There's one image that's stuck with me from the tragedy at the Boston Marathon finish line. It's in the video of the finish, when the runners are nearing the line at the 4:09 mark. The explosion goes off, and one runner just collapses and begins rolling on the ground. Was he hit by shrapnel? Knocked down by a shock wave? I don't know, but I hope he's one of the fortunate ones.

It hurt, seeing that guy fall within literally feet of the finish line, because he was on the cusp of one of the greatest moments of his life. He was right there. This is something like what he was feeling, what it feels like to finish a marathon:

• Your body isn't your own anymore. Ever had that feeling when you touch hot water, and just for an instant, it feels cold? That's how your legs feel. Your feet? Forget it. They're bricks.

Runners continue to run towards the finish line as an explosion erupts. (Reuters)• Your arms, which have been pumping for the last two, (if you're world-class) three, (if you're very good) or four (if you're my speed) hours, feel like you've been

Adam Scott reacts after making a birdie putt to win the Masters. (Getty Images)AUGUSTA, Ga. – Adam Scott wasn't just in a swoon. He was in an absolute free-fall.

It was September 2009, and Scott was in the midst of the worst stretch of his professional career. He'd seen his world ranking drop from 3rd after the 2008 U.S. Open to 53rd. He'd missed cuts in 10 of his last 14 events and in four of the pri five majors. He'd broken up with a longtime girlfriend and had made some dubious business decisions, like the purchase of a Gulfstream G450 jet.

Fellow Australian Greg Norman knew all this and still selected Scott for the 2009 Presidents Cup team.

Norman came under withering criticism for picking the underachieving Scott, criticism which served to motivate Scott that much more.

"It was kind of a gut-check time," Scott said on Sunday evening. "My game was in a bit of a rut, to be fair, and I wasn't enjoying it. But Greg as the captain had a lot of faith in me, and belief that I could

AUGUSTA, Ga. – The gray, rainy afternoon was one of the ugliest in years at Augusta, but for Adam Scott, it’s one of the most beautiful of his life.

With the rain steadily falling,  Scott and Angel Cabrera back-to-backed two of the finest pressure shots in recent memory at Augusta. Scott stood on the 18th green, his ball 30 feet from the hole, his telephone-pole-sized belly putter in his hand. Behind him, Cabrera stood in the middle of the fairway, waiting. The two were tied at 8-under after 71 holes. Only one remained.

Scott found the putting stroke that had eluded him during the final holes of his British Open collapse last season, draining a putt that toured all the way around the cup before dropping in. But before Scott could even reach the white bricks of the scorer’s building, Cabrera’s approach dropped to within four feet of the cup. One birdie later, and the Masters was headed to extra frames.

On the first playoff hole, No. 18, the players matched each other virtually stroke for

AUGUSTA, Ga. - In a Masters that just keeps getting stranger, it's a former Olympic skier, of all things, who's now your clubhouse leader in the battle for weirdest moment of the weekend.

On Saturday, news broke that a television viewer had called in a violation on Tiger Woods for play on Friday; a subsequent investigation penalized Woods two strokes. And then, late Saturday evening, the following tweet showed up.

No problem Masters tournament happy to call in and help. You always have to keep an eye on those cheaters ;)yhoo.it/Zh7TBu

That there is Thomas Vonn, former Olympic skier and ex-husband of Lindsey Vonn. You know, the Lindsey Vonn who's now Tiger's girlfriend. The same Tiger who, as you may have heard, admitted to cheating on his wife of many years.

Yeah. This is, well ... kind of awkward. But still funny. Nice job of making us both laugh and cringe, sir. (Oh, and thanks for the link, too.)

Now all we need is a comment from Tiger's

Bubba Watson joins the Green Jacket crew. (Getty Images)

AUGUSTA, Ga. – Late Sunday afternoon, on the putting green just past Augusta’s 18th green, Bubba Watson will perpetuate one of the great traditions in sports when he slips Augusta National’s fabled green jacket onto the shoulders of the 2013 Masters winner. It’s a fine piece of clothing, this green jacket, and you can’t have one any more than you can have a Super Bowl ring or the Stanley Cup trophy. But where did the jacket come from? What are its legends? And is there a way you actually could get your hands on one? Read on:

Where did the green jacket come from?
The single-breasted, brass-buttoned jacket dates to 1937, when Augusta National purchased the jackets in bulk from the Brooks Uniform Company in New York City. The idea was to give club members an easily-identifiable visual style during the tournament.

How are current jackets made?
Hamilton Tailoring Co. has made the jackets for the last 40 years. Each jacket takes about a month to produce and uses about 2 ½ yards of cloth.

AUGUSTA, Ga. - For a brief moment, Tianlang Guan was Augusta's cause célèbre, a 14-year-old amateur who'd captured the sympathy of the golf world when Augusta National tagged him with a controversial slow-play penalty. But he made the cut on the number, and for a brief moment, all was forgiven.

Then came the Tiger Woods possible-DQ scandal, and Guan suddenly became yesterday's news, literally and figuratively. The slow-play penalty was a sidelight to the possible disqualification of the world's No. 1 golfer, and Guan was left to do what he came here to do: play golf.

And he did, better than you or I ever could at Augusta but not well enough to make much of a dent in the leaderboard. He carded five bogeys and finished the day with a 77, leaving him at +9 for the tournament and right at the bottom of the field that made the cut. The highlight, though, was a long — Guan estimated it at 20 yards — putt on 18 to save par.

Still, when he finished, he was parked between a couple notable

Tiger Woods — Getty ImagesTiger Woods has been served with a two-shot penalty for a violation that occurred on Friday's 15th hole. He will tee off at 1:45 p.m. Saturday and is now five strokes behind leader Jason Day.

Woods faced disqualification stemming from a possible rules violation committed on Friday afternoon. After he struck one of the unluckiest shots in his Masters career, an approach on 15 that hit the flagstick and bounced back into the water, Woods dropped a new ball and began playing again. However, it's how he dropped that new ball that's at issue.

[Masters 2013 leaderboard: See how Tiger Woods and others are doing]

The rules of golf stipulate that a player may drop a ball in a designated drop zone, drop in the original spot from which the ball was hit, or drop in a spot that's in a direct line from the flag to the place where the ball last hit the water. Woods appeared to combine options 2 and 3. (For a fuller explanation of the rules at issue, see here.)

However, there was enough wiggle room in

AUGUSTA, Ga. - At this writing, patrons are streaming into the gates of Augusta National in advance of Saturday's third round of the Masters. They've paid hundreds, even thousands of dollars for their badges today, and since they've left their cell phones in their cars, they're blissfully unaware of the fact that Tiger Woods faces the very real threat of disqualification for a rules violation.

But you're not unaware. I'm not unaware. Woods isn't unaware. And Augusta National most certainly isn't unaware.

[UPDATE: Woods has not been disqualified. He has been served with a two-shot penalty but will play on.]

Put simply, Woods appeared to take an improper drop following a shot on 15 Friday which found the water. (See here for a clearer explanation.) There's gray area - about the only gray you'll find anywhere near Augusta National - but there's enough blood in the water to suggest the appearance of impropriety.

And since, for Augusta National and the game of golf in general, appearance
