What does a high FIP mean?

FIP is similar to ERA, but it focuses solely on the events a pitcher has the most control over -- strikeouts, unintentional walks, hit-by-pitches and home runs. For example: If a pitcher has surrendered a high average on balls in play, his FIP will likely be lower than his ERA.
