Chicago Cubs pitcher Matt Garza reported to camp and said Monday he is healthy and ready to try to prove the team should make a long-term commitment to him. "My goal is to prove that I'm healthy enough and make them want me to stay," Garza said on the first official day of spring training. "That's my job. Right now there's all the questions. 'How's he going to come back? How's he going to rebound?' Those are legitimate questions."
