The Astros are closing in on a deal with free agent infielder Ronny Cedeno, a baseball source has told Cedeno was released by the Cardinals earlier this week. Cedeno, 30, will provide some middle infield depth for the Astros, who have yet to see either Tyler Greene or Marwin Gonzalez seize the starting shortstop job. Cedeno has played mostly shortstop in his career, but he can play second. Astros general manager Jeff Luhnow couldn’t be reached for comment.
