I mentioned Paredes exit velocity, which is ironic since I usually don't get too interested in that, but I don't mean to indicate I think it's a bad move,
It is a worthwhile move to send Morel to a team that has been wanting him, and to get a guy better offensively (at this point) and defensively.
Morel may have a higher offensive ceiling, but if you can't play him anywhere that becomes less of an advantage. And he's not done well at all offensively this year. He hits HRs because he always seeks HRs even when the situation doesn't call for it. It's time for a change, for him and the team.
Paredes may be a 20 HR guy annually and if he can play good 3rd base, it's a step in the right direction. He has a career OPS+ of 118 and it is better than that this year. He's young and under control, so it's worth taking the chance. It's not a terribly costly move, and he has a little versatility in that he can also play 1st.
Morel brought enthusiasm, and his power will always give him potential to become a better player. I was fine early in the season with the decision to give him a long leash at 3rd to see what he could do, but clearly that did not work out.
I don't think anyone is sorry to see him move on.
