Grissom was scratched from the lineup for Friday's game against the Dodgers with left side tightness, Rhett Bollinger of MLB.com reports.
The Angels are labeling Grissom as day-to-day, so although he won't be able to start Friday's contest, he doesn't seem to be dealing with anything too severe. Oswald Peraza will shift to first base while Grissom rests, opening up second base for Nick Madrigal.
