Stat of the DAY: SIERA.
Go go go. (Explanation please 
)
Urgh... there is a thread somewhere here where I went into detail about it. Marquis and I had an animated discussion. Maybe the Stats thread?
SIERA is like FIP but a slightly better predictor, especially of extreme pitchers. For example, it nails guys like Clippard and Hudson a lot better than traditional metrics do.
