Brantley is not in Wednesday's lineup against the Giants, Chandler Rome of the Houston Chronicle reports.
Brantley will head to the bench for Wednesday's series finale following a string of six straight starts during which he went 2-for-24 with a pair of doubles. The Astros are going with an outfield consisting of Kyle Tucker, Myles Straw and Josh Reddick (from left to right) in Brantley's absence.
