After all the rehabilitation he's gone through, Marlins ace Josh Johnson is ready to expand his limits, not restrict them.

The hard-throwing right-hander hopes the organization isn't considering holding him back in any way.

"Hopefully, it never really comes to that, and I can learn a lot of stuff about myself and what works best for me in the long run," Johnson said.

The Marlins have made it clear they will closely monitor their ace.

Johnson missed most of last year due to right shoulder inflammation. His last big league start was on May 16 at the New York Mets. Due to the injury, the two-time All-Star made just nine starts and threw 60 1/3 innings.
