It was just four days ago when Ross received a spot start in Brandon McCarthy's stead, allowing two runs on one hit with six strikeouts over six innings against the Padres in an eventual no-decision, before being optioned to Triple-A Sacramento the next day.
For Ross to be eligible to return to the roster before his required 10-day Minor League stay is up, he would have to replace an injured member, as he's expected to do. Colon appears bound for the disabled list any day now, as he rests a strained right oblique he sustained in Sunday's outing.
On the mend, meanwhile, is Jordan Norberto, who is expected to be reinstated from the DL as soon as Thursday, after missing most of June with a left shoulder strain. Norberto struck out two in one perfect inning of relief in a rehab stint with Triple-A Sacramento on Tuesday.
