Key Stats that Could Define Every NL Team in 2026

Introduction

With the 2026 MLB season on the horizon, it's time to step back from the buzz of free agency and trade rumors and focus on something fundamental: performance metrics. Each National League team hopes to ride the momentum of 2025 into the new season, but the reality is that certain stats will play a crucial role. In this breakdown, I highlight one significant statistic from each team's 2025 season — a number that could essentially make or break their 2026 season.

Arizona Diamondbacks

The Number: 17

The Diamondbacks made headlines with a staggering 17 different pitchers recording saves last season, a record that the earlier 2021 Rays and 2024 Dodgers couldn't approach. Injuries plagued their bullpen, leading to instability and confusion over the closer role. With a record of 27th in bullpen ERA and 29th in win probability added by relievers, the D-backs face a pressing need to solidify their late-game options if they don't want to miss the postseason once again.

Atlanta Braves

The Number: 38

In 2025, Braves shortstops managed to create only 38 runs, the lowest of any position in the majors. As they look to improve, newly signed Ha-Seong Kim provides hope. If he can at least match his 2024 batting average, he may generate a crucial 30-run increase for the Atlanta offense. Solidifying this position could be a deciding factor for the Braves' success in 2026.

Chicago Cubs

The Number: 39.1

The Cubs boasted a position-player WAR of 39.1, ranking them first in the league. However, with key losses like Kyle Tucker in free agency, fans debate whether their offensive firepower can be replicated. Maintaining this level of performance could be integral to their playoff ambitions, making depth across the lineup crucial.

Cincinnati Reds

The Number: 51

The Reds' outfield power was lackluster with just 51 home runs, leaving them with serious gaps in their offense. They recognize the need to boost power, pointing to potential acquisitions like Kyle Schwarber. Finding effective solutions through trades or signings could ensure they remain competitive in a challenging division.

Colorado Rockies

The Number: 119

After suffering 119 losses last season, the Rockies have a mountain of work ahead to change their fortunes. Hiring experienced baseball executives signifies a new direction, but rebuilding won't happen overnight. A 14-win improvement could be their realistic goal, but history indicates that major turnarounds do happen — establishing a promising outlook could be foundational.

Los Angeles Dodgers

The Number: 30.7

With a weighted age of 30.7 years amongst their position players, the Dodgers have the oldest roster in the league. While they've added Edwin Diaz to tackle bullpen issues, concerns loom about age-related declines impacting their performance. The front office must get younger while maintaining productivity — that delicate balance could dictate their outfield performance in 2026.

Miami Marlins

The Number: 62

First basemen for the Marlins recorded the worst RBI total in the majors last season. Year after year, the struggle continues to find a reliable offensive presence at first. Evaluating options like Eric Wagaman could signal a shift. Establishing consistent production at this crucial position should be a priority in their offseason plans.

Milwaukee Brewers

The Number: .279

The Brewers' prowess with runners in scoring position saw them hit .279, resulting in a strong run-scoring season. However, repeating such success is elusive. Historical trends hint at a potential regression looming in 2026 if they can't sustain their high performance metrics. Examining strategies that worked in 2025 could provide insight into the challenges ahead.

New York Mets

The Number: 796

With their starters pitching only 796 innings, Mets' bullpen did heavy lifting early but suffered dramatic declines in productivity due to injuries. Upgrading the rotation should be a critical focus. With promising rookies emerging, ensuring they can carry a heavier workload could be the key to restoring a struggling rotation.

Philadelphia Phillies

The Number: -38

The Phillies' lineup struggled without consistent run contributions from key players aside from Harper, Schwarber, and Turner. With their lineup potentially entering age declines, addressing missing pieces like a left fielder will be paramount to avoid being one-dimensional in a highly competitive league.

Pittsburgh Pirates

The Number: 583

Finishing last in runs scored at 583, the Pirates have long battled offensive struggles. Relying on high draft picks hasn't produced the anticipated results. While promising prospects may emerge, the Pirates must pivot from their organizational woes and sign impactful free agents to give support to their rotation.

San Diego Padres

The Number: 3.03

The Padres' bullpen excelled in 2025, leading the majors with a 3.03 ERA. With major rotation losses anticipated, success hinges on repeating this level of dominance from their relievers next season. They'll need depth in the bullpen — stepping up will be crucial for any chance at contention.

San Francisco Giants

The Number: 52

For the Giants, the lack of power from left-handed hitters is glaring, ranking last in home runs as a key metric. With roster adjustments needed, adding impactful left-handers is pivotal to enhancing offensive capability. Focused scouting and smart trades might fill this gap effectively in the upcoming offseason.

St. Louis Cardinals

The Number: 2.7

The Cardinals' 2.7 bWAR from their highest player disregards the challenges of tackling fan interest and attendance. A drastic and robust rebuilding strategy may be necessary to re-establish blue-chip talents to energize the franchise and fanbase alike, indicating the urgency of development in scouting.

Washington Nationals

The Number: .268

With pitchers allowing a batting average of .268, Nationals face significant hurdles. New pitching coach Simon Mathews has a tall order to rebuild a reluctant staff. Identifying talent and improving strategies will be critical in changing course and lifting the team out of their current pitching nightmare.

Conclusion

The landscapes of the National League are shifting as teams gear for the 2026 season. Each stat highlights critical issues to address. The journeys ahead will reveal whether or not these franchises can elevate their game and continue the legacy of Major League Baseball.
