SA beat Vics to win first one-day trophy in 13 years

Nathan McSweeney's game-changing cameo with the ball has helped South Australia defeat Victoria by 64 runs to collect the state's first one-day cricket title in 13 years.

SA, with Harry Nielsen, Jake Lehmann and Liam Scott making half-centuries, posted 7-268 in Saturday's battle for the inaugural Dean Jones Trophy.

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

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.

Five overs later, Victorian opener Campbell Kellaway (24 from 52 balls) top-edged a pull shot from the bowling of Brendan Doggett (1-41) and was caught by wicketkeeper Nielsen.

Soon after, Sam Harper (12 from 13) was caught by Nielsen when attempting a leg glance from Nathan McAndrew.

The Victorians had lost 4-30 in a sudden slide to 5-108 in the 24th over and were never in the hunt thereafter, despite captain Will Sutherland's 50 from 52 balls and Tom Rogers' 26 from 51.

McSweeney finished with figures of 2-14 from four overs, McAndrew took 3-47 from eight overs and Henry Thornton cleaned up the tail to claim 4-27 from 9.3 overs.

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.

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

SA made a solid start with openers Nielsen and Mackenzie Harvey putting on 44 runs before Sutherland struck in the eighth over.

Harvey, who hit two fours and a six in his 23 from 23 balls, chopped on to his stumps when attempting to force through the off-side.

Sutherland claimed Daniel Drew (13 from 21 balls) in the 14th over and McSweeney (seven from 15) soon followed.

And when Sangha (15 from 26) fell to Sutherland, SA were wobbling 4-118 in the 26th over, before Nielsen and Lehmann steadied with a 56-run partnership.

Lehmann later 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.
