Astros activated RHP Wilton Lopez from the 15-day disabled list. Lopez has a sprained ulnar collateral ligament in his pitching elbow, but he and the Astros believe he can pitch through it. Lopez, 28, has a solid 2.51 ERA and 26/4 K/BB ratio over 32 1/3 innings this year. He'll return to a late-inning setup role.
