The Washington Nationals (93.0) and Los Angeles Dodgers (92.5) have the highest projected season win totals according to numbers posted by the Westgate Las Vegas SuperBook. The Philadelphia Phillies have the lowest (68.5).
Since 2009, just one team won the championship after being installed as the preseason favorite: the 2009 New York Yankees. On Mar. 5 they were plus-300 on the money line and beat the Phillies in six games. Incidentally, Philadelphia was the second favorite that year (plus-850).
In 2013, the oddsmakers were impressed with the Nationals’ 98-win season the year before and moved them from co-favorites with the Angels and Tigers on Dec. 1 (plus-800) to the sole favorite by Mar. 31 (plus-750). The Nats did not qualify for the postseason after posting an 86-76 record.
The World Series winners since 2010 were all at least 20-to-1 long shots in the offseason but no worse than 30-to-1:
- 2010 San Francisco Giants, 25-to-1
- 2011 St Louis Cardinals, 20-to-1
- 2012 San Francisco Giants, 20-to-1
- 2013 Boston Red Sox, 28-to-1
- 2014 San Francisco Giants, 20-to-1
Using that quick-and-dirty guideline, here are the teams in that range (odds provided by Sportsbook.ag as of Feb. 17, 2015) and their projected 2015 win total from Fangraphs.
