Overview
- Both Jeremy Peña and Christian Walker left Saturday’s game against Baltimore after in‑at‑bat incidents with Peña diagnosed with a right hamstring cramp and Walker with right hip tightness.
- The pair were omitted from Sunday’s starting lineup and Espada said he hoped the setbacks would be resolved in a day or two, though the club has not given detailed severity updates.
- Peña has missed extended time this season with multiple lower‑body injuries, including a right hamstring strain in April and a left calf strain before the All‑Star break, limiting him to about half the season.
- Walker has been an everyday player for Houston this year and underwent imaging on Friday after being hit by a pitch that showed no fracture, but his sudden hip tightness raised short‑term availability questions.
- The Astros have signaled short‑term contingency planning by removing infielder Raynel Delgado from Triple‑A and will add right‑hander Ronel Blanco to the rotation on Monday to bolster a struggling staff.
