Rodriguez (knee) is expected to start for Triple-A Pawtucket on Sunday, so it is unlikely that the Red Sox think he is ready to return yet, Jason Mastrodonato of the Boston Herald reports.
Rodriguez has a 3.54 ERA and 1.14 WHIP in five starts at Triple-A this season and appears to be nearing the end of his rehab assignments. If he performs well on Sunday there's a chance he could return to the Red Sox starting rotation sometime next week.
