Guardians won Thursday 4-2 behind Parker Messick's near no-hitter, but Orioles rallied 6-4 Friday amid Baltimore's injury crisis—13 on the IL including Adley Rutschman (ankle), Jackson Holliday (wrist), and Ryan Mountcastle (foot), thinning the lineup despite a strong 3.81 ERA staff (fifth in AL). Cleveland boasts healthier depth, Angel Martinez (.279 BA), and home-field advantage; Orioles counter with Gunnar Henderson's recent power (three HR last 10 games) and 6-4 form over past 10.",
