Houston's dismal 11-19 start, including a 3-11 road record and 5.97 runs allowed per game, stems from outfield injuries sidelining Jake Meyers, Taylor Trammell, and Zach Dezenzo, though Yordan Alvarez's 11 early homers offers offensive hope. Baltimore (14-15) benefits from home splits despite placing Trevor Rogers on the 15-day IL with illness.
