Per Rotoworld:

Athletics released first baseman Erubiel Durazo.
Durazo didn't show that his power was all the way back this spring, and he also struggled with the glove at first base. We'd still probably take him over Todd Walker, but the A's weren't willing to sacrifice the defense. Walker now looks like a $3-$4 pick in AL-only leagues.

Also, Donnie Murphy was assigned to AAA and Kurt Suzuki to minor league camp.

Finally, it looks like Loaiza will start the year on the DL
