April is over. The lies are done. Now the real MLB season begins.
There is something almost ceremonial about the first of May in baseball. Spring training optimism has been stress-tested. April’s small sample sizes have started hardening into patterns. The teams that looked like contenders on paper — and then looked horrific on the field — have run out of excuses. The calendar flips, and suddenly everything feels urgent. Check the MLB standings right now and you will see a league already sorting itself into winners, pretenders, and outright disasters. May is when we stop pretending and start believing what we’re actually seeing.
So what are the questions that matter most heading into the second month? What storylines will shape MLB games from here through the summer and, eventually, determine who is playing in October? Here are five. They’re not all comfortable. But they’re all necessary.
1. Can the Astros, Mets, Phillies, and Red Sox Actually Turn This Around?
Let’s be blunt. These were not supposed to be bad teams.
The Mets sit dead last in baseball at 10-21, hemorrhaging runs at a rate that would embarrass a Little League squad — a minus-35 run differential after barely a month of play. The Phillies are 12-19 with a staggering minus-45 run differential, the worst in the league. Houston, a franchise that spent the better part of a decade as the AL’s gold standard, is 12-20 with a pitching staff posting a 6.08 ERA. No other team in baseball has an ERA worse than 5.11. Let that sink in. The next-worst team is nearly a full run better per game. The Red Sox, meanwhile, are 12-19 and sputtering.
Already, two managers have been fired. The Phillies made their move. The Red Sox followed. Carlos Mendoza in New York looks like he’s managing with a sword dangling over his head. Joe Espada in Houston probably isn’t sleeping well either, though it’s worth noting that the mess in the Astros’ rotation predates anything he could have controlled MLB.
And yet — baseball is long. Brutally, mercifully long.
Cast your mind back to last May 25. The Blue Jays were 25-27, seven games out in the AL East. By the end of the regular season, they had the best record in the American League. They went on to reach the World Series — the MLB Fall Classic 2025 — as one of the sport’s most surprising stories. It can happen. Teams do climb out of holes this deep.
But there’s a difference between “it’s possible” and “it’s likely.” The Mets, Astros, Phillies, and Red Sox have already burned through most of their margin for error. May can’t just be better. It has to be dramatically better. Every series on the MLB schedule matters more now than it did three weeks ago. Win streaks aren’t a bonus anymore — they’re a survival requirement.
2. Who in the American League Is Ready to Challenge the Yankees?
The AL is, to put it diplomatically, a mess below the top.
Three teams — the Athletics, Rays, and Yankees — have winning records on May 1. Three. Out of fifteen. The MLB run differential leaderboard tells an even starker story: the Yankees sit at plus-47, and then there’s a considerable drop before you reach the Tigers at plus-9 and the Rangers at plus-8. The rest of the league is bunched together in a kind of competitive mediocrity that would be concerning if it weren’t also somewhat fascinating.
Here is the strange part about the Yankees’ dominance: it’s happening without Gerrit Cole and Carlos Rodón, who have combined to throw zero pitches in the majors. Zero. Their rotation — even without two of their most important arms — leads baseball in ERA (3.11), FIP (3.48), xERA (3.42), and WAR. Cole and Rodón are on minor-league rehab assignments. They are coming. When they arrive, New York’s lead in the AL could become something genuinely obscene.
So which team steps up to at least make it interesting?
The Blue Jays (14-17) are trending the right direction after getting healthier. The Mariners (16-16) just won six of seven and look increasingly like the team that was five outs from the pennant last October. The Rays (18-12), somehow, just keep grinding. The Tigers at 16-16 have flashed talent without ever stringing anything together.
One of these teams — maybe more than one — needs to seize the moment in May. The AL Central and AL West are wide open, which means even a modest run in the next 30 days could hand a team a division lead they might never relinquish. For anyone tracking MLB daily, the AL race outside of New York is the most watchable kind of chaos: anyone can make a move, and everyone knows it.
3. Can Mason Miller Actually Be This Dominant for a Full Season?
There is “good closer” and then there is whatever Mason Miller is doing right now.
The San Diego Padres’ closer is technically in a slump. He gave up his first two runs of the season earlier this week. He’s struck out just one batter across his last 18 faced. “Slump,” in this case, is a deeply relative term — because in April alone, Miller fanned 28 of the first 39 hitters he saw. He leads baseball with 10 saves. He has 29 strikeouts in just 15⅓ innings. His April strikeout rate of 53.7% placed him fifth on the all-time single-month list for relievers with a minimum of 15 innings, behind only Josh Hader in April 2018 (62.9%), Corey Knebel in September 2018, Eric Gagne in August 2003, and Adam Ottavino in April 2018.
