New South Wales 331 (Patterson 66, Henriques 54, Konstas 40, Breadman 3-48, Jackson 3-64) beat Western Australia 244 (Whiteman 52, Bancroft 48, Agar 44, Abbott 3-28) by 87 runs

Western Australia teenager Albert Esterhuysen gave Sam Konstas an almighty send-off but it was New South Wales who had the last laugh in the One-Day Cup clash at the WACA Ground.

Esterhuysen, playing just his second one-dayer for Western Australia, bowled Konstas for 40 and then unleashed an extended roar and stare-down in the Test opener's direction during an emotional celebration.

Konstas entered Thursday's match desperate for a big score to mount a solid case for an Ashes call-up, but he couldn't go on with the job after a strong start.

Half-centuries to Kurtis Patterson (66 in 71 balls) and Moises Henriques (54 in 66) lifted New South Wales to a formidable 331. In reply, Western Australia were bowled out for 244 in 46.5 overs, with the returning Mitchell Marsh making just 2 as New South Wales cruised to an 87-run bonus-point victory.

The result left Western Australia nursing a 1-2 record, while New South Wales (2-1) moved into second spot, behind unbeaten Tasmania (3-0).

Western Australia's innings never got going, despite boasting a stacked batting line-up that had Cameron Bancroft batting at No. 7.

Marsh, who came in fresh off his unbeaten 103 in Australia's T20I victory over New Zealand, was out in just the third over when he was caught on the boundary slashing at a wide Sean Abbott (3 for 28) delivery.

Joel Curtis (15), Sam Fanning (8) and Cooper Connolly (5) all came and went as Western Australia crashed to 45 for 4 in the tenth over.

Sam Whiteman received a huge life on 2 when he was caught at slip - only for Jack Edwards' delivery to be deemed a front-foot no-ball. Whiteman went on to make 52 off 56 balls, but his departure in the 24th over at the hands of Tanveer Sangha was a bitter blow to Western Australia's victory hopes.

Bancroft (48), Ashton Agar (44) and Aaron Hardie (37) all produced handy knocks, but with the required run-rate soaring out of control, Western Australia were never truly in the hunt following the top-order collapse.

Earlier, Konstas struck seven fours in a quickfire knock before chopping on 19-year-old quick Esterhuysen (2 for 58).

New South Wales slumped from 203 for 3 to 225 for 6 largely thanks to Bryce Jackson's double-strike in the 30th over that sent Patterson and Edwards packing in the space of four balls. But Western Australia couldn't complete the job, with handy runs from Henriques, Abbott (35) and Charlie Stobo (39 in 20 balls) getting New South Wales well beyond 300.
