McCullers (shoulder) will make his next rehab start July 17 with Double-A Corpus Christi, Brian McTaggart of MLB.com reports.
McCullers has logged three rehab starts thus far, with his last taking place with Triple-A Sugar Land this past Tuesday, when he allowed four runs (two earned) on three hits and three walks while striking out four across four innings. The right-hander pushed his pitch count up to 77 in that outing, but McCullers will require at least one more outing in the minors before Houston considers adding him back to its rotation upon activating him from the 15-day injured list. McCullers has been on the shelf since May 19 due to a right shoulder impingement.
