The veteran left-handed hitter simply stays ready for whatever scenario manager Robin Ventura throws his way.
"You know whatever is asked of me is what I'm going to do," Johnson said. "If it's come in late and get late at-bats, that's what it is. I have to go out and make the best of the opportunity as much as possible, come in and stay positive and let my ability show. That's all I can do."
Ventura plans to get Johnson some looks at third base, having focused early on getting Brent Lillibridge, Ozzie Martinez and Eduardo Escobar at-bats at that position. Johnson has worked at third and in the outfield during morning drills.
"I'm preparing myself, yes," Johnson said. "If I'm called upon to go to third, I can play third. If I'm called upon to go to first, I can play first. If I'm called upon to go to the outfield, I can go to the outfield.
"Nothing is handed to you in this game and I'm in a new organization and I have to go and prove myself. They don't know me besides the fact they played against me. I have to show this organization what I have and go out there and hopefully show them that I have enough to be able to help them."
