Valbuena isn't in the lineup for Sunday's series finale against the Red Sox, Brian McTaggart of MLB.com reports.

EDGE Analysis

Just a .214/.306/.349 career hitter against southpaws, Valbuena will take a seat with the lefty Henry Owens on the mound for the Red Sox. Marwin Gonzalez will replace him Sunday, but Valbuena will likely slot back in Monday when the Astros travel to Seattle to face the Mariners and the right-handed Taijuan Walker.