The combination driving all of this? A 103 mph fastball and a slider that hitters simply cannot identify. Opposing batters aren’t just missing — they’re missing badly, flailing at pitches they never had a realistic chance of squaring up.
For context on how historic a full season could look: only two pitchers in baseball history have struck out more than half their batters faced over a full season with at least 60 innings pitched — Craig Kimbrel with the 2012 Braves (50.2%) and Edwin Díaz with the 2022 Mets (50.2%). Miller, at his current clip, isn’t just threatening to join that list. He might lap it.
Nine relievers have won the Cy Young Award in MLB history, but only once since 1995 — Eric Gagne in 2003. The best relief seasons of recent memory, including Zack Britton in 2016 and Emmanuel Clase in 2024, topped out at third place in the voting. Miller is carving a path toward something genuinely unprecedented.
And then there’s the team dimension. San Diego is 19-11. They’re 14-0 when Miller enters with the lead or the MLB game tied. They’re 7-2 in one-run and two-run games. Without a truly elite rotation and with a middling offense, the Padres’ entire margin for winning close games flows through one man’s right arm. If ESPN MLB analysts start throwing MVP conversation around a reliever, it won’t be hyperbole. It’ll be a legitimate debate.
4. Which Surprise Teams Are the Real Deal?
Every season has them — the clubs nobody circled on their preseason predictions who show up in May actually competing. This year’s batch is notable for a few reasons, not least because some of these teams were historically terrible just months ago.
The Chicago White Sox are 14-17. That number looks pedestrian until you remember they lost 121 games in 2024 and 102 in 2025. They’re not good — but they’re no longer a guaranteed win for anyone. The Colorado Rockies are 14-18. Last year at this point, they were 14-57. The Washington Nationals, who lost at least 91 games in five consecutive seasons, are sitting at 15-17 while averaging 5.47 runs per game — a figure bettered only by the Atlanta Braves’ 5.53. The Marlins, perpetual also-rans, are a pesky 15-16.
But the most eyebrow-raising story of the young season might be the St. Louis Cardinals, who entered 2026 in the middle of a rebuild. President of baseball operations Chaim Bloom traded away Willson Contreras, Brendan Donovan, and Sonny Gray for prospects over the winter. These were not moves that screamed “contend now.” And yet: the Cardinals are 18-13. They are grinding opposing teams into the dirt, winning close games, and generally being the kind of annoying, disciplined club that will always find ways to beat you if you’re not careful.
MLB Will any of these teams be relevant when the calendar turns to September and MLB positioning is on the line? Probably not all of them. Maybe not most. But one or two clubs from this group will hang around far longer than the analytics say they should. Baseball is full of those stories. It wouldn’t be baseball without them.
5. How Ugly Will the Early CBA Talks Get?
It’s coming. This month, MLB and the MLB Players Association are expected to begin preliminary discussions about a new collective bargaining agreement. The current CBA expires December 1. A deal will not be reached in May — that much is certain. What will emerge, slowly, is the shape of each side’s demands. And those demands, when they leak, will be significant.
The owners want a salary cap. They’ve framed the conversation around competitive balance, pointing to the league’s haves and have-nots as evidence that the current system isn’t working. There’s a certain irony to that argument when you look at MLB sites right now and see that the Mets and Phillies — two of the five highest payrolls in baseball — are languishing near the bottom of the standings. High spending does not automatically produce success. That argument, however, rarely stops an owner from making it.
The players will push back hard on a cap. They’ll want earlier access to salary arbitration, higher minimum salaries, and more guaranteed paths to free agency for younger players. They’ve watched too many teams use “rebuilding” as a synonym for “suppressing payroll,” and they’re tired of it.
Here’s the reality: nobody checking MLB wants to spend May reading about escrow calculations and service time manipulation. The 2026 season, from a pure baseball standpoint, is genuinely entertaining. The standings are wild. The individual performances are historic. The last thing any fan needs is CBA posturing crowding out actual baseball coverage.
A lockout in December is not inevitable. But it’s a possibility. The owners and players have, historically, an impressive talent for turning manageable disagreements into prolonged, expensive standoffs that damage the sport’s relationship with its own audience. Hopefully, this time is different. Hopefully, the leaks are minimal, the negotiations stay out of the headlines, and everyone keeps their focus on the game being played rather than the game being negotiated MLB.
The Bottom Line
May won’t answer everything. But it will answer a lot.
It will tell us whether the Mets and Astros are capable of saving their seasons or whether we’re watching the slow unraveling of expensive, misbuilt rosters. It will reveal whether a team in the American League has the courage and consistency to step out of the Yankees’ shadow. It will show us whether Mason Miller is a historical anomaly or a historical figure in the making.
Most of all, it will do what May always does in baseball. It will tell us the truth. And some of those truths — for some of these teams, some of these managers, some of these MLB players — are going to hurt.
