Ranking the Reigning Division Champions' Chances of Repeating
The 2026 MLB season is fast approaching, and the excitement is palpable as the Yankees and Giants gear up for their opening day on March 25th. To build anticipation, we're kicking off our annual preview series, offering a deep dive into each division, analyzing key topics, and predicting the upcoming season.
Today, we focus on the reigning division champions and their prospects of repeating their success. How many teams managed to defend their division titles last season? Surprisingly, the number is quite high, but not unprecedented.
In the past eight seasons, the following number of defending champions have gone on to win again:
- 2025: 4
- 2024: 3
- 2023: 3
- 2022: 2
- 2021: 2
- 2020: 3
- 2019: 3
- 2018: 4
This data reveals that six out of the last eight seasons have seen at least three repeat division champions. As we approach 2026, the question arises: Will this trend continue?
Let's examine the six division champions from the previous season, ranked by their likelihood of retaining their division title.
- Dodgers (NL West)
- Record: 93-69
- Margin of Victory: 3 games over Padres
Despite their impressive record, the Dodgers face skepticism due to their aging roster. Many key players are in their 30s, and their outfield depth is a concern unless they make significant additions. Their division win was their narrowest since 2018, indicating a potential challenge from rival teams.
- Mariners (AL West)
- Record: 90-72
- Margin of Victory: 3 games over Astros
The Mariners, after winning their first division title in 21 years, are favorites in the AL West. Their competition, including the Astros, Rangers, A's, and Angels, is less formidable. With a healthy pitching staff, MVP candidates, and potential offensive upgrades, Seattle is poised for another successful season.
- Phillies (NL East)
- Record: 96-66
- Margin of Victory: 13 games over Mets
The Phillies faced challenges last season, with key players underperforming. However, they still secured a division title. This season, they face a tougher competition with the Braves, Mets, Marlins, and Nationals. Philadelphia remains the division's top team, motivated to win and secure their title before their roster ages.
- Blue Jays (AL East)
- Record: 94-68
- Won Tiebreaker over Yankees
The Blue Jays have improved since last season, with notable additions like Dylan Cease and Tyler Rogers. However, the AL East is a highly competitive division. Teams like the Red Sox, Orioles, and Rays are making significant moves, while the Yankees are desperate to win. Toronto remains the favorite, but they'll face strong challenges.
- Brewers (NL Central)
- Record: 97-65
- Margin of Victory: 5 games over Cubs
The Brewers, despite their recent success, face skepticism. They might trade their ace, Freddy Peralta, and their success last season was a result of favorable circumstances. The Cubs, Reds, and Pirates are expected to improve, making the Brewers' path to repeating their title more challenging.
- Guardians (AL Central)
- Record: 88-74
- Margin of Victory: 1 game over Tigers
The AL Central division is a wildcard. Every team, except possibly the White Sox, has significant questions, especially offensively. The outcome feels like a roll of the dice, with no clear favorite. The Royals, Twins, Tigers, and White Sox all have their strengths and weaknesses, making this division's outcome highly uncertain.
In conclusion, the 2026 season promises exciting competition as reigning champions aim to defend their titles. While some teams have clear advantages, others face challenges, making the race for division supremacy a thrilling prospect.
