Gray (elbow) will make his next rehab start for Triple-A Rochester on Tuesday, Bobby Blanco of MASNSports.com reports.
Gray is expected to work around six innings or 90 pitches Tuesday after firing five innings and 79 pitches in his last minor-league rehab start Wednesday with Double-A Harrisburg. If all goes according to plan, Gray could return from the 15-day injured list and slot back into the Washington rotation following Tuesday's outing.
