The Chicago Cubs enter spring training as the consensus favorite to win the World Series, as short as 4-1 at some Las Vegas sportsbooks.

The Cubs are 4-1 to win the World Series at the Westgate SuperBook. No other team has odds in the single digits. The Los Angeles Dodgers and Houston Astros are next at 10-1, followed by the New York Mets and Boston Red Sox at 12-1.

The Cubs opened at 10-1 at the SuperBook and attracted steady action to trim their odds down to 4-1. That's the shortest preseason odds any World Series favorite has had in the last four years at the SuperBook. But it hasn't stopped anyone from betting them.

More bets and more money have been placed on the Cubs than any other team at multiple sportsbooks. It's not really close. Editor's Picks Latest futures odds

Twice as much money has been bet on the Cubs than any other team at the SuperBook. The San Francisco Giants have attracted the second-most money, followed by the Dodgers.

The MGM has already written more than 2,500 tickets on the Cubs to win the World Series. That's four times as many bets as the next-closest team, the Mets, have attracted and 25 times more than six teams with the fewest bets: The Miami Marlins, San Diego Padres, Tampa Bay Rays, Milwaukee Brewers, Colorado Rockies and Atlanta Braves.

"It's amazing to see how many people are betting the Cubs," MGM assistant manager Jeff Stoneback said. "Every year, there are always a lot of tickets. Now that they're good, you can basically double that. You get the people that are betting them just because they're the Cubs and the people who are betting them because they actually think they're going to win. That's increased the ticket amount."

The SuperBook opened the Cubs' season win total at 93.5. They are the only team with a season win total in the 90s. The sportsbook at the Atlantis Casino in Reno opened the Cubs' win total at 89 and took enough action on the over to move the number up to 93.

"We have not taken any under wagers [on the Cubs] at this point," Atlantis sportsbook director Steve Mikkelson said Monday.
