Chirinos is not in the starting lineup Saturday against the Orioles, Chandler Rome of the Houston Chronicle reports.
Martin Maldonado will handle catching duties and bat eighth against right-hander Aaron Brooks. Chirinos has only started in three of the past eight games since Maldonado was acquired by Houston on July 31 and is 2-for-11 with four strikeouts over that span. The 35-year-old backstop is slashing .223/.325/.423 in 251 plate appearances against righties.
