New South Wales have thrashed Western Australia by 75 runs in the Matador Cup on Saturday.

NSW won the toss and elected to bat, reaching 5-264 from their 50 overs, before bowling WA all out for 189.

The Blues got off to a flying start, with an opening stand of 133 between Nick Maddinson and Ed Cowan.

Maddinson was the first to go, caught Voges, bowled Mitchell Marsh for 74.

Australian captain Steve Smith couldn't back up his brilliant performances in the first two matches, being dismissed for a duck just two balls later.

Shane Watson continued to struggle, as he was stumped off the bowling of Ashton Agar for just 13, to make it 3-168.

Ed Cowan for the next to go, after he notched 100 from 139 balls, to make it 4-223 with five overs to go.

Sean Abott was dismissed for 15, as he went in search of quick runs at the death, while Moises Henriques (43) and Peter Nevill (5) were the not out batsmen.

In reply, Western Australia was in damage control from the outset, losing their first four wickets for just 18 runs, with Bancroft (5), Shaun Marsh (1), Mitchell Marsh (0) and Voges (2) all dismissed within the opening nine overs. Mitchell Starc and Gurinder Sandhu did the damage with the ball, claiming two wickets each in a devastating opening spell.

The Warriors recovered slightly, thanks to a half century from Michale Klinger and contributions from Ashton Agar (31) and Sam Whiteman (45).

However, the damage was done early in the innings and WA was eventually dismissed for 189, 75 runs short of the NSW total.
