The Major League Baseball season is back, with the 2026 campaign officially underway across stadiums in the United States and Canada. The regular season typically begins in late March and runs through September, followed by the postseason in October. This year brings another full schedule of games, with teams competing for position, momentum, and a chance to reach the World Series.
As the season unfolds, attention naturally turns to the biggest rivalries in the league. These matchups often bring more intensity, especially when teams are close in the standings or have a long history together. Betting odds and preseason expectations also give a clearer picture of which teams are seen as strong contenders. That combination of rivalry and expectations helps shape how the 2026 season is viewed from the start.
Baseball’s Historic Rivalry
The rivalry between the New York Yankees and the Boston Red Sox is one of the most well-known in all of sports. The rivalry dates back more than a century, with many defining moments in baseball history tied to these two teams. One of the most significant came in 1919, when Babe Ruth was sold by the Boston Red Sox to the New York Yankees, a move that helped launch decades of dominance for New York.
However, the gap between the two teams is more noticeable when looking at sportsbook odds this season. The Yankees are seen as one of the top contenders for the championship, while the Red Sox are placed much lower. It’s mainly because the New York Yankees have a deeper lineup and a more stable pitching group. On the other hand, the Boston Red Sox are still in more of a rebuilding or transition phase.
The Oldest West Coast Feud
The Los Angeles Dodgers and the San Francisco Giants also share one of baseball’s oldest rivalries, dating back to their time in New York in the late 1800s. Back then, the Dodgers were in Brooklyn, and the Giants played in Manhattan, so they were already close neighbours. Because of that, their fans interacted often, which naturally created tension between the two sides.
Right now in 2026, the clear top team based on odds and expectations is the Los Angeles Dodgers. They are consistently listed as the main favourite to win the World Series, usually around +200 odds, which is much shorter than those of any other team. That means sportsbooks see them as the strongest overall team going into the season. They also have one of the deepest rosters, with star players across both hitting and pitching.
A Clash of Powerhouses
The Los Angeles Dodgers have a long-running rivalry with the San Francisco Giants as well. Both teams originally played in New York City, where they were already close rivals and faced each other frequently. That early proximity helped fuel tension between the fanbases, and over time, it developed into one of baseball’s strongest rivalries. When they moved to California in 1958, they carried that history with them, so the rivalry never reset, it simply changed locations.
As mentioned, Dodgers As mentioned, the Los Angeles Dodgers are seen as one of the strongest teams in 2026 based on current odds and expectations. The Giants are not always viewed at the same level in terms of overall strength, but they still play the Dodgers multiple times each season. These games can affect standings, especially within their division, so each matchup still matters.
The Subway Series Rivalry
The New York Yankees have also built a strong cross-town rivalry with the New York Mets, known as the Subway Series. Fans can literally take the subway to travel between the Bronx (where the Yankees play) and Queens (where the Mets play). Since both teams are based in New York City, the rivalry feels local and personal. Fans often split loyalties across the city, which adds extra excitement to each game.
This year, the Yankees are stronger. The Mets are still competitive, but they are seen as less consistent. There are stretches where the lineup produces runs and the pitching looks solid, but those are sometimes followed by periods where performance drops off. The Mets often rely heavily on a few key players, so when those players are not performing at a high level or miss time, the overall team output can dip quickly.
A Longtime Matchup
Another rival of the Los Angeles Dodgers is the St. Louis Cardinals. This is mainly because of repeated postseason matchups. Over the years, they have met in several important playoff series, where each game carried high stakes. These moments often decided who would move forward, which naturally built tension between the teams.
The St. Louis Cardinals are generally seen as having moderate chances in 2026, especially when compared to a leading team like the Los Angeles Dodgers. Based on typical odds, they are not among the top favorites, but they are also not at the bottom. This places them in a middle tier, where a strong stretch of games could quickly improve their position.
Rivalries Take Center Stage in 2026
The 2026 Major League Baseball season combines championship contenders with some of the sport’s most iconic rivalries. The Los Angeles Dodgers continue to lead the field, making every high-profile matchup, especially against the San Francisco Giants, feel even more significant in the playoff race. Meanwhile, the rivalry between the New York Yankees and Boston Red Sox remains one of baseball’s biggest attractions because of its deep history and decades of unforgettable moments.
The Subway Series between the Yankees and the New York Mets also adds another layer of intensity, fueled by city pride and passionate fanbases. With playoff implications, star players, and historic rivalries all colliding, the 2026 MLB season continues to deliver must-watch matchups throughout the year.
