THE PATH FORWARD

The Houston Astros, once known for their relentless offense, are struggling mightily at the plate in 2025. A lineup that ranked eighth in OPS and slugging percentage just last season now finds itself near the bottom of the league in key offensive metrics.

Through mid-April, the Astros rank 26th in OPS, 27th in slugging, and dead last in doubles. It’s a steep drop for a team that once terrorized opposing pitchers with a deep, disciplined lineup. Simply put, Houston’s days as a Top 10 offense appear to be in the rearview mirror.

Still, there are some signs of life beneath the surface—particularly from Yordan Alvarez and Jeremy Peña. Advanced metrics suggest both hitters have been better than their traditional stats would indicate. Peña’s expected batting average (.320) ranks in the top 7% of the league, and Alvarez continues to scorch the ball, with elite exit velocity and an expected slugging percentage north of .500. Better results should be on the horizon for those two.

But outside of Alvarez and Peña, the story is less encouraging. Christian Walker and most of the roster haven’t been victims of bad luck—they just haven’t hit. Jose Altuve, while producing at the plate, may be overperforming. His expected stats lag far behind his actual results, suggesting regression could be coming.

The bright spot for Houston has been its pitching staff. The Astros currently boast the 10th-best ERA in MLB and rank second in strikeouts. Hunter Brown, in particular, looks like the emerging ace of the rotation—a welcome development for a team searching for stability.

Unfortunately, there may not be a quick fix for the lineup. General Manager Dana Brown has limited options. The farm system lacks top-end hitting prospects ready to make an impact, and acquiring a bat via trade or free agency would likely push the team over the luxury tax threshold—something ownership appears unwilling to do.

The broader concern is structural. Even with financial flexibility on the horizon as large contracts expire, the Astros remain reluctant to offer deals longer than three years or worth more than $60 million—unless you're Jose Altuve. In today’s market, that simply doesn’t get it done for All-Star caliber players in their prime.

With their window as a perennial World Series threat seemingly closing, Houston may face a tough new reality. The days of star players taking discounts to join a powerhouse are over. Right now, the Astros look like a team caught between eras—no longer elite, not quite rebuilding, and running out of ways to recapture their offensive magic.

That said, there’s still plenty of baseball to be played. A strong series against the Padres could significantly boost their overall numbers, especially with the sample size still relatively small.
