Butler (shoulder) will make his first rehab start at High-A Modesto on Saturday, MLB.com's Cody Ulm reports.
The Rockies plan to cap Butler at 60 pitches in the outing, after he performed 45 throws during a simulated game Tuesday. Butler is expected to make at least two rehab starts while he battles back from right rotator cuff inflammation, with his next turn to come July 17 with Triple-A Colorado Springs. If all goes according to plan during the two outings, Butler would then slot back into the big league rotation July 22, when the Rockies would have their first need for a fifth starter following the All-Star break.
