Now under Dunn's "more stats" it is listed:
1.79 for Dunn, 2.13 for all batters. So, Dunn has fewer SO per BB than the average for all players, a plus for Dunn that was not mentioned by the Yankee announcer.
But why isn't a stat that is often mentioned for pitchers, seldom, if ever, mentioned for batters? Most batting stats can be applied to pitchers. Some pitching stats cannot be applied to batters, most obviously, Earned Run Average (ERA). But why not use common stats?
Batters are measured by SO/AB, pitchers by SO per 9 innings (SO9). SO9 includes outs made by batters on the bases, so it's less accurate. Maybe that difference doesn't change it much, but it might, especially for the relief pitchers.
These pitching stats are per 9 innings:
- BB + Hits (a.k.a WHIP: walks plus hits per innings pitched)
What the heck?
WHIP is for Wimps March 8, 2013
The variables are the same as those for on base percentage (OBP) for batters, which is something that is familiar. Why not use OBP? Why dream up something else and put it into a pitcher’s context that requires translation to have meaning? ...
For me WHIP has become one of those annoying items that people toss around to show off how much they know. If someone wakes you up in the middle of the night do you really know what a good WHIP is? I’m wide awake and I can’t tell you. Even when groggy I’m likely to know a good BA or OBP. What’s the deal with WHIP?
Less accurate, less meaningful. That's the pitching specific stats that correlate directly to familiar batting stats. Give me OPS+ for pitchers!
