Alex Presley (right oblique) returned to action on Friday with the Tri-City ValleyCats after a two-day break. He’s to play one more game on Saturday, at which point another determination will be made. “Presley’s going to play the field tonight,” Astros general manager Jeff Luhnow said. “So that’ll be the next challenge for him. Really, it’s a matter of how he feels coming out of the game and how he feels tomorrow. If everything goes well, he’ll play again tomorrow.” First baseman Jesus Guzman (back spasms) played his first minor league rehab game on Thursday with Class AAA Oklahoma City, going 0-for-1 with a pair of walks, two runs scored and a strikeout. He’s not expected back as soon as Presley.
