UPDATE 2-Cricket-Impressive Hauritz spins Australia to victory

* South Africa suffer heaviest defeat against Australia

* Australia claim 141-run victory

* Mike Hussey hit an unbeaten 83

DURBAN, South Africa, April 3 (Reuters) - Off-spinner Nathan Hauritz snapped up four wickets to steer Australia to an emphatic 141-run victory over South Africa in the first one dayer on Friday.

Hauritz's career-best figures of four for 29 condemned South Africa to their heaviest one-day defeat against Australia as they were skittled out for 145 after just 33.1 overs.

Chasing 287 for victory, South Africa lost their last nine wickets for just 54 runs as Hauritz and medium-pacer James Hopes, who took two for 24, ran through the order.

Australia had earlier posted a total of 286 for seven, with Mike Hussey returning to form with 83 not out.

Hauritz, playing his first match on tour, claimed the key wickets of Graeme Smith (52), Mark Boucher (0) and Albie Morkel (14) in 8.1 overs.
