Early-Season MLB 2026: Senga, Moniak, the Dodgers — And Why Baseball's Grinding Schedule Is the Best Model for Long-Term Athletic Health

The First Stories of the Season

Two weeks into the 2026 MLB season, the early narratives are forming in the way they always do in April — some of them will last until October, most of them will be forgotten by Memorial Day.

Kodai Senga looked like the pitcher the Mets paid for in a 5-2 win over the San Francisco Giants. His splitter produced weak contact from first pitch to the seventh inning, his command was precise, and his velocity was where it needs to be for a full season. After injury concerns limited his 2024 and disrupted his 2025, there will be cautious optimism in the Mets' dugout — and in Senga's camp — about what the next six months could produce.

In Colorado, Mickey Moniak delivered the kind of game that creates a fan base overnight. Two home runs against the Phillies to power the Rockies to a 4-1 series win. Power from a player whose defensive reputation is what most scouts lead with — moments like this are why teams keep athletic, versatile outfielders on their rosters through down stretches.

The Dodgers got their fifth comeback win of the young season against Washington. Whether that reflects genuine resilience or simply the advantages of outspending every team in baseball is a debate worth having in late September, not early April. What matters now is that they are winning the games they are supposed to win, and occasionally the ones they aren't.

At Yankee Stadium, rain. The sport waits for no one, but it will wait for weather. The Cubs and Guardians played a doubleheader. Jo Adell made a defensive play in Anaheim that will be replayed until it's replaced by another one.

It is April. There are 162 games.

The Schedule That Changes Everything

No major professional sport places physical demands on its athletes quite like Major League Baseball — not in individual game intensity, but in cumulative load over time.

An MLB regular season runs from late March through late September: 162 games in roughly 187 days, with the postseason potentially adding another 15 to 20 contests for the teams that advance. Players are on the field virtually every day. Travel schedules cross multiple time zones in the same week. A starting pitcher who throws 200 innings over a season accumulates a physical tax on the shoulder, elbow, hip, and core that has no real parallel in any other sport's regular season.

The teams that win in October are not always the most talented teams in April — they are often the teams whose players are healthiest in September. And the players who are healthiest in September are almost universally the players who took their recovery work as seriously as their preparation work from the first day of spring training.

This is the fundamental insight that separates athletes with long careers from those with abbreviated ones. It is not about training harder. It is about the invisible work — the stretching, the mobility maintenance, the ice, the sleep, the deliberate management of accumulated physical cost — that makes continued performance possible.

What Pitchers Know That Everyone Else Should

Baseball's most physically vulnerable position is also its most preparation-disciplined. Starting pitchers — particularly at the major league level — have perhaps the most structured, evidence-based physical maintenance protocols of any athletes in professional sport.

The reason is simple: a starting pitcher who ignores shoulder and elbow health for two months will have surgery. The consequence is concrete enough that the system enforces preparation.

A typical MLB starter's between-start routine includes extensive shoulder external rotation work — exercises that strengthen the rotator cuff in its most vulnerable positions and maintain the range of motion required for a healthy throwing motion. It includes thoracic spine mobility work, because a stiff thoracic spine forces the shoulder to compensate during the throwing motion in ways that increase labrum and UCL stress. It includes hip and lower body work, because the power of a pitched ball originates in hip rotation, and a restricted hip transfers that deficiency directly to the arm.

This is not optional maintenance for a pitcher. It is the job. The five-day rotation exists partly to allow this work to happen — two to three days of physical preparation and maintenance for every day of pitching.

Position players have been slower to adopt this level of physical discipline. The daily demands of the position player schedule — field work, batting practice, the game itself — create a different kind of cumulative fatigue than pitching. But the principle is identical: the players who maintain hip mobility, thoracic rotation, and shoulder health through daily targeted work are the ones who finish seasons healthy and perform in September.

The Three Areas Baseball Destroys — And How to Protect Them

Six months of professional baseball creates characteristic restriction patterns. The three areas most commonly degraded by the season's cumulative load are shoulder external rotation, hip mobility, and thoracic spine health.

Shoulder external rotation degrades in pitchers through the repeated internal rotation demands of the throwing motion. The posterior capsule thickens and tightens. External rotation range — measured as how far the arm can rotate backward in the cocked throwing position — decreases. When this restriction becomes significant, the shoulder compensates by elevating during the throwing motion, creating impingement risk and reducing velocity. The standard intervention is the sleeper stretch and cross-body shoulder stretch, performed daily regardless of game schedule.

Hip mobility — particularly hip internal rotation on the stride leg and external rotation on the push-off leg — is fundamental to the rotational mechanics of throwing, batting, and fielding. Six months of the same repetitive rotational movements, predominantly in the same direction, creates characteristic asymmetries: one hip becomes tighter than the other, the pelvis begins to rotate into a fixed position, and the lower back compensates. This is as true for position players as for pitchers.

Thoracic spine health follows the pattern described in this site's other mobility content: accumulated forward flexion from field positioning and batting stance progressively limits extension and rotation. A hitter whose thoracic spine cannot rotate freely to the lead side will compensate with the lumbar spine — a common mechanism for the oblique strains that send hitters to the injured list in April and May.

The interventions for all three are not complicated. They are simply maintenance: daily shoulder stretching, daily hip mobility work, daily thoracic extension and rotation. Fifteen minutes at the end of every workout. Less exciting than extra batting practice. More valuable than most of the things athletes do instead.

The 162-Game Lesson

There is a version of athletic ambition that is entirely focused on the acute — training harder, performing better on a specific day, breaking through in a single session. This version is useful in a sprint. It is destructive in a marathon.

Baseball, more than any other sport, demands the marathon mindset. The seasons of Mickey Moniak, Kodai Senga, and every other player who performs into September are built on months of decisions that compound invisibly. Not just training decisions — recovery decisions. Sleep. Nutrition. Daily mobility maintenance. The boring, repetitive, never-headline-generating work of keeping a body functional under accumulated load.

The players you watched this weekend — the ones hitting home runs and throwing sharp splitters in the early spring air — did not arrive at their physical readiness by chance. They built it, maintained it, and will spend the next six months working to keep it.

The same principle applies at every level of athletic participation. Volume beats intensity over time. Consistency beats heroism. The ability to show up the next day — healthy, mobile, ready — is a skill, and it is built through exactly the kind of daily maintenance work that feels unnecessary on any given day and essential in aggregate.

It is April. The season is long. Take care of your body the way the best athletes in baseball take care of theirs.
