Trout, who is not in the lineup for Thursday's game against the Mariners, is dealing with hamstring tightness, Maria I. Guardado of MLB.com reports.

EDGE Analysis

Trout was absent from the lineup Thursday for the first time all season, and the report of apparent hamstring tightness explains why. It's currently unclear how detrimental the hamstring tightness is and if he'll be forced to miss additional time. The star center fielder will be considered day-to-day for the time being. We should get a better idea of his injury status when the Angels release their lineup prior to Friday's contest against the Astros.
