the wicket of young spinner Sunil Narine to round off a remarkable collapse by the home team.
Captain Darren Sammy (35) lifted the total with some late hitting but was the last man out as angry home fans chanted "we want Gayle" in a clear statement to selectors to end their feud with explosive opener Chris Gayle and bring him back into the team.
Earlier, Australia's batting was highlighted by a patient 48 on debut by George Bailey, who combined with Christian (18no) to lift Australia's total past 200 on the low and slow pitch.
David Warner (40) and Michael Hussey (32) also chipped in to ensure Australia had what turned out to be an easily defendable score.
Dwayne Bravo was the pick of the West Indies bowlers, taking 3-58 off 10 overs in his first international match for nine months.
Stand-in captain Watson was pleased with the result.
"It's a great way to be able to start the tour and show the guys who haven't played much against the West Indies that if you're able to sustain a bit of pressure for a period of time, we know we can get the results we want," Watson said.
"In the end I suppose it would've been nicer to get a few more runs but it showed that if you're able to bowl well on that wicket there's enough going on there."
The series continues with a second match at the same venue on Monday morning
