Altuve is out of the lineup for Saturday's game against the Rangers, Brian McTaggart of MLB.com reports.
The Astros haven't suggested that Altuve sustained an injury in Friday's 4-3 win, so his absence from the lineup is likely just a pre-planned maintenance day. With Altuve getting his first day off since returning from the 10-day injured list June 19, Tony Kemp will step in at second base.
