Grayson Rodriguez (back) allowed one run in four innings in a rehab start for Low-A Rancho Cucamonga on Sunday.

Rodriguez allowed five hits and a walk and struck out four. The right-hander will assuredly need at least one more rehab outing before coming back, but assuming all checked out well Sunday and there’s no setbacks after that next outing, he could be back with the Angels around the All-Star break.
