This is the TEMPORARY home of the Stolen Base Threat ratings. This data will soon move to Plate IQ.
Soon, RotoGrinders Premium will be releasing new tools to help you find stolen base upside on a daily basis. I really couldn’t wait to start sharing what we’re cooking up, so I’ve elected to spill the beans on some of the information early. Below, you’ll find “Stolen Base Threat Ratings” on batters that may have more (or less) upside than usual when it comes to locating stolen bases.
The evaluation accounts for “Takeoff Rating”, “Success Rating”, and “Speed Rating.” I used data points from Baseball Info Solutions to pinpoint how often runners steal when given the chance, and compare it to how often pitchers saw their opposing baserunners steal. The catcher is also factored into the equation here. The result is a combined “Takeoff Rating.”
“Success rating” is more simple, and tries to balance out attempts with how often the attempts were successful for batters, pitchers, and catchers. This rating is normally lower than “Takeoff Rating” and is also weighted a lot lower in the final score. We also look at how fast the individual runners have shown themselves to be on the base paths. That’s another way to make sure the most likely SB candidates gravitate towards the top.
