There are three basic ways of winning a golf tournament - and Justin Rose has now joined an incredibly exclusive band of players to have done all three.
Type 1. Blitz the field
The first is by far the simplest, but also perhaps the toughest: all the average tour pro has to do on any given week is play to their absolute potential, and they will walk away with any golf tournament in the world simply because the margins for error in the sport are such that it's almost unheard of for more than one player at a time to really click into gear.
Such is the level of skill enjoyed by the world's greatest players that when everything clicks, they will hit every fairway, pepper every pin and roll in every putt. Both inspiring in its brilliance and slightly depressing in its unobtainability, the type 1 victory is a golfing marvel - and you always know it when you've seen it.
Poster boy: David Duval, who shot an extraordinary final round of 13-under-par 59 to win the Bob Hope Chrysler Classic in 1999 at the PGA West Stadium Course in La Quinta, California.
When Justin did it: The 2002 British Masters at Woburn. A relatively slow start on Thursday and Friday with a 70 and a 69 was followed by back-to-back rounds of 65 at the weekend meant nobody else in the field had any chance.
2. Ride the wave
The second way of winning is by far the most common: almost all golf tournaments are won this way, simply because - as noted above - the margins for error in golf make it common for a tournament to go by without one player managing to outplay the others.
It's a victory that sees players maximise their own solid play, holing the critical putts, making the sand saves, having their balls just clear the ponds and sighing in relief as the wayward drives leave routes through the trees.
Hand in hand with the player's own performance goes the slight miscues by opponents, whether through mental aberration or misfortune. But the heart of it is that the ultimate winner happens to enjoy enough of an up just as his opponents were on a bit of a dip. Any time you feel a different player could have won if the event had gone on for another two or three holes holes, you know you've just seen someone riding the wave.
Poster boy: Nick Faldo, whose dozens of career victories almost always relied on the failings of others rather than his own solid play. His three Masters titles were handed to him by the failings of Scott Hoch, Ray Floyd and Greg Norman, for example, and of all his Major victories only at the 1990 Open at St Andrews did he leave the field in his wake.
When Justin did it: There could be no better example than his victory at the Memorial Tournament a few weeks ago, when Rickie Fowler's two bogeys and a double bogey on the back nine helped the neat-and-tidy Rose inherit a straightforward win.
3. Too good to lose
A few years ago a statistician spent several months poring over average scores on the US Tour, and made two conclusions. The first wasn't that interesting: when golf pros win tournaments, they are playing better golf than they normally do. The second conclusion, however, was outrageous: there is a select band of players whose level has, at times, become good enough that they can win without even matching their 'normal' level of play.
At the time of the survey, in 2006, this group of players consisted solely of Tiger Woods. In the past, it has at various times included the likes of Faldo circa 1992 (when he carried all before him in Europe), Jack Nicklaus circa 1972 (when he was within a Lee Trevino chip-in of winning four Majors in a row), and Vijay Singh circa 2004 (when the Fijian won 14 tournaments in the space of 18 months).
Reaching this level is quite incredible: it means that a player has become so good that they can contend with their eyes closed; that they can appear to hack around the course and still end up tied for third or fourth; and that they can pick up trophies merely because nobody else is having even a reasonably decent week.
Like great poker players with the knack of folding losing hands and piling in on winners, these golfers fill their boots with birdies when the going is good, yet have the grit to stick in and minimise the damage when things go wrong. It's a rare talent, and one that makes 'Too Good To Lose' victories the rarest in the sport, because they show a golfer blessed - at least temporarily - with the nearest thing to golfing infallibility.
Poster boy: Tiger Woods, whose astonishing six victories in a row in 2006 is perhaps the greatest of all his achievements - even if Byron Nelson's 11 wins in a row back in the 1940s was at least as good.
When Justin did it: Justin Rose isn't just a golfer on a roll; he's a golfing juggernaut rolling down a hill with no brakes just at the moment. And with his win on Sunday, Rose pulled off the ultimate: he won despite not being at his best.
It isn't just that Rose has won two of his last three events that makes Bunker Mentality say this; it's the fact that he blew a healthy lead going into the final round of the other tournament.
That showed that he's not playing his best. He showed it again during Saturday's third round of the AT&T National, when he was all over the place on the back nine.
Yet rather than drop out of contention, as he once might have done, he scrambled like Seve, putted like Tiger and ground like Faldo to end up with a 67 that kept him in pole position. An eagle at the ninth on Sunday put him five shots clear; and even after he was subsequently almost caught, he was Tiger-like in his ability to casually par his way home to finish things off.
Could Rose go on to win The Open at St Andrews? Possibly - but in all honesty it seems unlikely, simply because he is not playing well enough, and if someone else has a great week then he will not. Yet the fact that his golf has reached the astonishing level at which it now sits suggests that you'd bet against him at your peril.
Quote of the week: "A lot has changed in the a few weeks. In the past I've worried about all sorts of questions: I've worried about where I fit in, how I stack up, what people think, where do they rate me, do they or don't they, and I've got to tell you I'm less worried about that now. That's not what's driving me. How good can I get at this game? That's a personal challenge and a personal quest. That's really all I'm focused on and I'm not really worried about where I stack up to others." - a positively Zen-like Justin Rose on his success.
Shot of the week: Rose's superb wood approach to set up the eagle that put him five shots clear -or-less guaranteed victory was the best fairway wood shot BM has seen under pressure since Padraig Harrington's at the 71st hole of The Open at Royal Birkdale in 2008.
