Zunino is not in the lineup Thursday against the Orioles, Shannon Drayer of 710 AM Seattle reports.

Analysis:

Zunino was expected to sit for the day game following an evening contest, and will give way to the newly acquired Welington Castillo behind the plate. Following a dreadfully slow start, Zunino has improved his batting average more than 100 points from April to May, and is still considered the starter over Castillo.
