I am going to get laughed at for this... but I would call about Billy Hamilton.
He has utility. He is shockingly fast and he is an excellent CF. That alone is value, he can play a couple games a week if Kingery doesnt work out (or if, more likely, Kingery is needed at another position), he would be a very good defensive replacement and when you are down a run in the 9th inning having him come in to PR might win us a game or two during the year. He is one of the fastest runners IN BASEBALL HISTORY.
I know Hamilton doesnt get on base enough to take advantage of his skills, but he isnt being brought in to save the team, just to be our worst starter a few days a week and be a respectable bench player. He is a guy that would be really nice to have on the bench especially with Altherr gone and us lacking a backup CF (or even a starter now). He adds the utility of keeping guys like Cutch, Harper and Kingery out of CF in clutch late game situations.
He should be virtually free.
(NOTE: I lived in Pensacola when he was setting the all time SB record, so I have a bit of fascination with the guy, I admit it. He was a great player to follow for that summer)
