Look what people have to say about the RLYW!

CAIRO just takes the Marcels and changes the underlying assumptions and components in a bunch of ways that make the Yankees look better.

Wow, two stupid posts in one day. I think you’ve reached your yearly quota.

I don’t know if any of you current posters were around for that, but if so, I just can’t understand how you can call yourselves Yankee fans. Pathetic quitters is what you sounded like. Of the lame posts I could stand to read, the only person who had any confidence in the Yankees at that point was a (yeesh) Red Sox fan.
Jeter is King

Quite the attitude you have SG. Maybe you should shitcan this blog and join Steve at WasWatching? Or follow some other stupid team that has made the PS 15 of the last 17 years. Jeez… and some people think Yankee fans are entitled.

Camden Depot: Measuring Bullpen Management: Bucking Up the Bullpen

A Hardball Times article suggested using WPA - WPA/LI as a measure of bullpen performance that would be useful in assessing bullpen management.  WPA is the acronym for Wins Probability Added.  This is calculated as the difference in win expectancy before and after an event. LI is the Leverage Index.  It is a measurement of how consequential a specific scenario is based on the inning, outs, score, baserunners, and baserunner position.  By using the two statistics in concert, you arguably have a measure that gives you a context neutral wins added metric.

WPA WPA/LI WPA - WPA/LI
Bob Melvin 3.75 0.83 2.92
Bruce Bochy 2.98 0.13 2.84
Joe Giraldi 7.37 4.88 2.49
...

Joe Girardi makes the top three, which confirms my belief that he manages his bullpen about as well as anyone in baseball and has done so since he’s come to the Yankees.  I mean, the man got useful innings from Jose Veras.
