PORT OF SPAIN, Trinidad, March 21 (AFP) - South Africa beat the West Indies by 69 runs in the second Test at Queens Park Oval Wednesday in what South African captain Shaun Pollock described as "the most intense Test match I have played in."

Pollock said his team had won because "we stuck to our disciplines and our game plan." Starting the last day needing another 200 runs to win with nine wickets standing, the West Indies quickly lost four wickets for 19 runs to crash to 51 for five.

Such a good start to the day was a bonus, admitted Pollock, but he said his players showed their worth during a 92-run stand between Ramnaresh Sarwan and West Indian captain Carl Hooper.

"It was a waiting game and a patience game," said Pollock. "We discussed the fact that every now and then partnerships would develop and that when it happened we had to hang in. We knew that when a break came we could go through."

So effectively did South Africa hang in that Sarwan and Hooper could add only 57 runs during the afternoon session before Sarwan succumbed to the pressure and was caught at square leg trying to hook.

That started another collapse in which the last five wickets fell for 19 runs.

Pollock said the slow pitch and slow scoring rate added to the intensity of a match in which he said fortunes shifted throughout.

West Indian captain Carl Hooper said he was disappointed with the collapse Wednesday morning. "We had four days of good cricket and then fell away today," he said.

Hooper said more application was needed by the batsmen. "We need to turn 40s into hundreds," he said. But Hooper said he was heartened that the West Indies had shown they were competitive during the first two Tests of a five-match series. The first match in Georgetown, Guyana, was drawn.

Sarwan fell to a spectacular catch shortly before tea. Just when it seemed his stand with Hooper had swung the game back to the West Indies, Sarwan hooked Jacques Kallis and Nicky Boje, fielding about 45m from the bat, turned and leaped to hold a fine catch.

Ridley Jacobs, who made 93 not out in the first innings, was the last major batsman and he started aggressively before being run out.

Called for a leg bye by Hooper, Jacobs was beaten by the speed and accurate throw of Herschelle Gibbs who raced in from backward point to pick up the ball near the batsmans wicket and throw down the stumps at the bowlers end.

Hooper finished with 54 not out after batting for 230 minutes. He faced 172 balls and hit five fours. Kallis finished with four for 40.

Allan Donald took the first two wickets of the morning after the West Indies resumed at 32 for one.

South African captain Shaun Pollock had Chris Gayle caught behind and Makhaya Ntini claimed the prize wicket of Brian Lara with his first delivery of the innings.

The West Indies slide started in the fourth over of the day when nightwatchman Dinanath Ramnarine edged a hard catch to Kallis at second slip off Donald without adding to the 11 runs he scored Tuesday.

Marlon Samuels hit two impressive boundaries but had made only nine when he went on the back foot to Donald and edged another catch to Kallis at second slip.

With several deliveries keeping low, going back was becoming increasingly hazardous but Gayle, after making a solid 23, went back to Pollock and edged a low catch to wicketkeeper Mark Boucher.

Donald was rested after a spell of 7-3-8-2 and his replacement, Ntini, struck a crucial blow with his first delivery, dismissing star batsman Lara for the third time in successive innings.

Lara went back on his stumps and was struck low on the pad. West Indian umpire Billy Doctrove gave him out but replays showed the ball had pitched well outside leg stump.
