Not a lot of clubs did either, i get it. I think of all the players you would take a flier on it would have been him. Its not like he tore his arm, it was fatigued by not pitching for 2 years.

Carlos (according to WSD), came to the White Sox and said if they matched the Giants offer he would have signed back on.
