Sportsbook.com isn't the most reliable book out there, but they often offer futures lines that are hilariously out-of-whack and even inconsistent with the other lines at their own book.
Let's say you want to bet some Astros futures. You can currently get them at 10-1 to win the Wild Card, 150-1 to win the NL Pennant...or you can go to "World Series Possible Matchups" and bet the Field. This gives you the Astros, Marlins, AND Cardinals to win the NL, complete with a 1000-1 payoff. Even ignoring Florida and St. Louis, the Astros would have to be 90-1 dogs in the playoffs for the Wild Card and Field lines to be consistent with one another.
The Marlins show an interesting and different pattern. Florida is 250-1 to win the NL (note that this is still much worse than the 1000-1 Field payoff which includes the Marlins) but 300-1 to win the Wild Card, which is their only possible route into the playoffs! They'd have to be even better than a lead pipe lock in the playoffs for this to make any sense.
Speaking of the NL Wild Card lines, how about the Brewers at -300? Collapse be damned! Milwaukee is 5-1 to win the NL, but a whopping 50-1 to win the World Series, making them 7.5-1 dogs in the Fall Classic, should they get there. Apparently the AL is just that good.
Looking to hedge your bet on Tampa Bay to win the AL East? No bookie is offering a fair price on the Red Sox at this point; you might get +250 when the true odds are more like +400. No one, that is, except Sportsbook.com, who offers you the same bet in the guise of Tampa to win the Wild Card at +500.
Lastly, if you're betting the Wild Cards, be careful not to put any dollars down on the White Sox, Twins, D-backs, or Dodgers, who all have odds posted despite being mathematically eliminated from the race. The Dodgers are especially funny, as their payoff is only 20-1 even though they've been dead for several days now.
