Spring training is finally in full swing, and as we get closer to Opening Day 2026, the initial buzz is giving way to real drama. While the Los Angeles Dodgers are expected to be dominant, there are several other MLB storylines developing into full-blown mysteries that will dictate the shape of the 2026 season. Here are five storylines heating up in MLB right now that you need to watch.
The Top MLB Storylines Heating Up Right Now
 1. The “Polar Bear” in Baltimore
The Baltimore Orioles made their biggest statement of the offseason by stealing Pete Alonso away from the New York Mets, signing him to a five-year, $155 million deal. After years of relying on homegrown talent, Baltimore now has a proven, elite power hitter sitting in the middle of a lineup featuring Gunnar Henderson and Adley Rutschman.
The tension isn’t about whether Alonso can hit, it’s about how he integrates into a young clubhouse and handles the pressure of being the guy in a loaded AL East. Early reports suggest he is already taking a leadership role, but all eyes are on how Baltimore’s lineup looks with him at the heart of it. If he picks up where he left off, the O’s could bounce back and possibly overtake the New York Yankees.
2. Tarik Skubal’s Contract Year
Tarik Skubal enters 2026 as the undisputed king of the AL Central, fresh off a 2025 season where he was arguably the best pitcher in baseball. Now, he’s in a contract year with the Detroit Tigers, making his every move a massive storyline.
The question isn’t just about whether he can win his third consecutive Cy Young. It’s about his future. Will the Tigers compete as expected, or will they struggle and consider dealing Skubal at the deadline? Every start he makes is an absolute, must-see show, and his performance will set the tone for the entire AL landscape.
3. The Chicago Cubs’ Aggressive Makeover
After losing outfielder Kyle Tucker to free agency, the Chicago Cubs were relatively quiet early in the offseason. That changed when they secured third baseman Alex Bregman to a five-year, $175 million deal.
The Cubs are clearly attempting to force themselves into the NL Central conversation, pairing Bregman with a young core that showed promise in 2025. The story here is whether this combination of established veteran leadership and young talent is enough to challenge for the division title or if it’s just another “middle of the pack” move. Early camp vibes are high, but the pressure to win immediately is on.
4. The Los Angeles Dodgers’ “Super Team” Status
The Dodgers won two straight World Series, defeating the Yankees and Toronto Blue Jays in 2024 and 2025. They aren’t just trying to win in 2026, they are trying to cement a dynasty, looking for a three-peat.
With a projected Opening Day payroll of over $300 million and the addition of the star outfielder Tucker, they are undeniably the team to beat. The storyline here is the immense pressure. Anything less than another championship will be viewed as a failure. Can a team with that much success stay hungry, or will the pressure of maintaining a dynasty cause them to crack?
5. The ABS Challenge System Drama
For the first time in MLB history, players have the power to appeal strike-zone judgments of human home-plate umpires by turning to the Automated Ball-Strike Challenge System.
This isn’t just a rule change, it’s a mental game. Teams get two challenges, and the drama is played out on the stadium scoreboard. The real story is how players and managers react to this new power. Do they trust the machine, or do they trust their gut? The first few weeks of spring training are showing that some teams are already using it strategically, while others are still hesitant. This is going to produce incredible, in-game drama.
