Millwood's minor league deal called for an opt out if he wasn't called up from the minors by May 1. That day has came and he's gone.
Millwood is now a free agent and I know of a couple of teams that could use his services,even though he lasted only two innings in his last start.
Millwood went 2-1 with a 4.50 ERA in three starts at Double-A Trenton and Triple-A Scranton/Wilkes-Barre.
Millwood isn't the greatest thing going, but he should be signed by someone before long.
