(Undated)  --  Felix Hernandez is looking to make his way back to Seattle before the end of his final season with the club.  The former Cy Young winner will make a rehab start tomorrow with Double-A Modesto, where he's scheduled to throw 45 to 50 pitches over three innings.  He's spent his entire 15-year career with the M's.  Mitch Haniger and Dee Gordon could be sent on rehab assignments next week.  Third baseman Ryon Healy has undergone hip surgery in Arizona, according to manager Scott Servais, but would not offer more details.
