For much of the 2025 season, the defending World Series champion Los Angeles Dodgers were the heavy favorite to repeat, anchoring the top of the odds board. But as the season wound down, they hit some turbulence in their play, and that has opened the door for more teams.

In recent lines, the Philadelphia Phillies have threatened to take over for L.A. as the betting favorite. Plus, the Milwaukee Brewers fashioned the best record in baseball. The Dodgers are still in the favorite for now, albeit by a much smaller margin in many books.

Other clubs have also emerged as serious threats according to the latest markets. In the American League, the Toronto Blue Jays and New York Yankees often appear in the top tier of teams. And don’t overlook the Seattle Mariners — some lines list them as having the best odds among AL teams to reach the Fall Classic or even win it all.
