2025 MLB League Winner Odds
Becoming a World Series champion is the goal for all MLB teams, but winning a pennant is nothing to brush off. Before teams can fight for a World Series ring, they must first complete the pennant in their respective league, which is another bragging point for fans arguing which franchise is historically better. In 2024, two powerhouse franchises returned to the top as the Yankees and Dodgers broke through to the World Series.
Both teams opened as the favorites to win their respective league in 2025, and with the season entering the end of May, we’ll look at the updated odds for each team to win the AL or NL across all the top sportsbooks in Arizona.

Current American League Favorites
New York Yankees: Strong fundamentals were not something the Yankees had all season, and while they would reach the World Series for the first time since 2009, those fundamental mistakes would be their downfall. While injuries have already started piling up for New York this season, they certainly still have the talent to return to the Fall Classic. So far, the Yankees' offense has proven they can still be high-powered without Juan Soto, as they lead the league in home runs and OPS.
Detroit Tigers: The Tigers burst onto the scene last season and proved they have the potential to be a contender for years to come. Behind a strong rotation led by 2024 Cy Young Tarik Skubal and Casey Mize, who is on a career resurgence. As a pitching staff, the Tigers have the 7th most strikeouts in the league this season, while on offense, guys like Spencer Torkelson, Riley Greene, and Gleyber Torres have helped Detroit rank 6th in OPS and 8th in home runs.
Seattle Mariners: Getting off to hot starts has become common for the Mariners. Of course, the only problem is that they have proven to struggle to sustain any early-season success. With the hopes of shaking that reputation, the Mariners will need their young starting rotation to continue their high level of play and stay healthy. Meanwhile, offensively, Seattle can certainly sustain success all season if their lineup can continue to leave the yard, as they rank 6th in home runs entering the end of May.

Current National League Favorites
Los Angeles Dodgers: The reigning World Series champions returned a ton of crucial pieces for the 2025 season, and to make things even better, they will likely have Shohei Ohtani joining their rotation after he put up an MVP season at DH. LA has always been one of the biggest spenders in the offseason, and this year was no different. With a good mix of returning players and new acquisitions, LA is 2nd in OPS, while their pitching staff, led by Yoshinobu Yamamoto, is 3rd in strikeouts.
Philadelphia Phillies: Talent-wise, the Phillies can stack up with any pitching staff or lineup in the league. With plenty of power riddled throughout the lineup, Philadelphia has started the season with the 5th-best OPS in the league. Meanwhile, on the mound, behind guys like Zack Wheeler, Jesus Luzardo, and Christopher Sanchez, the Phillies are ranked 1st in strikeouts, which has helped them climb into first in the NL East after going 8-2 over their last ten games.
New York Mets: The Mets surprised everyone last season by reaching the NLCS, and they have since surprised everyone again by outbidding the Yankees for Juan Soto. With Soto in the mix, the Mets have one of the better lineups in baseball. While that will undoubtedly put them on a good path for another NLCS appearance, the determining factor for NY this season will be their pitching staff, which has the lowest ERA in the league at 2.82.
