Kallis took five for 30 as West Indies plunged from 180-3 to 245 all out in 49.3 of their 50 overs.

South Africa surged to a four-wicket victory at 248-6 with three overs to spare.

Wallace: Hit 103

Their triumph in the one-day competition came less than two months after their victory at the Commonwealth Games in Kuala Lumpur.

The West Indies rarely played to their potential. The batting collapse in which their last seven wickets went for 65 was followed by undistinguished fielding.

Kallis was judged man-of-the-match for his five-wicket haul and a useful 37 runs. His excellent form in the tournament included a century and three wickets against Sri Lanka in the semi-final.

His pace bowling restricted the West Indian scoring after a maiden one-day international century by opener Philo Wallace had set up the Caribbean team for a big score after they were put in when Cronje won the toss.

Kallis defiant

Kallis ripped the heart out the West Indian middle order and tail.

In a spell of 7.3 overs, he removed Carl Hooper (49) and Phil Simmons (8), both caught by Jonty Rhodes, and tail-enders Ridley Jacobs (14), Rawl Lewis (0) and Reon King (7), all leg before.

Kallis also had a chance for a hat-trick, after he removed Hooper and Lewis in consecutive balls in the 46th over.

The West Indies took 25 overs to reach 100, spinners Pat Symcox and Nicky Boje doing an effective containing job, but Wallace subsequently lifted the tempo.

Once Wallace reached his half century off 72 balls, he ripped into the South African attack, adding his second 50 in just 26 balls, and bringing up his century with two consecutive fours off pace bowler Steve Elworthy.

Wallace's innings of 103 off 102 balls included five sixes and 11 fours, and was ended when he was stumped off Cronje's gentle medium pace by wicketkeeper Mark Boucher.

Hooper apart, the other West Indian batsmen, including captain Brian Lara (11), threw away their wickets cheaply in the pursuit of quick runs.

South Africa were always above the run rate required after openers Mike Rindel (49) and Daryll Cullinan (21) blasted 50 off the first six overs.
