Sandoval (biceps) will make his next rehab start for Triple-A Worcester on Thursday, MLB.com reports.
Currently in the midst of his second rehab assignment of the season, Sandoval is being built up slowly while he works his way back from left biceps discomfort. During his previous rehab outing Friday with Worcester, the left-hander threw 16 pitches over 1.1 innings, allowing no hits and walking one batter.
