Aussies dismiss Sri Lanka cheaply
Australia dispatched Sri Lanka for just 101 on a bowler-friendly Cape Town surface to be in prime position to make the ICC World Twenty20 semi-finals.
Stuart Clark excelled with 4-20 after wickets had fallen in the first three overs of an effective quarter-final.
Sri Lanka would have been 11-4 if Brad Hodge had caught Kumar Sangakkara on six, the batsman finally out for 22.
Clark struck consistently, however, the only downside for Australia being another injury for Shane Watson.
The Queensland all-rounder, in for Ricky Ponting (hamstring), was making his first appearance of the tournament.
But he has been dogged by injuries in his international career.
And after Lasith Malinga hoicked the second ball of his final over beyond the rope for Sri Lanka's only six, Watson limped out of the fray.
The over, the 19th of the innings, was completed by Andrew Symonds, who promptly had Chaminda Vaas (21) caught at deep mid-wicket.
And the last wicket fell in the final over - Dilhara Fernando becoming a second victim for Nathan Bracken when he gave the bowler a simple return catch.
Left-arm seamer Bracken had celebrated his first wicket either side of Lee's initial incisions into Sri Lanka's top order.
With Adam Gilchrist winning an important toss - batting at 10am in Cape Town in springtime is not a friendly prospect - the Aussie bowlers were on the money throughout.
Lee did win a fortunate lbw decision to get the ball rolling with the wicket of Sanath Jayasuriya.
But most other Sri Lankans found scoring opportunities severely limited with the swing on offer and the ball not quite coming onto the bat.
They generally got out to rash shots, with three catches offered to third man and two to backward point - including a brilliant one-handed take by Michael Clarke.
The highest individual scorer was Jehan Mubarak, with 28.
