EDGE Analysis

Pena hit atop the order in the Astros' first eight games of the season, but he'll move down the lineup after going 0-for-5 with four strikeouts Friday, which dropped his average to .171. Chas McCormick will bat leadoff Saturday as manager Dusty Baker tries to replace Jose Altuve (thumb) atop the lineup.
