From this article on ESPN today: http://insider.espn.go.com/mlb/blog?name=olney_buster&id=6076120
NL Success rates for pitchers who threw sliders:
#1. Johnny Venters - BAA: .074, SLGA: .088, OBPA: 1.25, OPSA: .213
#2. Billy Wagner - BAA: .086, SLGA: .151, OBPA: .104, OPSA: .255
Simply amazing how good the back end of our BP was last season. Here's hoping that Everyday Johnny and the Kid Kimbrel can repeat their success from last year and have great years again this year.
Once again, our BP should be one of the deepest and best in all of baseball land.
