Astros Hitting Coaches: Evaluating Impact as Offense Stabilizes in May

As May unfolds, the Houston Astros’ offensive performance has sparked a critical examination of their hitting coaches. Early in the season, the Astros were riding high, leading the American League in runs scored while demonstrating a newfound discipline at the plate with increased walks and pitch selections. However, as we approach the end of May, it becomes evident that these gains may have plateaued, prompting an investigation into the lasting effects of the coaching philosophy.

In previous articles, we’ve delved into the concept of bases per out (BPO), and this time, we’re taking a broader look at the entire offense. To provide context, we’ll reference the 2025 season, which was marred by struggles that ultimately led to the dismissal of the previous hitting coaches. With one notable exception—Yordan Alvarez, who spent much of 2025 sidelined—most of the current roster remains intact. This raises the question: Are the changes in performance significant enough to attribute them to the coaching staff?

To understand the current state of the Astros’ offense, we can look at BPO+. For reference, the major league BPO in 2025 stood at .670, while the current season’s BPO is slightly lower at .663. Notably, Daikan Park has transitioned from being perfectly neutral last year to playing one percent above average this season. These figures suggest that while improvements are present, they may not be as pronounced as initially believed.

Despite a promising start, the Astros face challenges, including the absence of Jose Altuve for a month and Carlos Correa for the remainder of the season. Additionally, potential trades before the August 3rd deadline may further impact the lineup. Assuming stability in the roster, we can identify where gains have occurred, allowing us to distinguish between talent and approach in the batting order.

The BPO formula incorporates four key components: total bases, walks, hit by pitches, and stolen bases. While total bases largely hinge on hitting talent, walks are primarily influenced by the team’s approach at the plate. As we dive into the numbers, it’s important to acknowledge usage patterns, which we will explore in future analyses of infield and outfield performance.

With 49 games played this season, examining per-game averages will provide insight into growth. A 30-point increase in BPO is noteworthy, but the per-game statistics may reveal subtler shifts. This representation underscores how minor adjustments can yield significant results over time.

When evaluating the relative impact of each metric, it’s clear that walks and total bases are the driving forces behind the Astros’ offensive performance. The 2026 lineup is averaging nearly 0.6 more walks per game compared to 2025, contributing to an overall increase of almost one base per game. This difference could be pivotal in determining whether the offense is below or above average.

The critical question remains: What accounts for this improvement? Is it an overall enhancement in hitting philosophy, or are we witnessing isolated advancements from individual players? While Alvarez has consistently performed as expected this season, other hitters like Christian Walker have also shown notable progress. However, Jake Meyers and Jeremy Pena have not yet returned to their previous form, leaving room for potential growth. Additionally, a more productive Yainer Diaz could further elevate the lineup.

As the season progresses, the narrative surrounding the Astros’ hitting coaches continues to evolve. Are they the architects of improvement, or is it driven by individual player performances? With a long season still ahead, the answers may unfold in the coming weeks.
