The Tasmanian Tigers have broken through for their first win of the JLT One-Day Cup tournament, crushing South Australia by 129 runs at North Sydney Oval.

After losing the toss and being sent in, the Tigers lost Ben McDermott early in their inning when he was trapped LBW for a duck.

That brought Ben Dunk (45) and Alex Doolan (62) to the crease, the pair putting on 77 for the second wicket.

Doolan then combined with captain George Bailey for a 49-run stand before he was adjudged LBW to Michael Cormack.

Bailey and Matthew Wade then set about smashing the South Australian attack to all parts, putting on 125 runs in just 81 balls for the fourth wicket.

Bailey was eventually dismissed for an impressive 86 from just 62 balls chasing further quick runs in the dying stages of the inning.

Wade departed soon after for 46, which left James Faulkner to finish the job. Finish the job he did, belting 34 not out from just 19 deliveries.

The Tigers producing their best batting performance of the tournament so far, finishing at 6-315.

South Australia got off to a flying start in reply, making their way to 0-42 from the first seven overs.

But debutant Nick Buchanan made the breakthrough with his very first ball, claiming the wicket of Jake Weatherald for ten.

Alex Carey and Callum Ferguson pushed the score along to 1-84, before Tom Rogers claimed Carey for his first wicket.

Youngster Riley Meredith then took the big wickets of Tom Cooper and Alex Ross, before Ben Dunk produced some magic with the ball to dismiss Ferguson and Jake Lehmann.

That left the Redbacks floundering at 6-128, with Cameron Boyce cleaning up the tail to close the South Australian inning at 186.

Dunk (3-14) and Boyce (3-27) were the chief destroyers, with Meredith (2-31), Rogers (1-35) and Buchanan (1-43) all claiming wickets.

The Tigers will look to add a second win to their JLT Cup campaign, when they take on the CA XI at Hurstville on Friday.
