On Monday I touched on the idea of examining how hitters have performed against specific types of pitchers to try and find good daily matchups. Because a batter’s performance against a specific pitcher is too small of a sample to be predictive, why not look at a batter’s performance against that pitcher and others like him?
Let me qualify everything I’m about to say by saying that this method of choosing batters is merely something I am exploring. Despite the increased sample size I can get by looking at a batter’s performance against similar pitchers, it’s still usually not a huge sample size. And I’m also doing a pretty crude job of finding similar pitchers. I’m considering strikeout and walk skills, groundball and flyball tendencies, frequency of fastball usage and velocity as my variables in finding similar pitchers.
It’s hardly scientific and nothing close to exact. But I’m almost positive it’s a better approach than just using simple batter-versus-pitcher data. But I’m not sure it’s better than just looking at how a batter has performed against either left or right handed pitching as a whole. Read the rest of this entry »
