Gio Gonzalez, after offseason in spotlight, doesn't break a sweat

One day last week, as teammates packed bags and readied for the escape from spring training, Gio Gonzalez walked to the center of the Washington Nationals clubhouse in Viera, Fla. He fiddled with the stereo until Louis Armstrong's "What a Wonderful World" blared from the speakers. Gonzalez spun around to face nobody in particular and raised his fist, apparently, in salute to his own musical taste.
