The Red Sox (1-4) didn’t just lose Monday night in Houston (3-2). They looked like a team still searching for its identity. After an Opening Day win built on pitching and timely execution, Boston dropped its third straight game in an 8-1 loss to the Astros, and the formula that was supposed to define this roster never showed up. The offseason vision, anchored by arms like Ranger Suarez and Johan Oviedo, instead unraveled over nine uneven innings.
