someone far more intelligent than I offers a fitting note of departure for Mike "second-ugliest met to dave weathers" Stanton...


Michael Wolverton, a San Francisco-area computer research scientist who also writes for Baseball Prospectus, an influential statistics think tank, devised a system by which each situation a reliever can enter - bases loaded with one out, man on first with two out, etc. - is converted into the number of runs that typically score. The reliever is then judged by how many runs he allows either above or below average.

Wolverton's statistic, called inherited runs prevented, not only counts the pieces of runs a reliever either saves or allows, but also adjusts for runners he may bequeath to a pitcher who follows him.

The Royals' Nate Field, despite his rather pedestrian 3.77 E.R.A., is the 2004 leader in Inherited Runs Prevented with 8.0 total runs saved. On Tuesday, Field entered a game with none out and the bases loaded, and got three straight outs to save Kansas City 1.92 runs.

Inherited runs prevented also shows just how disastrous the Mets' Mike Stanton has been in 2004. Though Stanton, a veteran left-hander, had a 3.75 E.R.A., he did not save any runs but in fact cost his team 6.3 runs, third worst in the majors.
