Last November, the Miami Marlins made a huge blockbuster trade with the Toronto Blue Jays that sent Jose Reyes, Mark Buehrle and Josh Johnson to Toronto for a plate full of prospects. The Marlins seemed to have gotten the better deal in that trade after no one performed very well. In fact, Johnson missed most of the season with injuries that plagued him during his time in Miami.
Now that Johnson may hit the free agent pool next month, any chance that the Marlins have at going after him should be forgotten because the Marlins should leave him alone. Being injury-prone is only one of the reasons why Miami needs to stay away.
Miami has four pitchers that are going to be the core of the rotation for time to come. The organization also has Andrew Heaney in the farm system. He is making progress and may see time up with the Marlins next season. Adding Johnson to the team only crowds the rotation even more and part of the reason why the Marlins got rid of him in the first place was because he is so injury-prone.
Last season, Johnson was 2-8 in 16 starts with a 6.20 ERA with 83 strikeouts. Toronto finished well below what they were expected to (last place in the American League East). Signing Johnson on a one-year deal would be an unnecessary impulsive move that Miami does not need to make.
