Astros trader consensus reflects pitching depth concerns after placing Cristian Javier (grade 2 right shoulder strain) on the 15-day IL and Jake Meyers (grade 2 right oblique strain) on the 10-day IL yesterday, calling up J.P. France and Taylor Trammell amid early-season rotation woes with Hunter Brown also sidelined. Mariners (4-9) host the slightly better Astros (6-7) but contend with Victor Robles' recent 10-day IL stint for a pectoral strain; home-field advantage and McCullers' 3.21 career ERA in Seattle could sway a tight AL West matchup.",
