Mostly everyone is available, and everyone here but Luther is free.
Adam Brandt, Closer, 35 yrs - He's got a 1.80 ERA with 24 saves so far this season. I'm not asking for much, maybe a decent MR spec. Hopefully a contender will want him.
Chris Ray, Reliever, 35 yrs - He's having a down year, but in a good situation with good defense. I'm sure he'd be awesome for a contender. Keep in mind my short stop has 4 range, and my 3B is a horrible fielder. I'm sure that doesn't help this pitching staff.
Chase Ulrich, First Base, 30 yrs - He won a gold glove, and has some pop in his bat. Inexpensive, good D, and signed for two years.
