A trio of teams – the Cubs, Red Sox and D-backs – have garnered the bulk of the offseason headlines thus far.

Yes, plenty of teams have made moves to put themselves in a better position going forward, but the three teams mentioned above have made the biggest, most significant moves and the betting lines reflect that.

On November 2, the day after the World Series concluded, Bovada, an online casino and sportsbook, posted odds for the 2016 World Series. The Cubs (11/1) were the odds-on favorite while the Red Sox (20/1) were in the middle of the pack and the D-backs (50/1) seemed like a long shot.

Fast forward through the Winter Meetings, into the middle of December, and plenty of things have changed.

The Cubs are still the favorites, but the odds are now 8/1 after the club strengthened the rotation and signed John Lackey, in addition to bolstering an already potent lineup with the additions of Ben Zobrist and Jason Heyward.

Boston got a head start on the off-season wheeling and dealing when it traded four prospects to San Diego in exchange for Craig Kimbrel. The Kimbrel trade was a big move that strengthened a ‘pen that finished the season with a 4.24 ERA, 26th in all of baseball. However, it turns out it was just a precursor as Dave Dombrowski still had some tricks up his sleeve.

The Red Sox made another big splash when they inked David Price to a monster contract and as a result, their World Series odds jumped from 20/1 to 9/1.

But perhaps the biggest off-season shocker took place just before the Winter Meetings when Arizona landed Zack Greinke. Not only did the Greinke signing give a tremendous boost to Arizona’s starting rotation, but it also subtraced an ace from the Dodgers’ staff and kept the Giants, a division rival and the other finalist in the Greinke sweepstakes, from acquiring the superstar.

Of course, once the D-backs added Greinke it was a clear sign that the team was in “win now” mode, so Dave Stewart and Tony La Russa went out and made another bold move, trading for Shelby Miller.

The D-backs finished second in the National League in runs scored a season ago and added two quality arms to the rotation which is why the odds went all the way from 50/1 to 20/1.

Although the Giants missed on Greinke, the club added Jeff Samardzija and saw odds swing from 20/1 to 8/1.

While all those changes were significant and interesting, there is still plenty of offseason left, which means time for more deals (what happens if the Cubs get another pitcher?).
