A magnificent century by Darren Lehmann led South Australia to a convincing win over New South Wales in the ING Cup cricket match here today.

Lehmann pressed his claims for a national one-day berth with 101 runs off just 95 balls to help hand his side a 114-run victory.

The Redbacks batted first after being sent in by NSW captain Stuart MacGill and were bowled out for 258 in the last over of the innings.

Test paceman Jason Gillespie then took 3-31 from 10 overs to help bowl the Blues out for just 144 with 5.1 overs to spare shortly before he responded to an emergency call-up to the Australian squad.

Gillespie was drafted after West Australian quick Brad Williams was ruled out with a broken thumb and Glenn McGrath received a one-match ban for dissent.

Lehmann came to the wicket with the Redbacks in trouble at 2-17 and wasn't dismissed until the score reached 199. He received good support from Ben Johnson (51 from 74 balls), and David Fitzgerald, who played solidly at the top of the order to make 33 from 70.

Allrounder Mike Smith chipped in with an unbeaten 30 from 18 balls, which included three sixes.

MacGill had the best figures for NSW, taking 5-53 from 6.5 overs after conceding 14 runs from his first over.

Stuart Clark and Nathan Bracken were impressive with the new ball taking 1-19 and 2-30 respectively.

When it was the Blues' turn to bat, they didn't take long to run into trouble, slumping to 7-73 with only left-hander Graeme Rummans holding the innings together with an unbeaten 73.

The NSW innings ended with Bracken edging paceman Mark Harrity through to wicketkeeper Graham Manou for nine.

Harrity, Johnson and Smith claimed two wickets each for the Redbacks while Paul Wilson took one.

Lehmann was delighted with the performance, saying it was the best so far this season for his side.

"We haven't batted, bowled and fielded better than that in the one day competition this season," he said.

"It was very pleasing and I just hope we can keep it going after the momentum we've built here".

MacGill was blunt in his assessment of the Blues' effort.

"It was embarrassing, really, we have no excuse for that performance," he said.

"The difference between the sides was the big partnership between Darren (Lehmann) and Ben Johnson that set up the South Australian innings.

"As far as our batting goes it was simply not good enough.

"There was nothing wrong with the wicket, in fact we'd like to play all our matches on a wicket as good as that one."
