Injury Report
Boston Red Sox
- Triston Casas — OUT (rib)
- Trevor Story — OUT (shoulder)
- Tyler O’Neill — Day‑to‑Day (hamstring)
- Kenley Jansen — Day‑to‑Day (back)
Impact: Missing Casas and Story removes two major power threats. O’Neill’s status affects Boston’s ability to hit left‑handed pitching.
Kansas City Royals
