The former Mets slugger has only played first base with some small stints at the DH spot, so he's not the most versatile player from a defensive standpoint. Based on his good health, productivity, and on-field presence, Alonso would be required at first base for Toronto. This would push Gurrerro Jr. to third base and or a rotation of each player between first base and designated hitter unless Alonso was to transition to a full-time DH role. Ideally, managing the infield load for both players would be beneficial, especially on an injury-generating turf field, but both players do have a solid track record of staying healthy so far in their careers. -Prasad
