During that stretch, Shaffer -- now 25 -- slashed .213/.310/.410 with 14 extra-base hits, including five homers, and 10 RBIs over 142 plate appearances. He was the Rays' Minor League Player of the Year in 2015 in a year when he batted .267 with 26 homers and 72 RBIs. He spent most of his Minors career at third base, though that position is occupied by All-Star Evan Longoria in Tampa Bay.

Aguilar, 26, has spent his entire pro career with the Indians' organization after being signed by the club in November 2007. In parts of the past three seasons, he appeared in 35 big league games, hitting .172/.234/.190 with 21 strikeouts in 64 plate appearances.
