Stassi is out of the lineup for Sunday's game against the Orioles, Jeff Fletcher of The Orange County Register reports.
Stassi is receiving some routine maintenance after he went a combined 1-for-10 with a walk and a run scored while starting each of the past three games at catcher. Kurt Suzuki will replace Stassi at catcher in the series finale, forming a battery with southpaw starter Jose Suarez.
