But cometh the hour, cometh the man - step forward Scotland fly-half Dan Parks and take a bow - as the number ten scored six penalties and two drop goals to seal the win.
"The guys worked very hard and the front row was tremendous," said Robinson.
"We had to control the scoreboard in the second half. I was pretty frustrated first half, but I thought we had a good shape. Everybody worked together in a disciplined fashion.
"The outside backs worked well, we got the ball to the outside channels, the line-out was pleasing, although in one line-out we lost and they scored off it.
"I want to say that we've got to improve. There is still a long way for us to go, a lot of improvements. This is just a start.
"We are very pleased with the result, really pleased with the attitude of the whole squad, but next week's game is going to be very, very tough.
"We have the opportunity to get back-to-back wins in Argentina, which not many teams have done.
"We are pleased with the fact we are the first team to win in Tucuman on the back of the Ireland victory as well."
