Marte (ankle) is not in the lineup for Saturday's matchup with Houston, Greg Johns of MLB.com reports.
Marte exited Friday's game with an ankle sprain caused by a slide at third base and appears to need some time off to return to full health. It's unclear at this point whether he'll need a stay on the DL, but in the meantime, Shawn O'Malley figures to see some fill-in starts at shortstop.
