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."

Garza, who was expected to be dealt last season before getting injured just over a week before the non-waiver trade deadline in July, is in the final year of his contract and can be a free agent at season's end for the first time in his career.

Garza knew he was the subject of trade rumors last season and wanted to come out of the All-Star break "guns blazing," but a start against the St. Louis Cardinals on July 21 turned out to be his last one. He was first diagnosed with a cramp in the back of his right arm. That injury eventually was determined to be a stress reaction, and his season ended with a 5-7 record and 3.91 ERA.

Garza said he was throwing well and then felt something.

"I was really upset," Garza said. "I was like 'Damn, how was your last pitch, 96?'"

He still doesn't know what happened to his elbow.
