Guzman is out of the lineup for Wednesday's game against the Orioles, Rhett Bollinger of MLB.com reports.
Guzman had started in each of the Angels' last five contests, but he'll get a break Wednesday while Vaughn Grissom covers the hot corner. The 22-year-old has been in a rut at the plate since the All-Star break, going just 6-for-40 (.150 average) with one home run, one stolen base, three runs and two RBI.
