Gurriel (knee) will begin a rehab assignment with Double-A Amarillo on Wednesday, Jody Jackson of Bally Sports Arizona reports.
Gurriel has been playing in extended spring training action and is ready to test things out in an official game setting. Working his way back from surgery to repair a torn ACL in his right knee, Gurriel will play seven innings for Amarillo in his first game and build up from there. He is expected to be limited to designated-hitter duties initially upon his return to the Diamondbacks.
