He started at shortstop and collected three of Houston’s seven hits Friday night. …Pena’s return will allow the Astros to move Carlos Correa from shortstop to third base. Correa started at third on Friday night but played shortstop after Pena left the game in the 10th. The Astros acquired Correa in a trade with Minnesota on Thursday. … Gordon will face the Red Sox for the first time in his career, and Buehler is 1-1 with a 3.00 ERA in three career starts against Houston.
