SA break 13-year drought to claim one-day trophy

The Victorians were bowled out for 204 in 43.3 overs at Adelaide Oval as SA captured their first 50-over trophy since 2011/12.

"It has obviously been a long time," McSweeney said.

"The players that we have got in our stable now have shown over the last couple years that we can do it ... we're getting a little bit more consistent."

Victoria's run chase, with Marcus Harris flying on 41 from 42 balls, was well on track at 1-74 in the 14th over.

But McSweeney, who hadn't taken a wicket all tournament with his gentle offspin, then provided an unlikely - and decisive - turn.

Harris gave himself room to hit McSweeney through the offside, but smacked the ball straight to Jason Sangha at cover.

In his next over, McSweeney dismissed dangerman Peter Handscomb for one. The SA captain instinctively flung his right hand at a lofted straight drive, parried the ball, and completed a stunning catch on the second grab.

"I needed to get some overs in and I wanted to get them out of the way as soon as I could, so it worked out well," McSweeney said.

Within another eight overs, opener Campbell Kellaway (24 from 52 balls) and Sam Harper (12 from 13) were also out.

The Victorians had lost 4-30 in a sudden slide to 5-108 and were never in the hunt thereafter, despite captain Will Sutherland's 50 from 52 balls.

Sutherland lamented McSweeney's double delight in dismissing stalwarts Harris and Handscomb.

"It's always interesting when the part-timer comes on, whether you put your ego aside or not," Sutherland said.

"A few boys, particularly our senior players, were disappointed with their dismissal."

McSweeney finished with 2-14 from four overs, Nathan McAndrew took 3-47 and Henry Thornton cleaned up the tail to claim 4-27 and win the newly minted Michael Bevan Medal as player of the final.

In SA's innings, Nielsen top-scored with 68 from 93 balls, Lehmann made 67 from 75 and allrounder Scott, the player of the tournament, finished with a flourish with an unbeaten 54 from 37 deliveries.

Victoria's Sutherland (3-67) took three of the initial four wickets and veteran Peter Siddle claimed 3-40.

SA were wobbling at 4-118 in the 26th over, but Nielsen and Lehmann steadied with a 56-run partnership.

Lehmann then combined with Scott for a brisk 67-run stand, with the latter reaching his half-century from 36 balls in a flurry featuring seven fours and a six.
