Western Australia 215 (Cartwright 78, Stobo 3-32, Copeland 3-42, Lyon 3-59) and 6 for 172 (S Marsh 39) beat New South Wales 204 (Hughes 49, M Marsh 4-50) and 179 (Cowan 55, Mackin 6-43, Kelly 4-25) by four wickets
Thirteen wickets fell on the third day at the WACA Ground where the hosts prevailed by chasing down 169 and grabbed 7.15 points against New South Wales. Western Australia's win was set up by the pace-bowling duo of Matthew Kelly and Simon Mackin who shared all 10 wickets between them. They bowled NSW out for 179 before Western Australia scored at nearly five an over to chase the total.
When NSW resumed on their overnight 3 for 77, Kelly struck on the second ball of the day and a little over six overs later again to reduce them to 5 for 89. Ed Cowan scored his 47th first-class fifty meanwhile, as Mackin ran through the tail to finish with 6 for 43 and Kelly ended with 4 for 25. It was Mackin's first five-for in first-class matches this season and Kelly continued his wicket-taking streak after taking eight in the BBL for the Perth Scorchers.
Trent Copeland retired hurt at 5 for 90 when he was struck while batting by Jhye Richardson and returned to bat later at 9 for 175. He later bowled 9.3 overs with an injured arm.
Western Australia lost their openers by the 11th over before Hilton Cartwright (32) and Shaun Marsh (39) rallied them towards 100. Gurinder Sandhu had both of them caught but only 33 runs were left when Marsh walked back and the hosts finished the chase in the 35th over.
NSW are still on the top of the table followed by Western Australia but both will be overtaken by Queensland if they take the remaining four Tasmania wickets on Sunday.
