Rory McIlroy lost all three of his group games in Antalya, including by six shots to Tiger Woods this morning [Thursday], but was more than happy to spend the afternoon on the beach with girlfriend Caroline Wozniacki instead of contesting the semi-finals.
Those came down to clashes between Woods and Rose and Westwood and Charl Schwartzel, with Westwood following this morning [Thursday] 64 against Hunter Mahan with a stunning 61 - which included a double bogey - to beat the former Masters champion Schwartzel by six shots.
And Rose then turned around his match with Woods in spectacular fashion, recovering from two behind after 12 with a birdie on the 13th and an eagle on the 14th, where his approach pitched just inches from the hole and span back into the cup.
Both players then birdied the par-five 16th and when Woods missed from 15ft for birdie on the last to force sudden death, Rose was certain of a seven-figure payday.
First prize tomorrow [Friday] is USD 1.5million (£935,000) with 1million (£623,000) to the runner-up, while Schwartzel and Woods collected USD600,000 (£374,000) as losing semi-finalists.
Westwood holed from 15ft for an eagle on the third, but double-bogeyed the next after hitting a flyer over the green which finished up against a tree.
However, he then holed a bunker shot for a birdie on the sixth and drove the green on the short par-four ninth to set up another eagle, while he also chipped in for another birdie on the 13th for good measure.
"It was just one of those days where I got on a roll and the hole started to look bigger and that's not happened for a while," said Westwood, who has been working hard on his short game with former European Tour professional Tony Johnstone.
"It was pretty special stuff.
"I'm just pleased to be playing well and getting back in the swing of things after the Ryder Cup, with no hangover from that."

Asked about being guaranteed USD 1million in the final, Westwood added: "I hadn't really thought about that.
"It's nice obviously. I have been successful in golf and done very well, and I am in the fortunate position now of going to tournaments with the sole purpose of trying to win.
"I know what a luxury I have to play this game and play it for fortunes - it's not often you see me miserable is it? I try and play with a smile because I know how lucky I am."
Rose also had reason to smile after carding a 62 in the morning to beat US Open champion Webb Simpson and following it with victory over Woods.
"It was a great day," said Rose, who was stunned to learn Westwood had shot 61 in the trickier afternoon conditions. "It was an ugly match until the end.
"It was hard to come out and get a rhythm going this afternoon for the both of us. It felt like the Ryder Cup to be honest, the transition between morning and afternoon felt difficult there and today [Thursday].
"There's also a lot more noise and kerfuffle when playing with Tiger, but I hung in there and tried to draw upon the fast finishes I've had of late - he birdied the last two holes to beat Phil Mickelson at Medinah - and got a stroke of luck on 14.
"I just had to look up and give Tiger a wry smile, there's not much you can do about that."
Woods added: "That was a big switch right there. All of a sudden I was one down with four to go.
"It's a neat format because it's never over until the end, but it's frustrating that I lost two matches by one shot and just did not play well enough to win those matches."
Earlier in the day, McIlroy could console himself with the thought that his USD 300,000 worked out at USD1,382 per shot, with the Ulsterman taking six more in total than seventh-placed Mahan, who also lost all three games.
"I've got an afternoon by the pool, I don't mind," McIlroy said. "I knew I was going to have an afternoon off anyway so I was just going out and playing. I never really had any expectations.
"I've treated this week as it's great to come here, nice weather, play a bit of golf, I get to spend some time with Caroline (Wozniacki) - I viewed it as a week like that. I didn't touch a club until the first day."
McIlroy will have next week off and hopes to join Wozniacki at her tournament in Moscow if he can get a visa, before concentrating on protecting his lead at the top of the European money list.
"I have still got some big events left and I would love to win the Race to Dubai so I am going to give it one last push," added McIlroy, who could match the achievements of Luke Donald last year and top the money list on both sides of the Atlantic.
"It has been a great season and I am ready to be done. It is just such a long season these days but I feel I have got an obligation to play some big events leading up to Dubai."
