Greg Norman would not have been your first prediction for British Open leader, two days in (he'll still be there, assuming K.J. Choi or Ian Poulter don't close out two under). However, you might have at least wagered on him at somewhere between 300 and 500:1, considering that he is a fairly popular name in the history of golf.

Darren Rovell points out that he if he actually holds on and wins this thing, he might go down as the most well backed huge underdog in the history of golf.

Many U.S. books, including those in Vegas, didn't even have Norman on the board. But the active shops in Europe had Norman as high as 300-to-1. It wasn't a bad read by the bookmakers. The guy hasn't played in a major since the British three years ago at St. Andrews. Those odds, for the most part, were slashed in half after Round 1, as the bookmakers don't believe Norman, who was wearing no logos aside from the familiar "Shark" logo on his hat, can keep up this pace.

Rovell picked up the tip from a few friends at sportsbooks and also points out that there have been bigger longshots, although most of them probably didn't carry a ton of money. (John Daly, Ben Curtis, Rich Beem, Todd Hamilton are all names that [don't] stand out in terms of having people bet on them before they won their first major.)

There's still plenty of weekend golf left, and there are still plenty of big, dangerous names lurking around the shark. Besides, he'd only dropped to 50:1 at BoDog before the second round, so if you don't believe, you're not the only one.
