A few years ago I made a nice profit looking at team records vs certain types of pitchers. Groundball/Flyball pitchers and Power/Control pitchers. I got the stats off of a site that was meant for fantasy baseball, but its not around anymore.
Its a lot of work to do it yourself. You have to find the mean groundball/flyout outs and then divide the pitchers into groups. Same with balls and strikes thrown for power vs controls. I guess once all that is done its not that hard to keep W/L stats.
Does anyone know a site that already tracks any of this?
I think I saw an article on this at baseball-insight.com
Also, covers.com shows the GB/FB ratios for the starting pitchers in Game Matchups, but unfortunately I could not find a listing of pitchers with these ratios anywhere. May be tedious having to go game by game, but not impossible.
