It's pretty rare when a sports book doesn't want your money.

After taking a close look at the odds being set for the 2015 Masters, it's pretty obvious they don't want any action on Tiger Woods anytime soon.

This year will mark the 10th anniversary since Tiger's last win at Augusta National, yet he's currently the No. 2 favorite going in at 12/1, the same odds as Jordan Spieth, last year's runner-up.

Rory McIlroy is the betting favorite at 6/1. Defending champ Bubba Watson starts the year at 20/1 to win a third green jacket.

Seeing the odds just for winning majors, it appears McIlroy's numbers make sense.
0 majors = 5/6
1 major = 8/5
2 majors = 11/2
3 majors = 25/1
Winning Grand Slam = 80/1

Those are on point for a guy who won the past two majors and has shown flashes of dominance we've only seen recently from one other guy ... which is what makes Woods' odds to win such a head-scratcher.

Tiger's major odds:
0 majors = 1/4
1 major = 11/4
2 majors = 20/1
3 majors = 100/1
Winning Grand Slam = 250/1

The 39-year-old former world No. 1, who hasn't won a major since 2008 (on a broken leg), is getting 20/1 odds to win two majors this year? That is the gambling equivalent of waving the white flag yelling, "We have no clue! Please keep your money ... or would you like to try a fun game called Keno?"

Odds information above gathered from GolfOdds.com, but other places you can bet are all over the map.

It appears trying to gamble on golf has worse odds than roulette, unless you're McIlroy's dad.
