Pena is not in the Astros' starting lineup against the Angels on Saturday, Matt Kawahara of the Houston Chronicle reports.
Pena will take a seat after going 2-for-5 with a run scored and a stolen base in Friday's 6-2 loss to the Angels. Carlos Correa will shift over to shortstop while Isaac Paredes gets the start at third base Saturday. Pena appears fully recovered from the fractured fingertip he sustained in early March, but the Astros may continue to monitor his workload in the early going after he missed most of spring training.
