You'll probably find one in Philadelphia too!
It's a little odd they re-signed him as a minor league free agent in the first place but maybe that does speak to how good the relationship was. Might also be a situation where it was less that the Phillies didn't have room for him under the organizational cap as, they both realized he was never going to get back up to MLB (as wound up also being the case last year ultimately). If he really wants one more kick at the can in what he's calling his last season he's probably better off somewhere else. Doubly so if he's still holding out any hope beyond that. Or he might just be ready to stop.
Of course it being the Phillies it's also easy to imagine they didn't want one of their minor leaguers blogging and tweeting his way through the season, especially with frank talk about minor league life and player rights. But, he said - on Twitter, naturally - that the release's timing was coincidental. He probably does want to find a new team if he can - better for the blog.
