(Arlington, TX)  --  At least one Mariner is drawing interest on the trade market.  The Indians and Rays are reportedly kicking the proverbial tires on outfielder Domingo Santana.  He has rebounded from a down year to hit .273 with 20 homers for the M's.  However, there could be an issue.  The Athletic reports the 26-year-old's right elbow has troubled him since the All-Star break and the team sought an MRI earlier in the week.
