Diaz signed with the Mariners out of the Dominican Republic and reached low Class A by age 18 despite not showing much with the bat. Midway through 2010, Seattle traded him and Ezequiel Carrera to the Indians for Russell Branyan and cash. Diaz spent most of 2012 in Double-A, but he made his major league debut with a five-week cameo at the end of May and finished the last three weeks of the season in Triple-A. Despite being 6-foot-4 and having just 30 speed on the 20-80 scale, he's at least an average if not better defender at shortstop. His plus arm is his best tool, while his hands are solid and he reads the ball well off the bat. Offensively, there's not much going on. A switch-hitter, Diaz has a choppy swing plane and an undisciplined approach that results in a lot of outs. He occasionally will put a charge into the ball to his pull side, but he has below-average power. Diaz doesn't profile as a regular, but he could make it back to the big leagues in a backup role.
