When you're trying to win a tournament, you don't want to double-bogey two holes. Louis Oosthuizen learned that to his sorrow on Sunday, watching his 54-hole lead evaporate as Hunter Mahan swooped in for the win. Mahan becomes the first two-time winner on the PGA Tour this year, and heads into Augusta with all kinds of confidence. And heaven knows he could use it; after near-misses at the Ryder Cup and the Tour Championship, the guy has to break through sometime, right? Right?

It was the kind of putt most players would dream of having to win their first major championship: a simple one-footer to clinch a career-defining victory.

I.K. Kim found herself in that exact situation on Sunday afternoon at the Kraft Nabisco Championship. After going birdie-birdie on the previous two holes to take a one-shot lead going to the 18th hole, it seemed fitting that Kim's hard work would be repaid with a tap-in for the win.

Game over, drive home safely. Nobody misses a one-footer for the win ... except I.K. Kim. In one of the most incredible misses in golf history, Kim ended up watching the putt go in the hole and come back out, forcing her to settle for bogey and a playoff with Sun Young Yoo.

"We are told all the time, don't let it just be a formality," Golf Channel on-course announcer Judy Rankin said. "Go through your little routine and make sure you roll the ball in the center of the hole…You have to get yourself up for the playoff.  You can't let what happened on 18 affect how you play in the playoff.  And so often, it does."

Of course, the miss did affect Kim, who lost on the first playoff hole when Yoo rolled in a birdie putt for the win.

We tend to use superlatives in sports to describe a truly awful moment as the "worst" in a sport's history. More often than not that moment can be debated. This time around, however, there's no debating that was the worst miss in golf history. Period. End of story.

That's not to say he wasn't a decent pick, but even with his win earlier this year in the desert at the Accenture Match Play, there was still a host of big names you would have picked before him.

Guys with a major-championship pedigree and local Augusta National knowledge always top the list. But following his win on Sunday, the sweet-swinging Mahan appears to be peaking at just the right time, making him a legitimate pick to win not only his first major championship but also his first green jacket.

Mahan, who started the day two shots back of Louis Oosthuizen, wasn't spectacular during the final round, only carding a 1-under 71 on a day when conditions appeared to be absolutely perfect. But unlike a number of the guys near the top, Mahan stuck to his game plan and parred the field to death, stringing together eight straight to start his round before he birdied the ninth and 10th holes to move in front.

From there he kept the damage to a minimum to pick up his second win of the season, becoming the first multiple winner on the PGA Tour this year. Not only that, but also Mahan is now the top-ranked American in the Official World Golf Ranking with his victory.

Tiger Woods '13, on sale now.Devil Ball's Proving Ground is the space where we review the latest and hottest products in the golf world. Today, we kill time between rounds with the latest installment of the Tiger Woods video game series.

Quick hit: EA Sports' latest entry in the Tiger Woods franchise is a quirky, fidgety first step in a new world for video games.

Background: Gather 'round, young'uns, and I'll tell you of a time when video-game controllers had one stick and one button, and we liked it! Well, not really; we just didn't know any better. Most game controllers now have more buttons than your standard airplane cockpit, which is fine. But it's right about time for an advancement in controller technology, and Tiger Woods '13 jumps on board the Kinect bandwagon for XBox. (The game is also available for PlayStation 3's Move system.)

The entire golf world has its sights set on Augusta National with the first major of the year less than a week away, but a side story that has certainly been making the rounds this week is the release of Hank Haney's new book, The Big Miss.

Since the book was released on Tuesday, Woods' former swing coach has been making stops on the sports radio circuit, taking a couple minutes out to discuss the book and, hopefully, sell a couple extra copies. So when Haney joined WFAN's "Boomer and Carton" show on Friday to discuss The Big Miss (click here for the entire interview), many figured it would be a simple Q&A and nothing more.

But knowing co-host Craig Carton and what he's all about -- he's one of the most vocal, and opinionated, sports jocks in the business -- it was never going to be an easy interview. In fact, Haney got an earful from Carton for more than 20 minutes, as he and Boomer Esiason questioned the decision to publish a book about his time spent with Woods.

After taking shots from both hosts for the better part of the interview, Haney eventually hung up, but not before Carton called the instructor "a terrible human being" and "the scum of the earth."

Hey, what ever happened to Louis Oosthuizen? The guy we picked as one to win a few majors after his British Open triumph a couple years back really hasn't done a whole lot since then, but at the moment he's leading the Shell Houston Open along with Brian Davis. In the hunt: J.B. Holmes and Phil Mickelson, among others. Round 2 finishes up Saturday because of darkness; catch up with everything you need to know right here.

It honestly doesn't matter how poorly he's playing leading up to the first major of the year, all it takes is a whiff of the Azaleas or a couple practice days at August National -- Phil logged them prior to the start of the Shell Houston Open -- and boom! His game is on.

OK, so maybe it's not that easy. But like Jack Nicklaus, Arnold Palmer, Tiger Woods and Sam Snead, there's something about Augusta that brings out the best in Phil. And for some reason, those positive Masters vibes tend to rub off on the tournament he plays the week prior.

Case in point: Mickelson has four tour wins the week before the Masters, and one of those years (2006), he managed to go back-to-back to win his third Green Jacket.

Playing well the week before is always a positive sign, and once again, Phil is doing just that at the Shell Houston Open, posting 7-under 65 on Friday morning (he had to come back and finish his first round due) before coming back and firing a second-round 70 that has him sitting at 9-under, just three back of leader Jeff Maggert.

Prior to this week, nobody was quite sure which version of Phil Mickelson would show up at Augusta National, after he posted two pedestrian finishes during the Florida Swing that all but snuffed out the early season hype of winning at Pebble and nearly backing it up with another at Riviera.

But in typical Phil fashion, he's back on our golf radar right before his favorite tournament of the year. There's a reason why Fred Couples called Augusta National a "playground for Phil."
