Not content with making the blunder that cost the Sharks the Super 14 title last weekend in Durban, Walsh was at it again yesterday in the Bloemfontein crisp winter sunshine. His was a simply awful performance.
South Africa's superiority was extensive enough without Walsh making mistakes that handed them scores on a plate. But that was how the Springboks scored their first try of a palpably one-sided game and it set them on the way to an easy, runaway win that represented a completely hollow victory.
Wynand Olivier clearly took out two defenders when the ball was moved right in the 23rd minute. But the obvious crossing never occurred to blunderbus Walsh and recalled wing Ashwin Willemse was able to stroll over in the right corner for the first of his team's hatful of tries.
If referees cannot see such clear incidents as that they shouldn't be handling schoolboy games, never mind international matches.
By then, had not Walsh already shown where his sympathies lay?
South Africa were able to make 25 metres downfield after he warned England he was playing advantage for offside. He had oceans of time to call 'advantage over', yet when Bryan Habana was forced into touch he took play back for the penalty from which Percy Montgomery kicked his second three-pointer.
Moments later, Walsh called advantage for numbers in the line-out. Yet when England made a maximum of one and a half metres, Walsh called 'advantage over'.
Just to add to Walsh's long list of failures, he totally failed to get on top of the mess at the set scrums. Sometimes, you despair at the standards of international refereeing - and this was one of those days.
But England coach Brian Ashton had said there would be no excuses whatever happened and not even Walsh's inadequacies could mask England's crushing failure to compete properly at this level.
