Dodgers are 2016 World Series favorites

The Los Angeles Dodgers head into what could be an active offseason as the favorites to win next year's World Series.

The Dodgers are 8-1 at the Westgate Las Vegas SuperBook, followed by the Chicago Cubs, New York Mets, Toronto Blue Jays and Washington Nationals, who are all 10-1.

Don Mattingly stepped down as manager of the Dodgers on Oct. 22 after Los Angeles was eliminated from the postseason by the Mets in the National League Division Series. The Dodgers' co-ace starter Zack Greinke is expected to opt out of his contract and fetch big money as a free agent.

The newly-crowned World Series champion Kansas City Royals are 18-1 and facing a critical offseason. Starting pitcher Johnny Cueto and second baseman Ben Zobrist are free agents, and left fielder Alex Gordon has a player option. The Houston Astros (12-1), Pittsburgh Pirates (12-1) and New York Yankees (16-1) are among the teams with better odds than the Royals, who have won the past two American League pennants.

The Boston Red Sox, like the Royals, are 18-1.

The defending National League champion Mets also have some big decisions looming. Slugger Yoenis Cespedes is a free agent, and postseason star Daniel Murphy could depart.

The Nationals, who began the 2015 season as the World Series favorites, could see significant turnover, with Jordan Zimmermann, Ian Desmond and Denard Span bound for free agency.

Toronto starter David Price is another free agent who could impact the World Series odds over the next five months.

The Philadelphia Phillies, who won an MLB-low 63 games this year, are the biggest long shots on the board. The Phillies are listed at 300-1.

Two risky bettors have already backed the Phillies, according to Westgate assistant manager Ed Salmons.
