Scorecard

Super-sub Malinga Bandara captured four quick wickets to help Sri Lanka [Images] to a 76-run victory over South Africa at Bellerive Oval in Hobart on Tuesday.

Sri Lanka will now meet Australia in the triangular one-day series finals.

"It's nice to get a win under out belt," Sri Lanka coach Tom Moody said in a televised interview.

"Today was a lot better performance all round really."

Bandara destroyed the South African batting lineup, taking 4-31 from nine overs with his leg-spinners, as the Proteas collapsed to be all out for just 181 in reply to Sri Lanka's 257-9.

South Africa had needed to win just one of their last three matches to reach the finals but back-to-back losses against Australia meant everything was at stake in Tuesday's last preliminary match.

Sri Lanka made a flying start after winning the toss and electing to bat first, Marvan Atapattu and Kumar Sangakkara both scoring half-centuries.

Atapattu slammed 80 off 122 balls then Sangakkara smashed 62 from 77 deliveries as the Sri Lankans raced to 175-1 in the 36th over when the South Africans suddenly hit back.

Paceman Johan van der Wath broke a 123-run stand between Atapattu and wicketkeeper Sangakkara when he had the latter caught by Boeta Dippenaar at mid off.

MINI-COLLAPSE

Van der Wath dismissed Atapattu in his next over, caught by Andrew Hall [Images], which triggered a mini-collapse.

Sri Lanka lost a steady stream of wickets to slump to 229-7 in the 47th over before Tillekeratne Dilshan chipped in with a rapid 30 to push the total past 250.

Hall was the pick of the South African bowlers, completing his 10 overs with figures of 3-50, while van der Wath and Charl Langeveldt grabbed to wickets each.

South Africa's reply started badly when they lost Dippenaar (nine) and Herschelle Gibbs [Images] (no score) to Chaminda Vaas [Images], slumping to 19-2.

South African skipper Graeme Smith [Images] finally found form, completing his first haf-century of the tour, but after he fell for 67 the rest of the batting order collapsed.

Bandara, who came on for Atapattu, had Smith caught by Muttiah Muralitharan then trapped Justin Kemp in front for a golden duck.

He took a sharp return catch to remove Ashwell Prince for 22 then had Shaun Pollock [Images] caught behind for 15.

The first final between Australia and Sri Lanka will take place in Adelaide on Friday with the second match scheduled for Sydney on Sunday. A third match, if required, will be held in Brisbane next Tuesday.
