It wasn't gutsy, just incredibly stupid and self-serving. He walked out on his team, plain and simple. If a player tried to pull this (like K-Rod going home if the Mets did things to make sure his option didn't kick in) there'd be a grievance filed. And it's not like he's getting a managerial job elsewhere regardless, his only chance of being a manager next year was to ride it out with the Nats and hope they picked up the option.
he was interviewed on WFAN and he said that the management and owners are clueless. i think he was ranting that he has them over .500 blah blah and that he only wanted a committment on his future
