Alvarez is not in the lineup for Monday's game against the Red Sox, Eduardo Encina of The Baltimore Sun reports.
Alvarez is off to a dreadful 1-for-15 (.067) start to the season, and the Orioles are facing tough left-hander David Price on Monday, so manager Buck Showalter decided to hold Alvarez out for the first time this season. Matt Wieters will serve as the Orioles' designated hitter Monday.
