End-of-term Catch Up: Teach Your Kids to Throw Left-Handed

The end of the academic term is M-U-R-D-E-R on the baseball commentary.

Measuring the Corps of Relievers, after 14 April 2010. (Yes, you remember - Philadelphia 14 — 7 Washington. And Bergmann got the Black Spot.)

Matt Capps      .352
Tyler Clippard  .188
Brian Bruney   -.056
Jesse English  -.074
Tyler Walker   -.123
Miguel Batista -.259
Jason Bergmann -.485
Sean Burnett   -.509

Those numbers are the cumulative amounts of win probability added or deducted during all the individual relievers' stints between Opening Day and 14 April. Really, Burnett, loser of half a game all by himself, was the man doing the least. (Plus he was more evenly bad, while Bergmann loaded all his bad into one outing.)

But Burnett's left-handed.

So boys and girls, remember — baseball is more forgiving of left-handed pitchers.
