As the 2026 MLB season approaches, baseball fans are buzzing with anticipation. But here’s the burning question: Can last year’s division winners do it all over again? With the Yankees and Giants set to kick things off on March 25, we’re diving into our annual preview series, dissecting the chances of each reigning division champion repeating their success. And trust me, this is where it gets intriguing.
First, a quick trivia challenge for you: How many teams managed to defend their division titles in both 2024 and 2025? The answer might surprise you—it’s not uncommon, but it’s no walk in the park either. Over the past eight seasons, we’ve seen at least three repeat champions in six of those years. But will 2026 follow suit? Let’s break it down.
Here’s a ranked look at last season’s six division winners and their odds of staying on top. (Each team is listed with their 2025 record and division margin of victory.)
1. Dodgers (NL West)
93-69, 3 games over Padres
The Dodgers are a powerhouse, no doubt, but here’s where it gets controversial: their age and outfield depth could be their Achilles’ heel. With key players in their 30s and an underwhelming outfield projection, they’re not as invincible as they once seemed. Last season’s narrow division win compared to previous years raises eyebrows. Yet, they’re the two-time defending World Series champs, and their ability to make game-changing moves can’t be ignored. Are they still the team to beat? Absolutely—for now.
2. Mariners (AL West)
90-72, 3 games over Astros
After breaking their 21-year division title drought in 2025, the Mariners are riding high. With a healthy pitching staff, MVP contenders Julio Rodríguez and Cal Raleigh, and a full season of Josh Naylor, they’re the clear favorites. But here’s the part most people miss: their division rivals are in disarray. The Astros are rebuilding, the Rangers are in limbo, the A’s have pitching woes, and the Angels are a non-factor. Can Seattle capitalize again? It’s looking likely.
3. Phillies (NL East)
96-66, 13 games over Mets
The Phillies cruised to a division title last season despite underperformance from key players like Bryce Harper and Aaron Nola. And this is where it gets interesting: while the Braves, Mets, Marlins, and Nationals are all threats, Philadelphia’s roster still stands out. They’re motivated to win now before their window closes. Will 2026 be their year? It certainly feels like it.
4. Blue Jays (AL East)
94-68, won tiebreaker over Yankees
The Blue Jays are better than ever, with Dylan Cease, Tyler Rogers, and Kazuma Okamoto bolstering their lineup. But here’s the catch: the AL East is a gauntlet. The Red Sox, Orioles, Rays, and Yankees are all loading up. Toronto might be the best team in the division, but they’ll face relentless competition. Can they rise above the chaos? It won’t be easy.
5. Brewers (NL Central)
97-65, 5 games over Cubs
The Brewers are the perennial underdogs who keep proving everyone wrong. Here’s the controversial take: despite winning three straight division titles, they’re still doubted. Trading Freddy Peralta or relying on last season’s breakout stars could backfire. Yet, they’ve defied the odds before. Will they do it again? History says yes, but this season feels different.
6. Guardians (AL Central)
88-74, 1 game over Tigers
The AL Central is a toss-up. And this is the part most people miss: every team in this division (except maybe the White Sox) could take a step back. The Guardians won last season, but can they repeat? It’s anyone’s guess. Will the Royals, Twins, or Tigers step up? Or will the Guardians squeak by again? Your guess is as good as mine.
Now, here’s the question for you: Which division winner do you think has the best shot at repeating? And which one is most likely to fall short? Let’s hear your thoughts in the comments—this debate is far from over!
