Even though I am not high on Lopez, I like the deal primarily because it is an AL only. Same deal in a mixed, I probably hold off.
The thing with your AL only is that I think locking in an every day 2B is important. If you have all three of the 1B UTIL and CI spots filled with 1B, you limit yourself in flexibility which becomes pretty important with the single-league position scarcity.
I have a link here that deals with an almost similar issue, but in a mixed league.viewtopic.php?t=367302
