Johnson improving: Right-hander Josh Johnson threw off a mound to live batters Tuesday. Johnson, who has added a slider, has increased his workload without pain.
"He is right there like you would be throwing batting practice in (the start of) spring training," pitching coach Rick Kranitz said. There is no timetable yet for rehab games.
Asked about the chance of Johnson rejoining the Marlins in a month, he replied: "A month from today sounds good to me."
The Marlins would simply be happy to get him back by July. He missed spring training because of an irritated ulnar nerve in his right elbow.
