McCullers (shoulder) will make a rehab start Saturday at Triple-A Fresno, Brian McTaggart of MLB.com reports.
He threw 62 pitches at the Astros' spring training complex Monday, which should enable him to approach 75-to-80 pitches in Saturday's rehab start. The team's plans for McCullers beyond Saturday are unclear at this time, but he may only need one additional turn in the minors before he's ready to be activated from the disabled list.
