Is Your Baseball Team Better Than the Market?

Betting exclusively on your favorite ballclub is about as logical as investing your life savings in the company headquartered nearest your home address. Then again, some people live down the street from Google.

According to the sports book Bodog.com, placing the same $100 wager on your favorite baseball team before every game this season would lose you an average of $336. Even teams with winning records, like the Boston Red Sox or Tampa Bay Rays, would have lost money on the year. Since these teams are good, they're generally favored—which means they pay lower returns when they win.

Not every fan who bets this way would be disappointed. The Los Angeles Angels, for instance, would have paid out a MLB-high $2,128—a return on investment slightly better than what the Dow Jones Industrial Average delivered over that period. The Texas Rangers would win gamblers $1,657, and the Los Angeles Dodgers $934. Those three teams have something in common: They're winning teams that gamblers underestimated.

When too many gamblers bet against a team, bookmakers change the odds to encourage more people to bet the other way. (Bookies like the same amount of money on each side of a bet because they break even on the bet itself, and make a guaranteed profit on the commission.) As a result, the same $100 wagered each day on the underestimated Angels this season paid significantly more than one on the overestimated Red Sox. It's the same reason the Chicago Cubs have won a majority of their games, yet are among the league's worst teams to bet on. The fact that both the Red Sox and the Cubs are popular ballclubs with legions of biased fans doesn't help the odds, either.

Eventually, the underestimated teams start gaining respect, and the gambling world finds an equilibrium. Don't expect bets on the Angels to win quite as much money in the second half of the season, says Richard Gardner, sportsbook manager for Bodog.com. "Bettors have taken notice and the lines have continued to climb," he says.
