Recent Red Sox pitching woes dominate sentiment, with reliever Justin Slaten landing on the 15-day IL (oblique strain) on April 8, joining absences like Triston Casas (knee, 10-day IL) and Patrick Sandoval (elbow), thinning their rotation and bullpen. Probable starters Dustin May (BOS RHP) and Connelly Early (STL LHP, 2.89 ERA) set a competitive pitching matchup, bolstered by St. Louis' home-field edge and solid early form amid mild weather (mid-60s, low precipitation risk). Boston's bats (.254 AVG) face a test versus lefty Early, while key Cardinals injuries like Lars Nootbaar (60-day IL) linger but haven't derailed their momentum.",
