The dismissal of Kallis prompted the collapse

Jacques Kallis, who had made a composed 51, lost his head and then South Africa collapsed.

Kallis tried to swing Dinanath Ramnarine through mid-wicket off the second ball after lunch but only succeeded in dragging the ball onto his off stump.

Two balls later the leg-spinner set West Indies on their way to victory when Mark Boucher edged him to wicket-keeper Ridley Jacobs.

From being in with a slim chance of winning the match, South Africa had slumped to 209 for six and could only try to save the match.

With the stage set, Walsh took the new ball and not for the first time in his career produced the goods.

He removed Justin Kemp lbw off the first ball he faced and then almost had two wickets in two balls when Allan Donald was dropped first ball.

McKenzie was the only wicket to fall in the morning

Mervyn Dillon removed South African captain Shaun Pollock to set the scene for Walsh to retire a winner.

The 38-year-old veteran did not have long to wait to get Donald when he produced a classic yorker to send the fast bowler's middle stump cartwheeling through the air.

Everyone in the packed Sabina Park ground was urging Walsh to claim the final wicket but Dillon ripped up the script to snare Paul Adams.

The tailender hoisted the ball to point where Marlon Samuels pouched the catch to win the match.

Despite the winning end, Walsh and West Indies lost the series 2-1.

Earlier in the day it appeared South Africa could produce an unlikely victory.

Neil McKenzie and Jacques Kallis put on 66 for the fourth wicket, before the drama began to unfold.

McKenzie reached a composed half-century, but eventually fell to the bowler who had caused him the most trouble, Ramnarine.

Hard work

The South African had been unable to read Ramnarine's variations throughout his innings and the leg-spinner prompted the right-hander to push the ball to Leon Garrick at silly mid-on when on 55.

The Test debutant held a sharp chance low down to haul West Indies back into contention as the game threatened to escape their grasp.

But Walsh, Dillon and Ramnarine struck after lunch to seal the win and give Walsh the send off he so richly deserved.
