Caglianone was scratched from the lineup for Sunday's game against the White Sox due to left groin soreness, Anne Rogers of MLB.com reports.
It's unclear when exactly Caglianone sustained the injury, though he's been scuffling at the plate over the past four games, going 1-for-15 with a walk, a triple and eight strikeouts. The 23-year-old will miss at least one start while he tends to the injury.
