Western Australia secured a convincing 105-run victory over reigning champions South Australia at Adelaide Oval on Saturday, with Ashton Agar playing a key role by claiming three wickets on the final day of the Sheffield Shield clash.
Chasing a challenging target of 422, South Australia were bowled out for 316, handing Western Australia a crucial win and inflicting a second consecutive defeat on the defending champions.
South Australia resumed the final day's play at 182 for 1, with opener Mackenzie Harvey unbeaten on 90 and captain Nathan McSweeney on 57. The hosts appeared well positioned to mount a serious challenge for victory, but Western Australia's bowlers turned the game around with a series of crucial breakthroughs.
Harvey's impressive innings came to an end when Ashton Agar bowled him for 90, with the left-arm spinner finding a gap between bat and pad. McSweeney, who had looked in good touch, was dismissed for 66 after edging a delivery from Kieran Elliott to Cameron Bancroft at second slip.
McSweeney's dismissal proved particularly costly as the South Australian captain had been enjoying an excellent start to the season. He had scored a century for Australia A against India A earlier this month and followed it up with another hundred in one-day cricket for South Australia. He had also registered half-centuries in each of his previous two Sheffield Shield appearances.
Despite promising contributions from Harvey and McSweeney, South Australia suffered a dramatic collapse, losing their remaining nine wickets for just 132 runs.
Agar finished with impressive figures of 3 for 62, while Kieran Elliott, Jhye Richardson and Corey Rocchiccioli claimed two wickets each to complete Western Australia's victory.
Earlier, Western Australia posted 406 for 5 declared in their first innings before dismissing South Australia for just 154. The visitors then added 169 in their second innings, setting the hosts a daunting target of 422 runs. Cameron Bancroft and his teammates ultimately proved too strong for the defending champions.
The defeat marked South Australia's second consecutive Sheffield Shield loss in just 10 days, following their six-wicket defeat against Queensland, also at Adelaide Oval. Their title defence had begun positively with an innings victory over Victoria at Junction Oval.
South Australian coach Ryan Harris admitted that his team had let a promising opportunity slip away, particularly after beginning the final day in a strong position.
"We had it set up for a good day today," Harris said, while describing his team's batting performance as "not good enough".
Harris expressed disappointment with the batting unit, which had already struggled in the first innings and failed to capitalise on several promising starts in the second innings. Six of the top seven batters reached double figures but none managed to convert their starts into a match-defining contribution.
Western Australia's disciplined bowling performance ultimately proved decisive, as Agar and his teammates dismantled South Australia's batting order to seal an important 105-run victory and hand the defending champions another setback in their Sheffield Shield title defence.
