Frazier (elbow) began a rehab assignment with Triple-A Salt Lake on Sunday, going 0-for-3 with two strikeouts.
Frazier played in his first game in more than six weeks as he battles his way back from right elbow inflammation. He played six innings at second base in his first rehab contest, and the Angels will likely want to see him get in at least one full game before returning him to the active roster.
