Jordan Spieth fired an 8-under 64 in the first round of the Masters to take a three shot lead into Friday, and that has him as the heavy favorite to win in updated betting odds.
Here's a look at some of the current odds to win the Masters after the first round (according to Bovada):
Favorites:
Jordan Spieth (now 2-1; was 8-1)
Jason Day (now 5-1; was 14-1)
Rory McIlroy (now 10-1; was 11-2)
Justin Rose (now 11-1; was 33-1)
Spieth is the clear favorite, and if you are content trying to just double your money it's still not terrible to grab him at 2-1 with a three shot advantage. Day showed the ability to get hot today with five straight birdies on the back, so 5-1 isn't bad value there.
I'd only take Rory at 10-1 if I was already on him heavy at 11-2 and wanted to try and get more value.
Other Favorites:
Dustin Johnson (now 18-1; was 16-1)
Sergio Garcia (now 18-1; was 40-1)
Bubba Watson (now 20-1; was 10-1)
Phil Mickelson (now 25-1; was 18-1)
Do you trust Sergio Garcia? If you do, more power to you, but I'll steer clear of that bet -- I'll admit that he looked excellent today. Same thing I said about Rory applies here to Bubba, I wouldn't touch that unless I was already on him heavy. I really don't love the value for any of these guys and think you can get better odds elsewhere.
Contenders:
Ernie Els (now 30-1; was 200-1)
Patrick Reed (now 35-1; was 33-1)
Paul Casey (now 35-1; was 60-1)
Charley Hoffman (now 40-1; was 80-1)
Russell Henley (now 40-1; was 100-1)
Ernie Els and Charley Hoffman aren't getting much love for being at 5-under. We've seen Els do this before, where he shows up at a major and seemingly out of nowhere figures his game out. As for Hoffman, he wasn't afraid of the stage as the first guy out there Thursday morning.
I like really any of these five as value bets.
The Long Odds:
Bill Haas (now 66-1; was 100-1)
Billy Horschel (now 66-1; was 50-1)
Webb Simpson (now 66-1; was 125-1)
Haas seems like the best value here, as I trust his game more than the other two here. He and Simpson are only five back, and Horschel's still in the hunt at 2-under. Any of these guys could be solid value bets.
The one named Tiger Woods:
Tiger Woods (now 66-1; was 20-1)
Don't do it. He's playing pretty well, and better than I think most of us expected with his short game, but don't do it. He's still not in tournament form and he won't get to a point where he can make up a nine-shot deficit on Jordan Spieth in the next three days -- or probably ever.
