For the Astros, Diaz should serve as a utility infielder in 2019. He might also see time in the outfield as the likely replacement for free agent Marwin Gonzalez (who is not expected back in Houston). The 28-year-old Diaz should see ample playing time because of his versatility.

The Blue Jays have a surplus of infielders heading into 2019, so they could afford to ship Diaz out at this time. In Thornton, Toronto lands a solid right-hander who can both start and relieve. The 25-year-old is close to debuting in MLB and is a decent pickup for the Jays.

Diaz moves to the contending Astros, where his fantasy stock may be dependent on his playing time. He will be a solid addition to a fantasy bench next year, especially for all Carlos Correa, Jose Altuve and Alex Bregman owners. Since he will not go into '19 with a starting job in Houston (in all probability), Diaz may not need to be drafted in most league formats. He could be a waiver-wire addition during the season.
