Athletics catcher Landon Powell has cleared waivers, reports Susan Slusser of The San Francisco Chronicle (all Twitter links). She notes that Powell can refuse the outright assignment to the minors, but he's unlikely to do so because he'd forfeit his $620K contract for 2012. That contract is not guaranteed, however. Jane Lee of MLB.com says (on Twitter) he has eight days to make the decision.
Powell, 29, was designated for assignment following the Gio Gonzalez trade late last month as Oakland needed to clear 40-man roster space. He told Slusser back then that he hoped to get picked up by another club or traded. Powell is a .207/.284/.328 career hitter in 406 big league plate appearances, and he's thrown out 29 of 73 attempted basestealers during his career, a stellar 39.7%.
