Overview

• Peña was a late scratch Sunday with left oblique soreness, and Mauricio Dubón shifted to shortstop as Houston reshuffled its outfield with Jesús Sánchez to left and rookie Zach Cole to right.
• There was no immediate timetable for Peña, who is set for imaging Monday, and GM Dana Brown said initial evaluations suggested a minor issue that could be short term.
• The Mariners completed a three-game sweep in Houston, leaving the Astros trailing in the AL West and behind Cleveland on a tiebreaker for the final wild-card spot entering the last week.
• Peña has been a key contributor during a breakout season and previously missed 27 games after a June rib fracture, underscoring the impact of any new absence.
• The Astros remain shorthanded, with Yordan Alvarez sidelined by a left ankle sprain and not traveling to Sacramento, though he could meet the team in Anaheim, and closer Josh Hader on the injured list.
