On that note, keep track of how many times the Cubs make an out on the basepaths. That's also a very good idea. Obviously CS is already a stat, but there's no stat for getting thrown out at a base for being way too aggressive (either trying to take extra bases or trying to take 3rd on a ball hit to the left side). http://www.baseballprospectus.com/statistics/sortable/index.php?cid=421535 Care to translate? Each stat in the middle corresponds to a different part of baserunning. One deals with stolen base attempts, another one deals with advancing on groundouts, another one deals with advancing on flyouts, another one on advancing on base hits, and finally advancing on things like wild pitches. The value of the extra base is compared to how many outs are recorded and then it's calculated how many runs were created or lost in each category compared to an average runner. Each is factored into the stat on the very right, which is how efficient the player was on the bases overall. Is there a category for outs made on the basepaths? It's not its own separate category, no. But tracking outs by itself is just as worthless as simply seeing how many extra bases a player takes without taking into account the risk. What it does is factor those outs into each of the other categories similar to how outs are factored into stolen base percentage, which based on that percentage and run expectancy charts we can figure out if trying for extra bases was worth it or not. All the outs that a player like Theriot made on the basepaths are counted against him in one of those categories, depending on what type of out it was. But it breaks it down into several different kinds of situations, so it is easier to see if a player is too risky in one area but provides reward in another baserunning area. its factored in there, but it's not explicitly listed there.
