Pena (hand) is batting leadoff and starting at shortstop against the Athletics on Saturday, Chandler Rome of The Athletic reports.
Pena missed each of Houston's past two games after being hit on the hand by a pitch Wednesday, but he's feeling well enough to re-enter the lineup Saturday. Nick Allen started each of the Astros' two contests at shortstop while Pena was out, but he's back on the bench upon the latter's return.
