Rose shot a 69 which included two birdies and an eagle in the last six holes to beat the world no2 and admitted afterwards that any victory over Westwood is one that he would “dearly love”.
“That shot at 14 was easily the turning point,” said Rose. “In proper matchplay you would only win the hole but in this format I’ve picked up two shots on Tiger and it’s helped me win the match.
“It’s now an all-English final with Lee. I would dearly love to win as I want to stay fresh and hungry for the rest of the season.
“There is very little history of Westwood and me playing each other but being the world no5 at the moment it would be great to get one over the world no4.”
Westwood, who secured a six-stroke win over Charl Schwartzel in the tournament’s other semi-final, said of his round: “It was just one of those days when I was on a roll”.
