"I just kept talking to him and looking for him to give me a response, just say anything."
The 136th Open ultimately ended with Pádraig Harrington celebrating a maiden major victory, but it is fair to say success did not come easy.
Harrington edged out Sergio García in a tense four-hole play-off in 2007 after the pair had finished regulation play on 7-under par. However, the extra holes were only required after the Irishman endured misery on Carnoustie's fiendishly challenging 18th.
When the Angus course had hosted The Open eight years earlier, Jean van de Velde famously finished with a triple-bogey 7 when a double bogey would have been enough to secure the Claret Jug, ultimately, giving Paul Lawrie the opportunity to triumph in a play-off.
On this occasion, Harrington held a slender one-shot lead as he reached the final hole. He and his caddie, Ronan Flood, were in no doubt as to the right approach.
