EDGE Analysis

Neither McCormick nor Michael Brantley (shoulder) will be able to return to the lineup for Houston during their three-game series in Seattle. McCormick has been on the injured list since the middle of April with his strained back, but he should return to a regular role by the middle of May if there are no setbacks.
