Pennington cleared waivers Saturday and accepted an outright assignment to Triple-A Louisville.
Pennington was already with Louisville, having been optioned there Thursday. Now off the 40-man roster, he's one step further away from returning to the big leagues, though his versatility leaves him multiple avenues back to the show. With a career .242/.309/.339 line in parts of 11 seasons, though, don't expect much from him if he does end up back with the big club.
