Who is the sentimental favorite at the U.S. Open?

There are a number of compelling storylines in the U.S. Open -- besides the rain and constant delays that pushed the final round back to Monday.

Currently tied for the lead at 7 under par is virtual unknown Ricky Barnes. Barnes has never won an event on the PGA Tour. Or come in the top-three. Or top-ten. The 28 year old has made just 6 of 12 cuts this year -- but he has a very good chance of winning a major. Yes, the 519th ranked guy in the world might be the U.S. Open champion at this time tomorrow.

Barnes is tied with Lucas Glover, a guy who has won exactly one event on the PGA Tour. ESPN golf writer Jason Sobel tells us how that victory happened back in 2005:

In fact, his only career PGA Tour victory came four years ago, when on his last two holes he drained a 50-foot birdie putt from the fringe and knocked in a 40-foot bunker shot. If he can replicate that feat on Monday, he'll be a hero, but those dramatics are a once-in-a-lifetime occurrence.

Five strokes back, at 2 under par and tied for third, there are more compelling stories.

Phil Mickelson's wife was recently diagnosed with breast cancer. Mickelson left the tour to be with his wife. Mickelson's wife had been to the previous 61 major events (that's fifteen years worth and change), but she is missing this U.S. Open.

Tied with Mickelson and two others is David Duval. Duval was once one of the top golfers in the world, with 13 PGA Tour wins to his credit, including the 2001 U.S. Open. But now, he is ranked 882nd in the world, and hasn't won an event since that U.S. Open eight years ago.

Oh, and another two strokes back, at even par, is that guy named Tiger Woods. Of course, he's seven shots back from the leaders, and has already played seven holes, so it would take an epic collapse and an epic final eleven holes for Tiger Woods to win.

So, knowing all of this, who are you cheering for?
